How do I keep my mobile phone number?

Posted on 11 Jun 2014

How do I keep my mobile phone number?

Here is everything you need to know about keeping your number when you change your contract or SIM card.

What do I need?

You'll need a PAC (Porting Authorisation Code). This is a code that lets you transfer your current number to your new SIM card. You need to get this from your current network.

Do I always need a PAC?

No, not always.

If you're staying with your current network, you'll need a PAC if you're upgrading from a Pay as you go deal to a Pay Monthly one. If you're upgrading from one Pay monthly contract to another, or upgrading from a Pay as you go phone to another, you don't need a PAC. Your number will automatically be put onto your new SIM.

If you're moving from one network to another, you'll need a PAC.

How do I get a PAC?

Call your current network and ask for your PAC. It's free to get your PAC, and your network has to give you one within two days, or tell you why they can't.

You need to get your PAC before you disconnect your old SIM. If you don't, you won't be able to transfer your number.

How do I use my PAC to make sure my number is transferred?

When you're buying your new deal, give your PAC code to us at the checkout, either online, over the phone or in store. Your PAC is valid for 30 days, so you have plenty of time to use it, but try to use your PAC as soon as possible. If you're getting a Virgin deal you need to transfer your old number after you've been connected. To do this, call Virgin and give them your PAC.

Can I use a PAC after I've bought my new deal?

Yes, you can, but not if you've bought a deal from Talkmobile as the PAC needs to be used at the checkout for this network.

For all other networks, call them up with your PAC code and they'll be able to transfer your number to your new deal. Make sure you contact them before your SIM has been disconnected.

How long will it take to transfer my number?

Two working days. If you give your PAC code to Carphone Warehouse, we'll transfer your number within 2 working days of your new phone being connected. If you give your PAC code to your network, the amount of time it takes to transfer your number can vary.
