What is an Algerian NIF?

The NIF (Numero d'Identification Fiscale) is the 15-digit fiscal identifier issued by the DGI Algeria to taxpayers. It is required on invoices, tax declarations and public-procurement submissions.

How many digits is an Algerian NIF?

Exactly 15 digits. This validator rejects any value that is not 15 numeric digits after spaces and hyphens are removed.

Does the NIF have a check digit?

No publicly documented weighted check-digit algorithm exists for the Algerian NIF. This tool validates the official 15-digit structure rather than a checksum.

How is the NIF structured?

It is commonly split into a 13-digit base identifier derived from the trade register or national identity, followed by a 2-digit activity or branch suffix. The tool shows both segments.

Is my NIF sent anywhere?

No. The check runs entirely in your browser, so the NIF never leaves your device and nothing is logged or transmitted.

Algeria NIF Validator

The Algerian NIF (Numero d’Identification Fiscale) is the 15-digit fiscal identifier the DGI Algeria issues to companies and individuals. It is mandatory on invoices, VAT declarations and public-procurement documents, and an incorrectly formatted NIF will be rejected by Algerian tax systems. This free validator confirms the structure entirely in your browser.

How it works

The NIF is a fixed 15-digit numeric code. This validator applies the official structural rules:

Strip spaces and hyphens so you have 15 continuous digits.
Confirm the value is exactly 15 digits and contains nothing but digits.
Reject an all-zero value.
Split the code into a 13-digit base identifier and a 2-digit activity / branch suffix.

Because Algeria publishes no weighted check-digit formula for the NIF, the tool validates structure rather than computing a checksum.

Example

A NIF such as 000216001234567 is reported as valid, with base identifier 0002160012345 and activity / branch suffix 67. A 14-digit value is rejected as the wrong length.

A valid result confirms the number is well-formed, not that the taxpayer is actually registered. To confirm registration, verify with the DGI. All processing stays on your device.
