Transfer A Phone Number From O2 to Vodafone: Step-By-Step Instructions
Switching from O2 to Vodafone? It's a straightforward process to keep your existing phone number.
Step 1: Obtain a PAC Code from O2
The first step is to contact O2 to obtain your Porting Authorisation Code (PAC Code).
If you're a Pay Monthly customer on O2, you can request a PAC Code by calling 202 on your O2 handset. Alternatively, dial 0344 8090202 from any other phone.
Alternatively, if you're a Pay As You Go customer on O2, request a PAC Code by calling 4445 on your O2 Pay As You Go handset. You can also call 0344 8090222 from any other phone.
You can request a PAC Code over the phone at any time during O2's opening hours:
|Monday - Friday||8.00am - 9.00pm|
|Saturday||8.00am - 8.00pm|
|Sunday||8.00am - 6.00pm|
- A PAC Code is 9 digits long and follows the format ABC 123 456.
- O2 must provide a PAC code within 2 hours of your request. If they don't, they must provide a valid reason for why the PAC Code can't be issued. Your right to a PAC code is enshrined within Ofcom's "General Conditions of Entitlement" (May 2015, clause 18).
- 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 end automatically when your phone number is transferred to Vodafone.
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.
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 you need to return/replace the new phone or SIM card, please do this before the phone number transfer.
Once you're happy to continue with the phone number transfer, contact Vodafone and provide them with your PAC Code.
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.
- 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 5.00pm, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays). After 5.00pm, 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.
