Best practice for moving business numbers between providers, market by market.
Porting is what makes changing communications provider possible at all: it moves your existing numbers to a new platform without your customers noticing. This guide walks through how a port runs, what each region and country asks for, how long each one takes, and the twelve reasons ports get rejected.

Keeping your numbers is what makes changing provider possible.
Business number porting is the process of transferring existing phone numbers be they local, national, toll-free, or international from one telecommunications provider to another, all while keeping the same numbers recognisable to customers and stakeholders.
For organisations, porting removes a critical barrier to change, allowing seamless migration to new communications platforms, CCaaS, or global carriers without disruption to service, brand identity, or customer trust. This flexibility has become vital for modern enterprises expanding to new markets, consolidating technology, or seeking cost efficiencies and regulatory compliance on a global scale.
This informative guide is designed to demystify the often complex world of global business number porting. It walks decision-makers and operations teams through the why and how of porting—whether for a single site or a multi-country implementation.
The resource details common pitfalls, required documentation, best practices for continuity, and tips for maximising operational efficiency and business resilience. It is here to aid and equips organisations with the practical knowledge and confidence to upgrade their communications, improve service, and maintain a consistent presence no matter where or how they operate.
Porting is a governed process to promote fair competition and consumer choice in the telecommunications market by ensuring customers can switch providers without losing their established phone numbers. Regulations like those from the UK's Ofcom establish rules for providers, preventing them from creating artificial barriers to switching and ensuring that the porting process is efficient and protects consumers.
Although technically a simple process, number porting across multiple geographies and providers can be complicated and at times, lengthy. Each carrier may have unique requirements, regulations differ by region, and the smallest discrepancy in records can slow things down.
Drawing on over 15 years of hands-on experience navigating these nuances, Fortay helps businesses of all sizes engage with carriers, overcome roadblocks, and ensure every port is completed with minimal disruption.

02The porting process
The mechanics are simple. The paperwork is where ports fail.
1. Data Capture - Collect all details of every number in your estate - request a CSR from losing carrier. Time Frame - 4 weeks.
Update Records - Ensure all records are accurate for submission Time Frame - 2-4 weeks.
Collect Supporting Documentation
- Bills, Proof of Company etc. Time Frame - 1 week.
Complete the LOAs - Complete and review with Fortay before submission. Time Frame - 1 week.
Submit for Porting
Porting Accepted Time Frame - Dependent on if information is accurate.
Go Live Time Frame - Changes per country. Usually 4-6 weeks.
The time frames provided above are indicators of a typical process. This is NOT a guarantee and is dependent on the complexity of the estate, as well as continued support from
What information does a CSR contain?
A CSR generally contains important account information, such as:
Business name - The name of your business registered to your account. 2. Service address - The address that each phone number is registered to. 3. Billing telephone number (BTN) - The primary telephone number that references how the account is billed and set up. This information is key for a successful port, any information submitted for porting must match the losing carrier’s records.
03EMEA
Every EMEA market sets its own documents and its own clock.
Do not cancel your service with the losing supplier, as we cannot port inactive numbers, you will be at risk of losing your numbers before the port takes place. Porting dates cannot be expedited.
Plan ahead. It is advisable to plan ahead and minimise change requests to your port dates to reduce the risk of numbers porting when you are not ready. Some countries/carriers will not accept date change requests.
The information you provide must match exactly what is on record with your current service provider.
Port activations take place during business hours only in the local country of port.
In most European countries, the address noted on the LOA must match the geographic area code of the porting telephone numbers. Please check the country requirements in the list below.
You can also request a toll-free number port (EMEA).
EMEA region port activations do not take place on Bank Holidays.
Most carriers do not split blocks/ranges of numbers and must be ported in full. You must obtain details of all numbers in order to minimise rejections.
LOAs are to be hand/wet signed or electronically signed, where permitted, using DocuSign or Adobe. Images of signatures are not accepted and will result in your LOA being rejected and a delay in processing your port request.
If you have broadband installed on any of your porting telephone numbers, you will lose your broadband service once the number port completes.
If you have alarm monitoring services installed on any of your telephone numbers, you may find the number port request is rejected until the alarm monitoring services are moved to another line or ceased if you no longer need them. Contact your alarm service provider for assistance prior to submitting.

