How to change your name with Prosperity Bank
Married or divorced and updating your accounts? Here's how Prosperity Bank takes a name change, from its own help page.
In person or by phone only. Prosperity Bank is one of the few that won't change your name online. Call 1-800-531-1401 or visit, and bring your documents.
Prosperity Bank's steps
Prosperity doesn't post online steps for a name change. Call or visit your banking center and ask what they need; bring your certificate or decree and new ID.
Have these ready
- A copy of your marriage certificate, divorce decree or court order (most companies ask for one).
- Your updated driver's license or ID, if you have it. Social Security comes first, then the DMV.
- Your account number, and the name the account is in now.
Let Sasha handle the letters
Sasha writes and signs your name change letter for Prosperity Bank and every other company on your list, with your certificate attached. It also keeps track of who's done. The checklist is free.
