Official Argentine DNI Validation Rules

RENAPER validates civil ID numbers through structural integrity requirements:

length >= 7 && length <= 8 && /^[0-9]+$/.test(digits) && !/^(\d)\1+$/.test(digits)
  1. 1. Strip dots and spaces (valid masked formats: XX.XXX.XXX or X.XXX.XXX).
  2. 2. Verify total length is strictly 7 or 8 numerical digits.
  3. 3. Ensure number falls in the recognized demographic range (1,000,000 to 99,999,999).
  4. 4. Reject artificial trivial sequences (e.g. 00000000, 11111111).