Lead times
With all porting, it is advisable to plan ahead and minimise change requests to your port dates in order to reduce the risk of numbers porting when you are not ready since some countries/carriers cannot accept date change requests.
Lead times for all EMEA ports are dependent on the regulatory requirements in the country of port and the responsiveness of the suppliers in the chain. The process is also dependent on the accuracy of the information provided. We will always keep you advised of progress.
Note: On the day of transfer, you will experience some loss of service to incoming calls during the port activation window while the numbers are being ported from the losing supplier. Porting can take place sooner or later than the lead times quoted.
UK
Porting in the UK takes an average of 30 business days, we can port sooner or later than this. Porting dates are dependent on the accuracy of your LOA information as well as the responsiveness of the losing suppliers. Industry lead times are to be followed.
South Africa
Porting usually takes an average of 45 days from the day of LOA submission to the losing carrier.
EMEA
The average lead time for porting is 30 to 60 business days. This may also depend on any contractual obligations with your losing provider. We can port sooner or later than this; therefore, please be sure to discuss porting dates with your Zoom Phone Porting Coordinator.
04US, Canada and Puerto Rico
North America is the most standardised region, and the fastest.
Porting Guidelines
Fill out the appropriate LOA (local/toll-free) and make sure it is dated and signed by the authorized person to port within 30 days prior to project submission
Provide a separate LOA for US Local, US toll-free, Canada, and different service/ physical addresses
Verify that the company name, authorized end user’s name, and service/physical address match the losing provider’s records

Current provider’s account number
If it is a wireless number, your 4-digit PIN (required for all wireless ports)
Porting Lead Times
99 Numbers or Less - Ports of 99 numbers or less can take between 4-21 days. Most wireless numbers will port in 4 business days; landlines will typically port in 7 business days from major providers, and 10 to 21 business days from smaller providers (including Canada).
Project porting (ports of 100+ numbers) within North America typically takes 3 to 4 weeks, depending on complexity (how many underlying carriers are involved, their individual SLAs, the quantity of telephone numbers involved, etc.). Our Deployments team can help set proper expectations on a case-by-case basis.
05APAC
APAC ports are measured in months, not weeks.
General guidelines
The information you provide must match what is on record with your current provider.
In most APAC countries, the address noted on the LOA must match the geographic area code of the porting telephone numbers.
Porting numbers need to be in the LOA rather than as attachments unless otherwise permitted.
DDI blocks of numbers may require full port as some countries do not allow blocks/ranges of numbers to be split.
Number portability checks can only be carried out once the order is submitted. There may be times when providers advise that numbers as non-portable.
You may experience some loss of service to incoming calls during the port activation window while the porting numbers are in progress.
APAC Porting usually takes months to complete from the day of submission. Lead times are discussed below.

APAC Country Guidelines
Singapore
Only fixed line numbers (+656xx) are portable as per a general rule.
Signed and stamped LOA must be correctly filled (matching donor’s records) and dated within the last 35 working days including the date you submit the porting request.
If a company stamp is unavailable, provide a company letter with company letterhead explaining why the company stamp is not available.
File a copy of ARCA Business Registration Certificate is required and must be included when requesting a number port.
Note: Unique Entity Number (UEN) or Business Registration Number (BRN) is a 9- or 10-digit identification number that the government issues in Singapore to all entities that operate within the country and must be included when filling out the LOA.
Partial porting (not porting all your numbers) may be supported but this depends on the agreement between your service provider and yourself, which needs to be arranged before the porting is requested. Because of the local regulations and the way numbers are allocated, partial porting is rarely supported.
A target port date when submitting your port request must be between 20-25 business days from the day you submitted the order.
Note: Your provider will inform you about the port-out activity and will require your approval to proceed.
We can easily cancel or re-schedule your port request up until the time when the port date has been scheduled. Once a port date has been scheduled, cancellation or re-scheduling of the port becomes more complex and riskier because the service providers involved may have already begun configuring your phone number. The further we are in the process when you decide to cancel or re-schedule, the less likely it is that we will be able to cancel successfully or re-schedule or re-schedule the port.
Please let us know at least (5) five working days before the scheduled day if you wish to cancel or reschedule an already accepted port order.
Note: This will be on a best-effort basis only.
Australia
Numbers can be ported in blocks or split up. If your current provider informs us that numbers are in blocks and need to port as such, but you do not want to keep them, let us know five working days before or after the port completes which numbers you would like to keep. The remaining numbers will be returned to the provider and can no longer be retrieved once returned.
For Toll-Free or Smart numbers (+1300) with EROU holders, please contact the EROU holder and work with them as the obligation is non-transferable. Click [here ](https://www.thenumberingsystem.com.au/#!/number-register/search)to find out if your Toll-Free or Smart numbers have EROU owners.

