Naming Conventions for the Auxiliar de Cuentas XML File

You must manually rename the XML file that the system generates to meet the naming conventions requirements that the fiscal authority sets, before you submit it. For the Auxiliary XML file, the name contains:

  • The 12 or 13 characters of the RFC number

  • The year (four digits) and the month (two digits)

  • XML type identification: Use XC for the Auxiliary Ledger by Account (Auxiliar de Cuentas) file

  • Extension XML (.xml)

For example, if the RFC number of your company is 888888888888 and you are submitting an Auxiliary Ledger by Accounts XML file for July of 2015, the name of the file should be 888888888888201507XC.XML.

Ensure that both the XML file generated and the compressed ZIP file that you submit, comply with the naming convention requirements.
