Key Considerations for Mexican National ID

When processing Mexican National ID cards, ensure the following to avoid common validation errors:

  • Both paternal and maternal family names are required. Enter them exactly as shown on the ID, using uppercase letters.
  • Given names: Include all given names in the correct order and with proper capitalization.
  • Date of birth: Use the exact format YYYY-MM-DD as printed on the document.
  • ID number: Enter the complete and correct ID number as it appears on the card.
Document Number Verification

The Mexican National ID may be issued as either:

  • INE (Instituto Nacional Electoral) — the current version
  • IFE (Instituto Federal Electoral) — the previous version

Both INE and IFE cards are valid for verification. Ensure the document number is entered exactly as it appears on the card, regardless of version.
