Anatomy & Structure of Argentine DNI (RENAPER)
The National Identity Document in Argentina is structured as follows:
| Position | Field | Length | Meaning & Rule | Example |
|---|---|---|---|---|
| 1 to 7/8 | Civil Identity Serial | 7 or 8 digits | Unique number assigned by RENAPER (7 digits for historical records, 8 digits for modern series) | 12.345.678 |
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. Strip dots and spaces (valid masked formats: XX.XXX.XXX or X.XXX.XXX).
- 2. Verify total length is strictly 7 or 8 numerical digits.
- 3. Ensure number falls in the recognized demographic range (1,000,000 to 99,999,999).
- 4. Reject artificial trivial sequences (e.g. 00000000, 11111111).
