Authorized user tradelines

When someone adds you as an authorized user (AU) on their credit card or loan, the account begins reporting on your credit file as well as theirs — even though you have no legal liability for the debt.

How AU reporting works

The primary holder applies, the primary holder owes the balance, but the bureau reports the tradeline on both files: theirs and yours. You inherit the account's full history — open date, payment history, balance, utilization. The good and the bad.

This is why "authorized user" arrangements between parents and kids have historically been a common credit-building tool. A parent's 20-year-old card with perfect history adds 20 years of average account age and a thick payment-history grid to a kid's otherwise thin file.

When AU helps

• Long-running, never-late, low-utilization account: pure positive.
• Builds account age, especially helpful for thin files.
• Adds a tradeline category you don't otherwise have (e.g., revolving credit on a file with only installment loans).

When AU hurts

• The primary holder runs up a high balance: utilization on the AU account dings your score even though you don't owe the debt.
• The primary holder misses payments: the late mark reports on your file too.
• The primary holder closes the account: average account age can drop sharply once the closed account ages out.
• The primary holder defaults: a charge-off on the original account drags your file even though you weren't a borrower.

If any of those is happening on an account you're an AU on, the relationship has flipped from helpful to harmful and you should probably remove yourself.

How to remove yourself as AU

Two paths, and you should generally do both:

1. Ask the primary holder to remove you. They contact the issuer and request it. The issuer updates internal records and stops reporting the AU relationship to the bureaus.
2. Contact each bureau directly. Even after the issuer removes you, the historical AU tradeline often stays on your report. Under FCRA you can request removal from your file directly — you're not the borrower, and you have the right to have the tradeline removed from your report.

"Credit piggybacking" caveat

There's a small industry that sells AU tradeline rentals — pay a fee, get added as an AU on a stranger's seasoned card for 60 days, inherit the history. Two warnings:

• FICO 8 and FICO 9 weight AU tradelines from non-relatives less than from related parties. The score lift may be smaller than advertised.
• Lenders increasingly look askance at sudden AU additions during underwriting. Some manually remove AU tradelines when reviewing applications.

Stick to AU arrangements with people you actually have a relationship with.

When to dispute an AU tradeline

When it's reporting incorrectly:

• You were added but never authorized.
• The account ended but is still reporting as active on your file.
• The account has wrong dates, wrong balances, or wrong status.
• The primary holder is your ex-spouse and they retained the account in the divorce decree but the AU tradeline is still on your file.

Each of those is a §611 dispute. The relationship documentation — divorce decree, written request to the issuer, etc. — strengthens the dispute.
