Mexico

Mexico eKYB Verification validates the legitimacy of Mexican businesses by checking their tax ID, business name, and address against Mexican government sources of truth.

Mexico eKYB Verification is available in two modes:

  • Standard: Full verification of business name, address, and tax ID.
  • Lite: Reduced verification limited to business name, tax ID, and postal code.

UBOs and directors are not currently supported for Mexico Verification in any mode.

Info

For enrichment via lookup rather than field-by-field verification, see Mexico Prefill.

{/* TODO: Confirm with PM — how the API distinguishes between Standard and Lite mode requests. The endpoint, country, and taxId are the same; only the presence or absence of the additional address fields appears to differ. */}

Tax ID formats

RFC (Registro Federal de Contribuyentes) is the Mexican federal tax identifier.

Entity Type Format
Individual 13 characters: 4 letters + 6 numbers + 3 alphanumeric characters
Business 12 characters: 3 letters + 6 numbers + 3 alphanumeric characters

{/* TODO: Confirm with PM — the old docs conflated RFC with CURP in one callout. RFC and CURP are distinct Mexican identifiers. This page documents RFC only; confirm whether CURP is also accepted. */}
