In accordance with Mexican legislation, companies must report all customer 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 must be 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 format of the tax registration number depends on the entity type, as shown in the table.

Tax registration ID	Entity type	Format
RFC	Corporations	12 characters in length. The first three characters represent the business name. The next six characters represent the date of the registration (YYMMDD). The last three characters are assigned by the government at random.
RFC	Individuals	13 characters in length. The first four characters represent the name of the person. The next six characters represent the person’s date of birth (YYMMDD). The last three characters are assigned randomly.
CURP	Individuals	18 characters in length. The first four characters represent the name of the person, the next six characters represent the person’s date of birth (YYMMDD), the next character represents the gender of the individual (M: female or H: male), the next two characters represent the state where the person resides, and the last five characters are assigned randomly.

Use the Customers form to specify the CURP and RFC for a customer. When you create a sales order, the CURP and RFC numbers of the customer are printed in the following documents and reports:

• All documents submitted to the customer.

• Declaración Informativa de Operaciones con Terceros (DIOT).

• Confirm report – Generated when you confirm and print a sales order.

• Packing slip report – Generated when you confirm the packing slip.
