This article explains how to submit a number porting request for UK mobile numbers directly from the Aircall Dashboard. The process is self-service and completed in a few steps. Porting a UK number typically takes up to 6 weeks after your documentation is validated.

What is number porting?

Number porting allows you to transfer your existing phone numbers from another carrier to Aircall without changing the numbers. Your team and customers continue using the same numbers while benefiting from Aircall features.

Before you start

Preparing accurate information is essential. Missing or incorrect details are the most common cause of delays or rejections.

Get your PAC

A Porting Authorisation Code (PAC) is required to port a UK mobile number. Request it from your current provider before you start. Without it, the port cannot proceed. You can request your PAC by texting “PAC” to 65075 or by contacting your current provider directly. Your PAC remains valid for 30 days before it expires.

For the full list of documents and information required for UK mobile numbers, see Number porting requirements by country.
