Which Credit Bureau Does American Express Use?

American Express almost always checks Experian. In SmartDispute’s data, 74 of 75 American Express hard inquiries appeared on Experian. Only one appeared on TransUnion, and none appeared on Equifax.

That makes Amex one of the most predictable lenders on a credit report. If you applied for an Amex card, look for the inquiry on your Experian report, listed as AMEX or AMERICAN EXPRESS. This guide explains what the data shows, how Amex’s application check works, and what to do if you see an Amex inquiry you don’t recognize.

Which Credit Bureau Does American Express Use?

American Express doesn’t publish which bureau it checks for a given application. But SmartDispute’s de-identified data on 14,326 hard inquiries from 590 members, who each had reports from all three bureaus (inquiries dated January 2023 through September 2026), shows an unusually clear pattern:

A few other patterns stand out:

• One application, one report. Of the 63 members with an Amex inquiry, 62 saw it on only one report.
• Few lenders are this consistent. Among lenders that appeared for at least 40 members, only 700Credit, USAA, and Credit Acceptance relied on Experian as completely.
• It’s the opposite of Capital One, which usually checks all three bureaus for one application.
• About one in nine members had at least one American Express inquiry.

These are patterns, not rules. American Express can check other bureaus, and your own reports are the only reliable record of where an inquiry appears.

How American Express Appears on Your Credit Report

Amex inquiries are easy to recognize. These are the names that appeared in SmartDispute’s data:

American Express issues its own cards, so you won’t see a store name attached the way you do with Synchrony or Citi store cards. Co-branded Amex cards, such as Delta, Hilton, and Marriott cards, still appear under the American Express name.

Apply With Confidence: When Amex Uses a Soft Inquiry

American Express offers a tool called Apply with Confidence. According to American Express, it uses a soft credit inquiry to show whether you’d be approved for a card before you commit. Checking won’t affect your score. If you then accept the card, Amex may make a hard inquiry.

That has two practical effects:

• An Amex check you did to see your odds shouldn’t appear as a hard inquiry. It’s a soft inquiry, visible only on your own copy of your report.
• A hard Amex inquiry usually means a card was actually applied for and accepted.

If your Experian report is frozen, Amex likely can’t complete the check. Lift the freeze before you apply, or the application may stall. Our guide to credit freezes explains how freezes work.

Is an Amex Inquiry Legitimate?

Usually, yes. A hard inquiry from AMEX normally means you applied for an American Express card or business credit. Applying gives American Express a permissible purpose to check your credit.

Not every Amex credit check is a hard inquiry. Apply with Confidence checks are soft, and if you already have an Amex card, American Express may review your report to manage the account. Those account reviews are also soft inquiries and don’t affect your score.

An Amex hard inquiry deserves a closer look when:

• You don’t remember applying for any American Express card around that date.
• It appears on Equifax or TransUnion, but you only remember a single application. That’s unusual for Amex, so check whether it’s a second application or someone else’s.
• The same inquiry appears more than once on the same bureau, on different dates, for one application.
• You believe someone may have applied in your name.

How to Dispute an Amex Inquiry

Inquiries follow a different order than other credit report disputes. Start with American Express, then involve the credit bureau, which for Amex is almost always Experian.

1. Write to American Express first. Send your letter to the address Experian lists with the inquiry on your credit report. Ask American Express to identify the application behind the inquiry and the permissible purpose it relied on. Don’t include ID or your Social Security number.
2. Wait 35 days from the date you mailed it.
3. Dispute with the credit bureau reporting the inquiry if American Express doesn’t respond or can’t connect the inquiry to you. Attach a copy of your letter to American Express as an exhibit.
4. Follow up if the bureau’s result comes back “verified” without addressing why American Express pulled your report.

The letters for each step are in Free Inquiry Dispute Letters That Work, and we explain why this order works in How to Remove Hard Inquiries From Your Credit Report.

If you’re certain the inquiry came from identity theft, there’s a faster route: an identity theft report and a block under Section 605B of the FCRA, which we cover in our guide to permissible purpose.

How to Dispute an Amex Account

If an American Express account on your report has incorrect information, the approach is different from an inquiry: dispute with American Express and with each credit bureau reporting the error at the same time. Amex reports its accounts to the bureaus even though it usually checks only Experian when you apply.

Check these details against your own statements and records:

• Payment history: late payments that don’t match your records, or late payments reported after the account was closed or paid off.
• Balance and credit limit: a balance reported after you paid the card off. Some Amex cards have no preset spending limit, so check how the limit is reported.
• Dates: the date opened, date closed, and date of first delinquency. An incorrect date of first delinquency can change how long a negative item stays on your report.
• Authorized-user accounts: an account where you were an authorized user, still reporting after you were removed.

When you dispute, identify the account (a partial account number is enough), state exactly what is wrong, say what the correct information is, and include copies of the statements or letters that support it.

American Express Contact Information

Disputes about credit reporting are best handled in writing. A letter creates a record of what you asked and when, which a phone call doesn’t.

Frequently Asked Questions About American Express

Which credit bureau does American Express use?

Almost always Experian. In SmartDispute’s data, 74 of 75 American Express inquiries appeared on Experian, one on TransUnion, and none on Equifax.

Does American Express do a hard pull?

For a card you apply for and accept, yes, usually on Experian. Amex’s Apply with Confidence tool uses a soft inquiry first, so checking whether you’d be approved doesn’t affect your score.

What is AMEX on my credit report?

American Express. An AMEX inquiry means American Express checked your credit, usually for a card application. An AMEX account is an American Express card.

What is AMERICAN EXPRESS KABBA on my credit report?

American Express’s business line of credit, previously called Kabbage. It appears if you applied for that line of credit for a business.

Can I remove an Amex inquiry from my credit report?

A legitimate inquiry generally stays on your report. Hard inquiries remain for up to two years, and FICO counts them for only 12 months. If the inquiry can’t be connected to an application you made, you have the right to dispute it, starting with American Express.

The Bottom Line

American Express is one of the most predictable names on a credit report: one application, one inquiry, almost always on Experian.

When an Amex inquiry doesn’t make sense, ask American Express first and take the answer to Experian. For an account with errors, dispute with American Express and the bureau together, with your records in hand.
