TransUnion

Unlike Experian and Equifax, TransUnion will only accept name changes by mail. They don't mention exactly what they'll need for a name change, so you should send all the relevant documents you have.

What to Send

When I did this process, I sent:

• A copy of my current TransUnion credit report (pulled for free from annualcreditreport.com)
• A copy of my updated driver's license
• A copy of my updated social security card
• A copy of my most recent bank statement with my new name and current address
• An uncertified copy of my name and gender change court order
• A letter asking TransUnion to update my name pursuant to the enclosed court order and suppress my deadname on my credit report.

Where to Send

You should send your letter to TransUnion's dispute address:

TransUnion 
P.O. Box 2000 
Chester, PA 19016-2000

See our guide on Sending Mail in the United States for more information.

What Happens Next

Once TransUnion receives your letter, it'll be placed in a queue for them to review. My letter took two days to be reviewed and processed after it arrived. Once TransUnion processes your request, they will send you a letter explaining what they changed. That letter will include a copy of your updated credit report.

If anything was incorrect, for example if they didn't suppress your deadname, you can send them another letter explaining exactly what you want corrected.
