United Kingdom Porting Beta

Below are instructions for porting United Kingdom phone numbers into Twilio.

  1. Submit your Porting request to porting@twilio.com. To have a successful port, you must follow these steps:
    • The authorized user or owner’s first and last name.
    • We are able to port in Geographic, Non- Geographic, Mobile and Tollfree numbers. Please provide the full list of numbers that you wish to port.
    • The corresponding service address. This must be an actual physical address. PO Boxes are not valid addresses.
    • A GNP Letter of Authority (LOA) or NGN Letter of Authority (LOA). Numbers starting with 03 and 08 fall under Non Geo (NGN). Numbers starting with 020 and 01 fall under Geo (GNP) signed by the authorized user and/or owner of the number(s). Note that the information on your LOA must match the authorized user name and service address provided by your current carrier. You can find the GEO and NGN LOA's required for United Kingdom numbers below. 
    • A Customer Service Record (CSR).
    • A scanned (or electronic) copy of the most recent phone bill (within the last 30 days) that includes the account, owner/authorized user name, and address information for all the numbers you’d like to port.
    • Tip: Read the most common reason for rejections to avoid them.
    • A PAC Code (Porting Authority Code) is necessary for porting mobile numbers. For all other number types you may disregard this requirement.
  2. Number gets approved by Twilio. If everything in Step 1 was done correctly, you can expect Twilio to approve your port request in 24 hours. 
  3. Number is Submitted to Carrier Partner. This can take up to 24 hours. Your request is then submitted to your soon-to-be former carrier as a port request. During this time, do not close your account with your carrier and keep your numbers active.
  4. Carrier Partner reaches out to Losing Carrier. This can take one (1) week to complete.
  5. Response from carrier. At this point, your request will either be approved or rejected:
    • Approved: If approved, then you will receive a porting date of when your number will ported to Twilio.
    • Rejected: Rejections can occur for a variety of reasons, such as an incorrect PIN for an account, an address or zip code that doesn’t match the current carrier’s record, or a port request made by an unauthorized user on the account. Read more about common reasons for port request rejections here. Additionally, you will likely need to reach out to your losing carrier to find out what’s needed to move forward. Depending on the needs of the carrier, this will add an undetermined amount of time to your porting request.
  6. Twilio reaches out to you with your porting date. Twilio will send you an email of your porting date for when your number will be transfer to Twilio. Once your date has passed and you’ve verified the number has transferred to your Twilio project, you can begin using your number. Please configure your voice and SMS URL’s at this time.
  7. Configure Voice URLs. It is critical to set up the URL in advance of the port date so that everything is ready for when traffic ports over to Twilio.

We charge a one time port-in fee for the United Kingdom, for more details please reach out to porting@twilio.com.
