Key facts

  • Postal disputes to TransUnion go to TransUnion, PO Box 647, Unit 4, Hull HU9 9QZ.
  • TransUnion must investigate a dispute and either correct the information, remove it, or explain why it stands, typically within 28 days.
  • If a lender won’t change a disputed entry and the agency agrees it can’t resolve it, you can require the agency to add a free Notice of Correction — a short statement in your own words attached to your file.
  • Disputing with one agency does not fix the other two. If the same error appears on all three reports, dispute with Experian, Equifax, and TransUnion separately.
  • PostPal’s dated confirmation of mailing gives you proof of when the agency received your letter — useful if you need to escalate to the Financial Ombudsman Service or the ICO.

How to send your letter

  1. 1

    Write a clear dispute letter

    State your full name, date of birth, and current address, identify each item you are disputing (lender name and account number), explain why it is wrong, and ask TransUnion to correct or remove it.

  2. 2

    Attach copies of your evidence

    Include copies of anything that supports your dispute — a settlement letter, a statement showing the correct balance, or evidence of fraud. Circle the disputed items on a copy of your credit report if you have one, and keep your originals.

    Send it without a printer

    Write your dispute in PostPal, attach your evidence as PDFs or photos, and we print, envelope, and post it for £4 — with a dated confirmation email as your proof of posting.

Common questions

What is the postal address to dispute a TransUnion credit report?

TransUnion, PO Box 647, Unit 4, Hull HU9 9QZ. Send a written dispute with copies of any supporting documents; TransUnion must investigate and respond, typically within 28 days.

Is it better to dispute by post or online?

Both trigger the same investigation, but posting a letter gives you a dated record of exactly what you sent and lets you include the wording and documents you want — which matters if you later need to escalate to the Financial Ombudsman Service.

What is a Notice of Correction?

A free, short statement (up to about 200 words) that you can add to your credit file if you disagree with an entry the agency can’t remove. Lenders must take it into account when they see your file. Ask the agency for one if your dispute isn’t resolved the way you’d like.

Do I need to dispute with all three UK credit reference agencies?

Only the agency you write to will investigate. If the same error is on more than one report, send a separate dispute to each of Experian, Equifax, and TransUnion.
