Credit score reason codes, in plain English

Every credit score comes with up to four or five short reasons that say what held it back. Find yours below. Each page says what it means, what to look for on your report and what you can do.

The full explanation of how reason codes work is in credit score reason codes, decoded.

FICO reason codes

FICO reason codes, also called key factors, are the short statements that come with a FICO Score and list what held it back the most, in order. Equifax, Experian and TransUnion each produce their own FICO Score, so a mortgage file carries three sets, and a few statements use a different code number at each bureau. The numbers here come from FICO's published U.S. reason code list, revised June 2025.

VantageScore reason codes

VantageScore reason codes are the short statements printed with a VantageScore that list what held it back the most, in order, with up to four reasons plus a fifth when inquiries played a part. VantageScore 4.0 and 3.0 use different numbered lists, so the same problem can carry two different numbers, and some numbers mean different things in each version. Match the wording first, then check which version is printed next to your score.
