NIF Algeria 2026: obtaining your tax identification number

The NIF (tax identification number) is the unique tax identifier assigned by the DGI (tax directorate) to every taxpayer, whether an individual or a legal entity. It serves to record and monitor all of the tax obligations of a business or a professional.

The NIF is distinct from the NIS (statistics identification number, issued by the ONS) and from the commercial register number (CNRC). It appears on the tax card (carte fiscale), on tax returns (G50), on invoices and on the company's official documents.

The Algerian NIF is a numeric sequence assigned by the DGI. For an individual, it generally has 15 digits. For a legal entity, the number is longer and often has 20 digits.

The extended format for legal entities is required in particular for customs and import procedures, where a complete and up-to-date NIF is demanded to clear goods through customs. An individual and a company therefore do not necessarily have a number of the same length.

The NIF appears on the tax card issued by the DGI, as well as on tax returns (G50), invoices and the company's official documents. Because its inclusion on invoices is mandatory, it must be entered there without error.

For an auto-entrepreneur, the NIF is generated automatically upon online registration, with no separate step at the DGI. Registration for auto-entrepreneur status is carried out exclusively online on the portal of the National Auto-Entrepreneur Agency (ANAE), at anae.dz.

During registration, a tax identification number (NIF) is assigned automatically to the applicant and becomes accessible from the platform. An auto-entrepreneur who did not yet have a NIF thus receives one as part of the application for the auto-entrepreneur card.

This NIF allows the auto-entrepreneur to issue compliant invoices, open a business bank account and declare the single flat-rate tax (IFU). According to the ANAE, the auto-entrepreneur does not need a separate NIS to operate or to open a bank account: the NIF alone is sufficient for these steps. UpGrowth can guide you step by step through ANAE registration and the associated tax procedures.

For a business, the NIF is obtained after registration in the commercial register (CNRC): the RC extract is part of the tax registration file. The usual sequence is therefore: company name (negative certificate), then articles of association and RC at the CNRC, then the NIF at the DGI, then the NIS and CASNOS/CNAS affiliation.

The NIF (tax, DGI) and the NIS (statistical, ONS) are two distinct but complementary identifiers, both required for the company to operate legally.

To verify a NIF online, use the 'Authenticate your NIF' service on the official portal of the DGI. You enter the number to be checked and the service confirms its validity along with the linked identity, i.e. the company name or the taxpayer's name. Verification is free and immediate.

The procedure has four stages. First, open the DGI's online NIF portal at its current address, nifenligne.mf.gov.dz, which came into effect in 2026 to replace the former address nifenligne.mfdgi.gov.dz. Next, open the NIF authentication service. Enter the tax identification number to be verified. Finally, confirm to display the status of the number and the corresponding identity.

This verification is used mainly to check the tax existence of a customer, a supplier or a partner before signing a contract, issuing an invoice or processing a payment. A valid NIF confirms that the entity is indeed registered with the DGI.

This authentication must be distinguished from searching for your own NIF. The DGI's online service authenticates an existing number; it does not disclose a number to a third party. If you have forgotten yours, it appears on your tax card, on your G50 returns and on your invoices. If lost, contact the tax office (CDI) to which you report.
