How documents combine

For each evidence area, this table shows whether the listed documents are alternatives (any one of) or a bundle (all required). The artifact-by-artifact lookup follows below.

Evidence area	Documents needed
Legal Registration	All required: Acta Constitutiva + Folio Mercantil
Constitutive Documents	All required: Acta Constitutiva + Estatutos Sociales
Tax Registration	Constancia de Situación Fiscal
Operating Permit	Licencia de Funcionamiento
Ownership Records	All required: Acta Constitutiva + Libro de Registro de Acciones
Governance Records	All required: Acta Constitutiva + Acta de Asamblea
Signing Authority	All required: Acta de Asamblea + Poder Notarial
Address	Any one of: Contrato de Arrendamiento · Comprobante de Domicilio · Estado de Cuenta Bancario
Good Standing	Any one of: Folio Mercantil · Constancia de Situación Fiscal

Documents to collect

The physical documents you’ll collect from your customer, with the evidence area each one proves. One document can prove multiple areas — for example, Brazil’s Cartão CNPJ covers both tax and business-registration proof, so it appears once with both areas listed.

Document	Proves
Acta Constitutiva	Legal Registration, Constitutive Documents, Ownership Records, Governance Records
Folio Mercantil	Legal Registration, Good Standing
Estatutos Sociales	Constitutive Documents
Constancia de Situación Fiscal (RFC)	Tax Registration, Good Standing
Licencia de Funcionamiento (municipal)	Operating Permit
Libro de Registro de Acciones	Ownership Records
Acta de Asamblea	Governance Records, Signing Authority
Poder Notarial	Signing Authority
Contrato de Arrendamiento	Address
Comprobante de Domicilio (≤90 días)	Address
Estado de Cuenta Bancario (≤90 días)	Address
Sector-Specific License	CNBV, CONSAR, CNSF, COFEPRIS

Collection notes

Address: Accepted evidence: lease agreement (no time limit) or utility bill or bank statement dated within 90 days. Either document satisfies both registered-address and operating-address verification.
Good Standing: No standalone good-standing certificate is issued; a recently dated copy of the listed document evidences current standing. Mexico has no standardised national Certificate of Good Standing; a recently dated certified Folio Mercantil extract from the state-level Registro Público de Comercio (collected under business_registration) reflects current registration status, and a current Constancia de Situación Fiscal from SAT evidences tax good standing.
