How do I change address in My O2?

Once you’ve signed in to My O2, click on ‘Manage my details’. We’ll send you a one-time activation code so you can view and edit your details.


If you’ve chosen a third party to manage your bills, you’ll now also see their details in the address section.


If you’ve been with us for more than 90 days, you can enter an alternative delivery address when it’s time for your sim swap. Just make sure you sign in to My O2 first.


Can I change my account address to an international address?

To change your address to an international, PO Box or BFPO mailing address, please get in touch directly.


If you change your UK address on your O2 account to an overseas address, there are many actions you’ll no longer be able to do. This includes re-signing your contract, upgrading your device, adding a new connection like a tablet or smartwatch, replacing your sim, and returning/replacing your device.


If you haven't already, we recommend that you register for My O2 to manage your account, and set up a Direct Debit to pay your bills.


What happens next?


Once you contact us, a ticket will be raised on your account, and you’ll be required to send a copy of one of the following documents showing your new address:


  • Utility bill
  • Bank/Credit Card statement
  • Mortgage/Rental statement
  • Council tax bill
  • Benefits statement
  • Driving licence

Things to note:

  •  The document must be dated within the last three months and must show your full name and new address.
  • The ticket will stay open for 30 days. And, if the relevant documents aren't received within these 30 days, then the ticket will be closed and no update will be made to your address.

You can upload your documents on My O2 or send it to us in the post at:
