How the Numéro d'Identification Nationale (NIN) format works
- Format
- 18 digits encoding sex/birth-record type, birthplace, a municipality code, birth year and a registration/serial number
- Example
- 109880554003450000
Things to watch for
- Format-only check — does not confirm the NIN was actually issued or belongs to a real person
- The digits encode sex, birth-record type, birthplace, municipality and a registration number, but this checker validates the 18-digit shape only — it does not decode those embedded fields
- Runs entirely in your browser — the number you enter is never transmitted or stored
^[0-9]{18}$Algeria’s Numéro d’Identification Nationale (NIN) is the 18-digit number the Ministère de l’Intérieur et des Collectivités Locales assigns to residents, for example 109880554003450000. It’s one of the longer national ID numbers in this list, and for a reason: rather than a short serial, it’s built to encode a sex and birth-record-type indicator, a birthplace code, a municipality code, the holder’s birth year, and a registration or serial number, all concatenated into the 18-digit string.
Because Algeria’s civil-status authority hasn’t published the exact character-by-character segment boundaries for public reference, this checker treats the NIN as one 18-digit block rather than attempting to split it into fields it can’t reliably verify.
What this checker verifies
This tool confirms the input is exactly 18 digits, catching a wrong length or a non-numeric character. It does not decode the sex, birth-record-type, birthplace, municipality or registration segments packed inside those digits.
What a pass doesn’t confirm
A pass doesn’t mean the Ministère de l’Intérieur actually issued that NIN or that it belongs to a real person — only that the digit count matches.
Scope: format-only validation, running entirely in your browser — nothing you type is transmitted or stored.

Numéro d'Identification Nationale (NIN) FAQ
What does an 18-digit Algerian NIN encode?
It's built from a sex and birth-record-type indicator, a birthplace code, a municipality code, the birth year, and a registration or serial number — all packed into the 18 digits, though this checker doesn't decode where each segment starts and ends.
Why 18 digits, longer than most other national IDs?
Algeria's Numéro d'Identification Nationale packs in more location and record-type detail than many countries' ID numbers — birthplace and municipality codes alongside the birth year and a registration number — which is why it runs to 18 digits rather than 11 or 12.
Does a correctly formatted NIN confirm it was actually issued?
No. It only confirms the input is 18 digits — it can't confirm Algeria's Ministère de l'Intérieur actually issued that specific number to a real person, and it doesn't decode the embedded fields.
