In accordance with Mexican legislation, companies in Mexico must report all customer and vendor transactions in the Declaración Informativa de Operaciones con Terceros (DIOT), a tax declaration that is submitted to the Servicios de Administración Tributaria (SAT). The following tax registration IDs are included in the DIOT: the Registro Federal del Contribuyentes (RFC) number, Clave Única de Registro de Población (CURP) number, and state inscription number.

The RFC number and state inscription number are assigned to both individuals and corporations, but CURP numbers are assigned only to individuals. The formats of the tax registration numbers are shown in the table below.
