How to Get a PAC Code from Three

3 Ways to Get Your PAC Code from Three

Three must provide your PAC code free of charge under Ofcom regulations. Here are the ways to get it, ranked by speed:

1. Text PAC to 65075 (Fastest — 60 Seconds)

Send a text message with the word PAC to 65075 from your Three mobile. Three must reply within 60 seconds with your 9-character PAC code and any early termination charges that apply. This method is mandated by Ofcom and works on every UK network.

This is the recommended method — it is instant and avoids any retention calls.

2. Call Three Customer Services

Call 333 from your Three phone or 0333 338 1001 from any phone. Ask the agent for your PAC code. They may offer you a deal to stay — you are under no obligation to accept, and they must still provide your PAC during the call.

3. Request Online

Log in to My3 app or My3 online and request your PAC code from the account or "leaving Three" section. This is handy if you would rather not call.

What Happens After You Get Your Three PAC Code

1. Give the PAC to your new provider — they start the porting process for you.
2. Your number transfers within 1 working day — keep using your Three SIM until the port completes.
3. Your Three SIM stops working — once the port is done, your old SIM is deactivated automatically.
4. Your Three contract or plan ends automatically — you do not need to contact Three separately to cancel.

How Long Is a Three PAC Code Valid?

Your Three PAC code is valid for 30 days from the date it is issued. If it expires before you use it, request a new one for free. Requesting a PAC does not cancel your plan — it only starts the switch when you hand the code to your new provider.

Can I Keep My Three Number?

Yes — that is exactly what a PAC code is for. When you give your PAC to your new network, your existing Three number transfers to the new SIM with no gap in service. You keep the same number you have always had.

What Does a PAC Code Look Like?

A PAC code is nine characters — usually three letters followed by six numbers, for example ABC123456. The format is set by Ofcom and is identical on every UK network.

Things to Check Before Switching from Three

• Contract status — if you are still within your minimum term, early termination charges may apply. Three will tell you the amount when you request your PAC.
• Outstanding device payments — any remaining balance on a phone plan will need to be paid.
• Add-ons and perks — you will lose any included extras once you leave Three.
• Business accounts — if this is a business account, the account holder may need to authorise the PAC request.

Three PAC Code vs STAC Code

If you want to leave Three but do not want to keep your number, you need a STAC (Service Termination Authorisation Code) instead. Text STAC to 65075 to get one — it ends your contract without porting your number.
