NIS in Algeria: the statistical identification number, how it differs from the NIF and how to obtain it

The NIS is the identifier assigned by the Office national des statistiques (ONS) to economic and social agents. It serves to enter each entity in the répertoire national des agents économiques et sociaux, the national register of economic and social agents, the database that allows the national statistical apparatus to know who exists, where, and in which activity.

Its logic is statistical before it is administrative, and that is what throws founders off. The NIS opens no right and creates no reporting obligation of its own. It identifies. But because it identifies in a unique and stable way, it has established itself as a supporting document in a great many files that have nothing statistical about them.

The number has fifteen digits for the main establishment. Secondary establishments receive the fifteen digit number of the parent entity, completed by three sequential digits. This construction makes it possible to attach an establishment to its parent company immediately, simply by reading the number, which explains why administrations insist on it for multi site companies.

The document issued is called the identification certificate (certificat d'identification). The ONS states that it is issued free of charge, which clearly sets this formality apart from most other company formation steps.

The last row of the table carries the most useful information for organising your steps. The NIS file requires a copy of the tax card or of the certificate of existence: in other words, you go through the tax administration before the ONS, and not the reverse. A founder who turns up at the ONS before obtaining the NIF leaves with the file still in hand.

Historically, the ONS came before the DGI on this ground. The NIS rests on texts from the 1990s, while the tax identification number is more recent. The tax administration thus equipped itself with its own identifier, which explains why two numbers coexist where one would suffice in theory. Our page devoted to the NIF details that second identifier (/nif-algerie), and our tool lets you check one (/verifier-nif-algerie).

The ONS attaches the scheme to a set of texts, the most structuring of which is legislative decree no. 94-01 of 15 January 1994 on the statistical system. That text establishes the principle of a statistical identification of natural and legal persons resident on national territory.

Executive decree no. 97-396 of 28 October 1997 then sets out the scheme in detail and creates the national register of economic and social agents. That register is what the NIS feeds: each number assigned corresponds to an entry in the register.

The ONS further cites ordinance no. 95-27 of 30 December 1995, ordinance no. 96-31 of 30 December 1996 and the finance law for 2002 among the texts founding the obligation. Those finance texts are the ones that progressively made the number compulsory in administrative files, and therefore turned a statistical identifier into a required document.

It is worth noting what this framework does not provide for. None of the texts consulted sets a regulatory deadline for issuing the identification certificate, and the ONS publishes none. We will therefore not repeat the durations that circulate, for want of an official source.

The scope is therefore broad and goes beyond the commercial field alone. A craftsperson registered in the registre de l'artisanat et des métiers, the register of crafts and trades, falls into the second category and provides their artisan card in place of the trade register extract.

For a company with several establishments, each secondary establishment receives its own three digit suffix attached to the number of the parent company. This variant is not optional once the secondary establishment is registered in its own right.

Two points deserve attention. The first is the alternative between the tax card and the certificate of existence: a company whose tax card has not yet been printed can proceed with the certificate of existence issued by the tax services, which avoids waiting before starting the NIS formality.

The second concerns natural persons, who must attach a birth certificate extract N° 12. The ONS names it that way, and an ordinary extract does not replace it: this is a classic reason for an incomplete file.

Filing takes place with the regional directorate competent for the place of establishment, and not systematically at the national headquarters of the ONS. This is a source of error for companies in wilayas far from Algiers, which sometimes travel for nothing.

The fact that issuance is free deserves emphasis in a formation process where almost every step has a price. An intermediary who invoices the NIS is invoicing a support service, not a tax: the distinction must be clear on the quotation.

The NIS appears in files wherever the entity must be identified in a stable and unique way: opening and running professional bank accounts, administrative files, dealings with public bodies, statistical surveys and returns.

The question founders ask most often is the one about redundancy. If the NIF already identifies the company, why produce the NIS as well? The answer lies in where the two numbers come from. They do not originate in the same database and they are not managed by the same administration: the NIF comes from the tax sphere, the NIS from the national statistical register. A bank that collects both is not being overzealous, it is satisfying two distinct reference systems.

Cross-checking the two numbers also makes it possible to detect inconsistencies. An entity declared under one corporate name at the ONS and another at the DGI signals an update problem in one of the two files, often following a change that was never passed on.

This is the moment to recall that these numbers rest on data declared elsewhere. A change of name or of registered office is passed on first to the trade register, within the month following the change since law 26-12 (/modification-registre-commerce-algerie), before it can be reflected in the other reference systems.

In a formation file, the NIS comes late and nobody thinks about it. The founder works through the negative certificate, the articles of association, registration in the trade register, the NIF, the tax card, social affiliation and the opening of the bank account. The NIS slots in between the tax card and the bank, and it is often the banker who reminds the founder that it exists.

The sequence is simple, however, once you know it: tax services first for the tax card or the certificate of existence, then the ONS with that document. The reverse does not work.

UpGrowth Connect treats the NIS as a step in the formation process, on the same footing as registration or the NIF, and not as a separate errand the client would discover after the fact.
