Number of established accounts
Your file has few accounts with real age behind them. The model wants more accounts that have been open and reporting long enough to count as established, and a thin file falls short.
FICO code numbers
| Where you see it | Code |
|---|---|
| FICO (Equifax) | 28 |
| FICO (TransUnion) | 28 |
Code numbers can differ by bureau and score version. The wording of the statement is what to match.
What puts this reason on your score
This code appears on Equifax and TransUnion FICO Scores. In FICO's list, Experian's entry is marked for industry scores only. It's common on thin files, such as one card and one student loan, or a file rebuilding after old accounts dropped off.
More aged accounts give the model more evidence to work with. FICO doesn't publish what counts as established, so think of it as accounts with a solid run of reporting behind them, measured in years rather than months.
What to check on your credit report
- Count accounts that have been open and reporting for years, not months.
- Check that old accounts in good standing still show on each report.
- See whether the accounts you hold report to Equifax and TransUnion.
What you can do about it
- Add accounts gradually and keep them open.
- Ask a family member with a long-held, well-paid card about adding you as an authorized user, if the issuer reports authorized users.
- Use credit-building products that report to all three bureaus.

How soon a change can show
Slow. A new account needs time to count as established, so this code eases over months and years.
If you are applying for a mortgage
When this code ranks high, extra months of history help more than any quick move. Plan your timeline backward from the date you want to buy.
