How to Get Your PAC Code from O2

3 Ways to Get Your PAC Code from O2

O2 must provide your PAC code free of charge under Ofcom regulations. Here are the three methods, ranked by speed:

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

Send a text message with the word PAC to 65075 from your O2 mobile. O2 will reply within 60 seconds with your 9-character PAC code and any early termination charges that apply. This is the method mandated by Ofcom and works on all UK networks.

This is the recommended method because it avoids any retention calls and gives you the code instantly.

2. Call O2 Customer Services

Call 202 from your O2 phone (free) or 0344 809 0202 from any other phone. Ask the agent for your PAC code. They may offer you a retention deal to stay — you are under no obligation to accept. The agent must provide your PAC during the call.

O2 customer services are available Monday to Friday 8am–8pm, Saturday 8am–6pm, and Sunday 8am–6pm.

3. Request Online via My O2

Log in to the My O2 app or visit o2.co.uk. Navigate to account settings or the "Leaving O2" section to request your PAC code online. You can also use the O2 online chat to request your PAC if you prefer not to call.

What Happens After You Get Your O2 PAC Code

1. Give the PAC to your new provider — they will start the porting process on your behalf.
2. Your number transfers within 1 working day — you can keep using your O2 SIM until the port completes.
3. Your O2 SIM stops working — once the port is complete, your old SIM is deactivated automatically.
4. Your O2 contract is cancelled automatically — you do not need to contact O2 separately to cancel.

How Long Is an O2 PAC Code Valid?

Your O2 PAC code is valid for 30 days from the date it is issued. If it expires before you use it, simply request a new one for free using any of the methods above. Requesting a PAC does not cancel your contract — it only starts the switching process when you give it to your new provider.

Can I Keep My O2 Number?

Yes. That is exactly what a PAC code is for. When you give your PAC to your new network, your existing O2 number transfers to the new SIM. There is no gap in service — your number moves across within 1 working day and you keep the same number you have always had.

Things to Check Before Switching from O2

• Contract status — if you are still within your minimum term, early termination charges may apply. O2 will tell you the exact amount when you request your PAC.
• Outstanding device payments — if you bought a phone on O2 Refresh, any remaining device plan balance will need to be paid.
• O2 Priority perks — you will lose access to O2 Priority rewards and offers once you leave.
• Data and services — download any voicemails or data you want to keep before the switch completes.
• Business accounts — if you have an O2 business account, the account holder may need to authorise the PAC request.

O2 PAC Code vs STAC Code

If you want to leave O2 but do not want to keep your number, you need a STAC (Service Termination Authorisation Code) instead. Text STAC to 65075 to get one. A STAC simply ends your contract without porting your number.
