CURP and RFC newcomer registration in Mexico
Document Checklist
Documento migratorio vigente
Documento migratorio vigente
Form: Original — Tarjeta de Residente Temporal, Tarjeta de Residente Permanente, Tarjeta de Visitante con permiso para realizar actividades remuneradas, or the INM/COMAR application receipt where the underlying procedure is still open.
Required for: RFC inscripción at SAT; the documento migratorio vigente also serves as the identificación oficial for foreigners.
Tourist conditions of stay do not satisfy the documento migratorio vigente requirement — RFC inscripción cannot proceed.

CURP
Form: 18-character alphanumeric code, printed on the Constancia CURP. Standard CURP for INM-card holders; Constancia Temporal CURP for foreigners with an in-progress INM or COMAR application.
How to obtain: Standard CURP is generated at the time the INM card is issued. Constancia Temporal CURP is requested at the same INM module or COMAR module where the migratory procedure is being processed.
Verified by SAT directly from the RENAPO registry at RFC inscripción — no separate paper presentation required.
