For AML, use fuzzy name matching with a confidence score rather than exact match — accents and abbreviations cause a lot of false negatives. Most RFC tax identification APIs return raw registered name; matching logic is on you.

Our compliance team needs an RFC tax identification API to cross-reference client-provided tax info against SAT's official records. This is for AML compliance — we need to confirm the RFC matches the expected taxpayer name before processing transactions above a certain threshold.
I've been looking at different providers but they vary a lot in what data they return. Some give full fiscal profile, others just valid/invalid. For AML purposes we specifically need: the registered taxpayer name, RFC issue date, and any sanction flags from SAT.
What RFC tax identification API are people using for AML workflows? And how do you handle discrepancies between the user-provided name and the SAT-registered name?
