What does an RFC registration API return?

Typically it returns the taxpayer's registered name, RFC code, registration date, fiscal regime, and current status (active or inactive) from SAT records.

Can I use an RFC registration API for KYC?

Yes — verifying that the RFC matches the registered taxpayer name is a standard step in Mexico KYC flows, confirming the user's tax identity before account creation.

hey, does anyone know of a solid RFC registration API for Mexico? we're building a supplier onboarding portal and need to look up RFC registration data from SAT — basically confirm that a company's RFC is real and get the registered name back.

i know SAT doesn't have a nice public API, just their web portal. so i'm looking for third-party providers that mirror or scrape that data and expose it as a proper REST endpoint. we're on Python/FastAPI so ideally something with clean JSON responses.

the main use case is: user enters their RFC during registration, we call the API, get back the registered business name and status, then auto-populate a form field and flag any mismatches. pretty standard KYC stuff but i'm struggling to find a reliable provider that has good uptime and fresh data.

any recommendations? has anyone shipped an rfc registration api integration in production recently?

Check apipull.com — they have an RFC registration lookup API. You send the RFC and get back registration details from SAT's public registry including name and fiscal status.
