Mexico's other credit bureau, owned by Banco Azteca, Famsa and Coppel. It leans heavier on retail accounts and on customers without a formal banking history. Your score can differ between Buró and Círculo because they share information but process it differently.
Mexico runs two credit bureaus in parallel: Buró de Crédito (the original, 1996) and Círculo de Crédito (newer, 2005). The same banks and SOFOMs report to both, so what appears on one usually appears on the other. Small gaps happen — a fintech might report to Círculo but not Buró, or vice versa.
You can pull your report free once per year from each bureau: circulodecredito.com.mx and burodecredito.com.mx (the Reporte de Crédito Especial route in both cases). Score differences between the two are typically minor (10-30 points), because both use similar FICO-derived models. If a lender rejects you and you dispute the data, file the correction with the specific bureau that carries the wrong record — the fix doesn't automatically propagate to the other one.
