Switching mobile network? How to keep your number with a PAC
In short
- Text PAC to 65075 and your provider must reply within a minute with your code. The text is free and the code lasts 30 days.
- Give the PAC to your new provider, which must switch you within one working day. Your codes keep coming, as the number stays the same.
- Getting a new number instead? Text STAC to 75075, and move your accounts to the new number before the old one goes.
In the UK you can take your mobile number with you when you change network, and Ofcom’s rules make it quick.
Get your PAC
Text PAC to 65075 from the phone. Your provider must reply within a minute with your Porting Authorisation Code and important details, such as any early termination charges or pay-as-you-go credit left. The text is free, and the code is valid for 30 days. To check what you’d owe without asking for a code, text INFO to 85075.
Give it to your new provider
Your new provider must complete the switch within one working day, and any loss of service mustn’t last longer than that. Your old provider can’t charge you for a notice period after the switch date. Ofcom says that if the switch takes longer than one working day, you’re entitled to reasonable compensation from your provider.
What happens to your verification codes
The number moves with you, so every app that texts it keeps working. Codes go to the old SIM until the switch completes, so keep it to hand on the day.
Changing number instead
Text STAC to 75075 for a Service Termination Authorisation Code, to leave without your number. Move your accounts to the new number first, as many apps text the old one before they’ll change it: see changing your phone number. Your old number can later go to someone else: see recycled phone numbers.
Number theft
Criminals sometimes try to take over a victim’s number to receive their codes. See SIM swap fraud.
