How to Get a PAC Code from Three

Your Three PAC (Porting Authorisation Code) is the code that moves your Three number to another network. Under Ofcom's text-to-switch rules, Three must give it to you instantly and free — no retention calls, no charges on rolling plans.

All 3 ways to get your Three PAC code

1. Text PAC to 65075 (fastest)

The universal Ofcom switching service. Send "PAC" to 65075 from the Three number you want to keep — the code arrives by return text in under a minute. Works for contract and PAYG customers alike.

2. Three app

Open the Three app → Account → look for "Leave Three" or the switching section. Your PAC displays instantly with any early termination fee shown if you're still in contract.

3. Call Three

Call 333 free from your Three phone, or 0333 338 1001 from another phone. Expect security checks — texting is faster.

What happens after you get the code

• Your PAC is valid for 30 days — request a new one if it expires.
• Give it to your new network when activating their SIM. The number transfers within one working day.
• Your Three account and billing end automatically when the transfer completes — no separate cancellation needed on rolling plans.
• On a fixed-term contract, remaining months may be charged — check the info text that arrives with your PAC.

Leaving Three? Cheaper rolling plans on Three and Vodafone

Three's pay-monthly prices have climbed — but Giffgaff (Three) and Lebara (Vodafone) both offer 30-day plans from around £5-£6/month with no contract and no credit check. Check coverage at your postcode first, then hand your Three PAC to whichever fits.

Three PAC code problems?

• No text back? Check you sent it from the Three SIM itself, not another phone. Try 202 if texting fails.
• Code expired? Just text PAC to 65075 again — fresh codes are instant.
• Transfer didn't complete? PACs only process on working days — requests over the weekend complete Monday/Tuesday.
