Mexico AML API for sanctions and PEP screening?
Question
Answers
SAT 69-B updates in batches, typically monthly. Best Mexico AML API providers sync within 24h of each SAT publication. For Mexico PEP data specifically, coverage varies widely — ask providers for their source list.
69-B Bis is the one most teams miss on their first pass — you're right to ask separately. Not every Mexico AML API bundles it automatically, so confirm that explicitly with the provider rather than assuming coverage. On false positives: fuzzy name matching against PEP lists is genuinely rough for common Mexican surnames unless the provider also matches on CURP or date of birth as a secondary field. Ask for a provider that supports match confidence scoring rather than a flat yes/no — that alone cut our manual review queue by more than half, since we could auto-clear anything below a certain confidence threshold instead of reviewing every Hernandez that came through.
One more thing worth budgeting for: ongoing monitoring, not just onboarding-time screening. Regulators generally expect re-screening against updated lists on some cadence, so factor that into whichever provider's pricing model you pick rather than treating it as a one-time check.
I'm building AML screening into our payments platform and need a Mexico AML API that covers: SAT 69-B list (fake invoice issuers), OFAC/UN sanctions, PEP screening for Mexico, and ideally some adverse media monitoring.
The main question is: how often are these lists updated in third-party Mexico AML APIs? SAT updates 69-B periodically but the exact cadence isn't clear. And for PEP screening, how comprehensive is Mexico-specific PEP data vs international lists?
We also need to screen against the 69-B Bis list, not just the main one — we're a factoring platform so we're exposed if a client accepted invoices from a blacklisted issuer, not just if the client is on the list themselves. Is that a separate integration or do most Mexico AML API providers bundle both lists by default? And practically speaking, what does a false-positive rate look like on PEP matching for common Mexican surnames — we're worried about flagging half our customer base named Hernandez or Garcia.
