Switching from O2 to Vodafone? It's a straightforward process to keep your existing phone number.

Step 1: Get a PAC Code from O2

If you’d like to move your phone number from O2 to Vodafone, the first step is getting your Porting Authorisation Code (or PAC Code) from O2.

There are three ways to get a PAC Code from O2:

  1. Online: You can get a PAC Code from O2 by logging in to the My O2 website. Once you've logged in, go to My details > Thinking of switching from O2?.
  2. By Text Message: You can get an O2 PAC Code sent to you via SMS text message. Text PAC to 65075 to receive a PAC Code from O2.
  3. By Phone: You can get a PAC Code by calling O2. To do this, call them on:
    • For O2 Pay Monthly, dial 202 (or 0344 8090202 from any other phone)
    • For O2 Pay As You Go, dial 4445 (or 0344 8090222 from any other phone)
    You'll need to call during O2's opening hours (Monday-Friday 8am-9pm, Saturday 8am-8pm, Sunday 8am-6pm).

Here are some key things to know:

  • The PAC Code from O2 should consist of six numbers with TEL at the start (e.g. TEL 123 456).
  • Your PAC Code is valid for 30 days. If you don't use it during this time, the PAC Code will expire and you'll need to request a new one.
  • You shouldn't close your account at O2: it'll be closed automatically when your phone number is transferred to Vodafone.

Still in contract with O2? If so, you may need to pay an early exit fee on your bill from O2. To find out how much this would be, text INFO to 87075.

Don’t want to keep your O2 phone number? You can switch to Vodafone without taking your phone number with you. If you'd like to do this, get a STAC Code from O2 instead.

O2 STAC Code (Leave O2 Without Keeping Your Number)

If you’d like to leave O2 without keeping your phone number, you’ll need to request a STAC Code rather than a PAC Code. There are three ways to get a STAC Code from O2:

  1. Online: You can get a STAC Code from O2 by logging in to the My O2 website. After logging in, go to My details > Thinking of switching from O2?.
  2. By Text Message: You can get an O2 STAC Code sent to you via SMS text message. Text STAC to 75075 to receive a STAC Code from O2.
  3. By Phone: You can get a STAC Code by calling O2. Call them on:
    • For O2 Pay Monthly, dial 202 (or 0344 8090202 from any other phone)
    • For O2 Pay As You Go, dial 4445 (or 0344 8090222 from any other phone)
    You'll need to call during O2's opening hours (Monday-Friday 8am-9pm, Saturday 8am-8pm, Sunday 8am-6pm).

Once you’ve gotten your STAC Code from O2, the rest of the process for joining Vodafone remains the same.

Step 2: Order your new phone or SIM card from Vodafone's website

You should now order your new phone or SIM card using the Vodafone website. Please select the type of tariff you're intending to move to:

For a full list of available tariffs and the latest Vodafone deals, please refer to this page on Vodafone's website.

Alternatively, if you're getting your Vodafone plan from a reseller, tap on their logo for more information:

Vodafone will assign you with a temporary phone number during the transition process. This will allow you to test out the service before you finally transfer your phone number to Vodafone.

Step 3: Give the PAC Code to Vodafone

Once your new phone or SIM card arrives from Vodafone, switch it on and make sure everything's working properly. If, for whatever reason, you need to return or change the handset or SIM card, it's best to do this before transferring your phone number.

Once you're happy to continue with the phone number transfer, contact Vodafone and provide them with your PAC Code from O2.

Your PAC Code should be entered on Vodafone's online form. Alternatively, you can give the PAC Code to Vodafone by calling 191 on your Vodafone handset. You can also call 03333 040 191 from any other phone.

If you have a STAC Code from O2 rather than a PAC Code, this can be provided to Vodafone in the exact same way.

Providing your PAC Code to Vodafone
The PAC Code should be submitted through a form on Vodafone's website.

Remember:

  • You must provide the PAC Code to Vodafone within 30 days of it being issued by O2. If the PAC Code has already expired, you'll need to return to step 1 and request a new PAC Code from O2.
  • O2 Pay As You Go customers: Try to use up your remaining credit as it can't be transferred to Vodafone.

Step 4: Phone Number Transferred (Next Working Day)

As long as you've submitted your PAC Code to Vodafone before 5pm, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays). After 5pm, you'll need to wait one extra working day for your number to be transferred.

On the day of the transfer, you'll momentarily lose coverage on both mobile networks. When this happens, restart your handset on Vodafone. You should find that the Vodafone phone or SIM card will now associated with your original phone number.

  • If you see an error message (e.g. "SIM card registration failed"), this means it's time to restart your phone.
  • Once the phone number has been transferred to Vodafone, your account on O2 will automatically be closed. You'll receive a final bill from O2 for any outstanding charges.

    I have bought my new phone from Vodafone am leaving O2. I have got the pac code but I want to tell O2 I’m leaving – how do I do that

    • Hi Loraine,
      Thanks for your comment. There’s no additional need to tell O2 that you’re leaving their network – simply asking for a PAC Code and using it provides your notice for leaving O2.
      Hope this helps,
      Ken

    I have 2 phones, one on Vodafone, 1 year in and 1 on O2, contract has lapsed, so free to end.

    Trouble is my O2 phone number is my primary number, so the question is can I port this number to my 2 year Vodafone contract phone as my primary number ?, replacing the Vodafone number mid contract ?

  • Hi I transferred from 02 to vodaphone today and although I can send & receive texts, I cannot receive calls! Very frustrating please help!

    • Hi Lorraine,
      Sorry to hear about the problems after transferring your phone number from O2 to Vodafone. It’s very strange you’re able to receive incoming text messages but not incoming phone calls (normally, if there’s a problem with the porting, both things should be affected at the same time). Either way, your best bet would probably be to talk to Vodafone Customer Services – you can reach them on 191 (or 03333 040 191 from a non-Vodafone handset).
      Ken
