Changing your name

Need to change your name on your O2 account? Fill in this form with the details of all the account numbers you have with us. And make sure you include a copy of one of these documents:

  • Marriage certificate
  • Certificate of civil partnership
  • Deed poll
  • Reissued birth certificate showing your old and new name (only in Scotland)

Once you’ve got all this together, send it to this address:

If you’d rather email us, scan your documents and send them to BusinessTOO@o2.com.

Or you can fax them to 0870 600 2402.

Once we’ve received your documents, we’ll update your details within five working days. And we’ll get in touch to let you know when we’ve done this.
