Who reports and what is reported
In Mexico, credit information companies (SICs, by their Spanish initials) operate under the Law Regulating Credit Information Companies — the well-known Buró de Crédito (Mexico's credit bureau) and Círculo de Crédito. Banks, SOFOMs (non-bank lenders), department stores, telecom carriers, and other creditors report every month on how you pay: balance, limit, late payments. There is no "blacklist" — just the movie of your payments, good or bad.
How long a late payment lives in your record
The general rule of art. 23 of the LRSIC: SICs keep credit histories for at least 72 months, and must remove default information after 72 months counted from when the first default was recorded. For small debts the periods are shorter (measured in UDIS, Mexico's inflation-indexed units): for the very small ones — up to 25 UDIS — it is about a year; up to 500 UDIS, two years; up to 1,000 UDIS, four. Two exceptions worth knowing: loans for very high amounts and cases involving fraud are not eligible for removal.
The practical upshot: a stumble does not mark you for life, but it also does not disappear "in three months" as some out there promise. And note: being removed from the bureau does not mean the debt no longer exists — the collection action is a separate matter, with its own statute-of-limitations periods.
Your free report (and the score)
You are entitled to a free Special Credit Report every 12 months; request it directly from the SIC. Review it at least once a year: creditor errors, accounts you don't recognize, and unauthorized inquiries are disputed in writing with the SIC itself, which is required to process your dispute. The "score" is a statistical summary of your history: it improves with on-time payments, moderate use of available credit, and account age; it worsens with late payments and maxed-out cards.
Building a record from scratch
- Start small: a department-store or secured card, a phone plan.
- Set up direct debit: your history rewards boring punctuality, not amounts.
- Use <50% of your limit consistently; chronically maxing out is penalized.
- Don't open five products in a month: a burst of inquiries reads as urgency.
What if my bureau is battered and I need liquidity?
This is where credit with real collateral changes the game: the backing shifts part of the analysis from your record to the asset. A bad bureau makes unsecured credit more expensive or closes it off; with ample collateral, the conversation stays open — that's how we operate at Tunton. There is no magic, though: anyone who offers to "erase the bureau" for a fee is selling snake oil, and CONDUSEF (Mexico's financial consumer protection agency) periodically warns against those scams.
