The only personal information you can’t change in the Three app or online is your name. If you need to change the name on your account because you’ve married, divorced, or changed your name by Deed Poll, write to us with proof of the name change.
All we need is one of the following pieces of information:
- A copy of your marriage or civil partnership certificate. If you don’t have one, a copy of your passport and a recent utility bill is also acceptable.
- A copy of a Deed Poll.
- A copy of the decree absolute - if you’re divorced and want to use your maiden name.
Remember, we only need one of the above, and not all three!
One more thing. When you do write to us, remember to include a cover letter requesting that your name be changed.
