Who reports and what is reported
In Mexico, credit information companies (SIC) operate under the Law Regulating Credit Information Companies — the well-known Buró de Crédito (Mexico's credit bureau) and Círculo de Crédito. Banks, SOFOMES, department stores, telecom carriers and other lenders report every month how you pay: balance, limit, late payments. There is no "blacklist": there is your payment movie, good or bad.
How long a late payment lives in your record
The general rule of art. 23 of the LRSIC: SIC keep credit histories for at least 72 months, and must remove default information after 72 months from the recording of the first default. For small debts there are shorter periods (in UDIS): the very small ones —up to 25 UDIS— run around a year; up to 500 UDIS, two years; up to 1,000 UDIS, four. Two exceptions worth knowing: very high-amount credits and cases involving fraud do not benefit from removal.
Practical translation: a stumble does not mark you for life, but it also does not disappear "in three months" as some promise out there. And note: removed from the bureau does not mean the debt ceased to exist — 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, by requesting 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 before the SIC itself, which is required to process your claim. 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 store or secured card, a phone plan.
- Set up direct debit: the record rewards boring punctuality, not amounts.
- Use <50% of your limit consistently; chronic overdraft 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 shuts it off; with ample collateral, the conversation stays open — that's how we operate at Tunton. What does not exist is magic: anyone who offers to "erase the bureau" for a fee is selling smoke, and CONDUSEF (Mexico's financial consumer protection agency) periodically warns against those scams.
