CURP status codes

When verifying a CURP (Clave Única de Registro de Población), RENAPO may return different status codes depending on the individual’s registration history. These statuses indicate whether the CURP is valid and active, or has been deactivated due to various reasons such as administrative changes, death, or judicial orders.

Active statuses (AN, AH, RCC, RCN) represent valid CURPs that can be used for identity verification.
Inactive statuses are considered invalid and must be rejected during verification.

CURP status	Description	Registration status	Comments
AN	Normal registration	Active	–
AH	Registration with homonymy (duplicate name handling).	Active	–
RCC	Registration updated with changes that affect the CURP key itself (e.g., identity or registry data changes).	Active	CURPs that had a modification impacting the key.
RCN	Registration updated with changes that do not affect the CURP key.	Active	–
BAP	Cancelled due to apocryphal/invalid supporting document.	Inactive	CURPs generated with fraudulent or invalid documentation.
BSU	Cancelled for non-use.	Inactive	CURPs with no activity since issuance (not revised, printed, or used). To reactivate, a request must be made through the CURP module.
BD	Cancelled due to death	Inactive	–
BDM	Cancelled administratively.	Inactive	CURPs deactivated at the request of the issuing authority.