Once a port date has been scheduled, cancellation or re-scheduling of the port becomes more complex and riskier because the service providers involved may have already begun configuring your phone number. The further we are in the process when you decide to cancel or re-schedule, the less likely it is that we will be able to cancel successfully or re-schedule the port.
Please let us know at least four (4) working days before the scheduled day if you wish to cancel or reschedule an already accepted port order.
Note: This will be on a best-effort basis only.
For Toll-Free, a business address outside Hong Kong is required.
Malaysia
Only toll-free numbers MYS TM are supported for number porting at this time.
Signed Change Authorization and Designation of Agency must be correctly filled (matching donor’s records) and dated within the last 35 working days including the date you submit the porting request.
Please note that your application will undergo validation if eligible for transfer (this may take up to 7 business days). After confirming transferable numbers, the port will be sent to the losing provider for validation and a decision on port acceptance or rejection. Once the port is accepted, a change of agency can happen if the main customer of the local operating service provider agrees to the number transfer.

What is a losing provider?
This is the provider that you currently pay your telephone bills to. The losing provider name must always appear on your porting LOA.
Can I port my phone numbers?
Local or geographical numbers
We can port your local (sometimes referred to as geographical) numbers in all supported countries. The porting process itself is dependent on your current service provider and their acceptance of the porting request. In some countries, your porting date will coincide with the termination date of your contract with your current service provider, they may even reject the port. It would be advisable for you to check your current contract terms with your provider, note they may apply an early contract termination fee.
Toll-free or non-geographic numbers
We can port toll-free numbers in the US and Canada as well as other regions.
What is a DDI block?
A DDI block is a set of sequential numbers, without any gaps or missing numbers. If the service phone provider has built your numbers as a DDI block on their network (or their underlying suppliers’ network), then they may only allow the numbers to be ported away as a DDI block when you leave them. Contact your phone service provider for more details on the numbers you own and if they're part of a DDI block.
Can I call forward my existing numbers to my new Phone system?
Yes, you can. Contact your current service provider about forwarding your numbers before submitting your porting request.
How long will porting take?
North America: Ports of 99 numbers or less can take between 4-21 days. Most wireless numbers will port in 4 business days; landlines will typically port in 7 business days from major providers, and 10 to 21 business days from smaller providers (including Canada).
Project porting (ports of 100+ numbers) within North America typically takes 3 to 4 weeks, depending on complexity (how many underlying carriers are involved, their individual SLAs, the quantity of telephone numbers involved, etc.). Our deployments team can help set proper expectations on a case-by-case basis.
Latin America: Porting can take up to 60 days.
APAC: Porting can take 10 to 12 weeks.
EMEA: The UK can take up to 30 days while the rest of the EMEA region can take up to 60 days.
We will keep you updated throughout the porting process, and we will let you know once we have agreed on a firm porting date with your provider.
When should I cancel my existing service?
Your service must remain active with your current service provider throughout the number porting process. You will be notified by Fortay once your number has successfully transferred and you will be able to cancel your service with your old service provider at that time. Fortay does not cancel your service on your behalf.
Will my existing service work during the porting process?
Your existing service will work as is during the porting process if you do not make any account changes. Once your number has transferred over, your old service will no longer function.
Note: Any service interruption during the porting process must be raised to your provider.
Why is my order taking longer than usual?
Porting may take longer than the standard time frame. A lot of factors can contribute to the delays.
Common reasons include:
The number or account is under legacy or old infrastructure (Complex Port).
Your provider has an internal number migration (Common with VOIP/Cloud service).
Records may have been unclear due to the company merging.
Your provider's business rules have a long response time frame.
Could also be possible order volume related.
Why is my port request canceled?
Your porting request will be canceled if there is no response or update from you within 15 business days. Some orders will be automatically canceled if the system detects the following:
Phone numbers in the order belong to multiple underlying providers. This is common to most VoIP/Cloud-based phone service providers.
Phone numbers in the order are from multiple locations/addresses.
Why are my calls routing to my old setup after porting?
This happens when your previous provider/carrier, still has your ported numbers in their network. In the industry, this is called ‘Residual Translations’, and it is quite common.
Losing carriers have 24 hours in which to remove your newly ported number/s from their network. If they have not done so, or if you’d like to get them removed sooner, please engage your previous provider/carrier, and ask them to remove the numbers from their network/switch.
08Common issues
Almost every rejection traces back to one of twelve causes.
Address mismatch
The address submitted on the order does not match the address on the losing provider's Records. Most providers will require the service/physical address to be presented on the order, rather than the billing address.
