FICO score reason code · Code 12
“Length of time revolving accounts have been established” — Decoded.
That line on your denial letter isn’t an insult — it’s a standard reason code, and it’s telling you exactly which lever moved against you. Here’s what it actually says about your file, in plain English.

“Length of time revolving accounts have been established” means: Your credit card history specifically is young. It does not mean: You should close your oldest card to 'clean up' — a closed card keeps counting while it stays on your report, but once it falls off, the history it anchored goes with it. The 800 Club’s team turns this reason into a plan on a free strategy call.
