Argentine DNI test number generator
Generate random Argentine DNI (national ID) numbers in realistic ranges by age, with or without dots and with their matching CUIL. For testing and QA.
Generated numbers are fictitious data for software testing: they have a valid format and check digit, but do not belong to real people, accounts or cards. Do not use them for real transactions.
| DNI | CUIL | Gender | Approx. birth year |
|---|
How it works
Choose how many, the approximate age range and the format (12345678 or 12.345.678) and get random DNI numbers. Argentine DNIs are issued sequentially, so the number roughly indicates the birth year: the tool uses that relationship to generate numbers consistent with age.
Optionally, each DNI comes with a valid CUIL for the chosen gender. You can copy the list or download it as CSV.
Frequently asked questions
How many digits does an Argentine DNI have?
Currently 8. People born before the 1970s may have 7, and new numbers for foreign residents start at 90 million.
Does a DNI have a check digit?
No. That is why the CUIL, which has one, is used for validation.