Some countries in Europe and Asia require an address that matches the geographic area code of the porting numbers. Without this, the port request will be rejected and cause a delay.
Resolution:Fortay will work with the carriers and attempt to pull a record to resolve the mismatch. If they cannot obtain the records, you will need to obtain the correct information from the provider.
For porting in EMEA and APAC, you will need to contact your current phone provider to find out the correct address for your numbers.
Account number missing or invalid
Account Number Required: The provider requires the account number before approving the port. This generally assists in the verification process to prevent unauthorised ports. The account number is usually different than the account telephone number (ATN) / or billing telephone number (BTN) and is usually found on the bill. This is most common for mobile numbers.
Account Number Invalid: This means that the account number provided on the order does not match what the provider has on file. See the above topic for information on the account number.
Resolution: You need to obtain the correct account number, send it to us, and we will resubmit. This can usually be found on the bill.
Disconnected
The phone number or the account holding the phone number is disconnected, inactive, or suspended. Sometimes this means that the phone number itself is inactive (rings to a disconnect recording), or that the number is in a status with the provider that indicates an inactive account.
Resolution: All phone numbers need to be active to port. You may need to contact your service provider to re-establish the phone service.
Incorrect billing telephone number (BTN)
In the US and Canada, when we submit a port request to a provider, we give the BTN/ATN to the provider that was populated on the order. The provider will take that BTN and search for the corresponding customer record to obtain all the account details to approve the port request. If the BTN provided on the order does not allow the provider to pull up the account records, they will reject it back to us indicating the BTN is incorrect.
Resolution: Unfortunately, pulling a customer record on an incorrect BTN can prove difficult as providers often use that as a way of searching for your account. You will need to contact your service provider to obtain the correct BTN.
In EMEA and APAC countries, you will need to ask your current phone service provider for the correct BTN (or Main Billing Number) for your porting telephone numbers.
Name mismatch
The business or residential name on the order does not match that of the provider's customer records.
Resolution: Our partners will attempt to pull a copy of your records in hopes of resolving the mismatch. If our partners cannot obtain your records, you will need to obtain the correct information from your service provider.
Partial port/migration indicator
Partial port indicates that there are more numbers on the account than you may have initially provided to port. We need to know what those numbers are and what you would like to do with them.
The migration indicator is the setting on the port request that tells us if you are requesting a full port or partial port.
Both settings indicate an incorrect setting with the type of request. For example:
a partial port, but it is a full port; or
a full port was requested, but you are leaving numbers behind, thus it should be a partial port.
Resolution: The request must be updated to a partial/full port, depending on the rejection. If you plan on leaving numbers behind with your service provider, but you are porting the BTN (the main number on the account), you need to provide a new BTN to keep the account intact with the provider. The new BTN needs to be a number that already exists on the same account. We can talk you through this if you were to face this issue.
Partial order commit failure
This is an error you may see when first submitting your request. To fix the error, please update your BTN (Billing Telephone Number) field to reflect one of the numbers you are looking to port. Once updated, you should be able to submit with no issues.
Passcode/PIN required or invalid
Some providers require a PIN or passcode to authenticate and approve the port request:
Passcode/PIN required: Indicates that a passcode/PIN was not provided on the order and needs to be.
Passcode/PIN invalid: Indicates that the passcode/PIN supplied on the order is not correct, according to the provider's records.
Resolution: Unfortunately, we, nor our porting partners can obtain this information. Obtaining/setting up the PIN can only be done by an authorised user on the account. This is required by all mobile providers, and it is best practice to contact your mobile provider and update your account PIN instead of asking the current.
Pending order
A pending order can be another port request that has been submitted with the same number; a feature added or disconnected, or an address change. If there is an active order on the account, it will prevent your numbers from porting. Even if you only requested a name change or billing address change, they all contribute to a pending order rejection. This could also mean that one or more numbers are being ported on separate orders.
Resolution: If you are not sure what the pending order is, you will need to contact your service provider to resolve the issue. Sometimes a simple change is delayed in a queue on the provider's side and never completed. Once resolved, we can resubmit the order.
Lock or freeze
A porting application may be rejected because your service provider placed a freeze on your account or phone number.
Resolution: Contact your service provider to remove the lock or freeze.
Copy of the bill is required
You did not attach a copy of your bill to the porting request, or your bill is outdated.
Resolution: Upload a copy of your bill that is dated within the last 45 days.
Authorised name mismatch
Your order may be rejected because the person listed on the request is not authorised to make account changes with your provider.
Resolution: Contact your provider and validate the person in their system that is authorised to make changes.
