The text of the template

The wording stays in French, the language this request is filed in at the counter. The text below is the text of the Word file, reproduced so you can read, copy or adapt it without downloading anything. The items in blue are the fields to replace with your own details.

FICHE DE DEMANDE DE DÉNOMINATION SOCIALE

Declaration to complete and attach to the company name application form of the Centre National du Registre du Commerce

This sheet accompanies the CNRC company name application form, it does not replace it. The negative certificate is issued by the CNRC on the basis of its own form, filed at the counter or on the sidjilcom.cnrc.dz portal. The sheet below stays in French, the language it is filed in.

How to use this sheet

  • Replace every field between square brackets with your own details. They are highlighted in the document.
  • Propose several names, ranked by order of preference. The CNRC keeps the first available one, which spares you a second trip if the first is refused.
  • Write each proposal in Latin script and in Arabic script. Both transcriptions are recorded.
  • Check the trademark with INAPI before filing. A registered trademark prevails over a plain trade name entered in the trade register.
  • Keep the proposed name consistent with the declared activity. An obvious mismatch with the activity code can be grounds for refusal.
  • Attach the applicant's identity document, the completed CNRC form and the receipt for the fees, plus the power of attorney if a representative files on your behalf.

Worth knowing before you file

  • The negative certificate states that no already registered company is using the requested name. It is a document of availability, not a title of ownership under trademark law.
  • The period of validity of the reservation is written on the certificate you are handed. Note it down, and set your notary appointment inside that window.
  • Copy the name exactly as it appears on the certificate, into the articles of association, into the minutes and onto the registration form. One accent or one space of difference between two documents of the same file is enough to send it back from the counter.
  • A refusal can be based on similarity with an existing name, on the use of a reserved term, or on an inconsistency with the declared activity.
  • The documents required and the fees due are published by the CNRC and can change. Check them on sidjilcom.cnrc.dz before you travel.
  • If you would rather have a drafted letter than a field by field sheet, our negative certificate request letter carries the same request as a letter addressed to the director of the branch.

UpGrowth Connect handles it for you

Have UpGrowth draft and file it

File assembly, filing with the CNRC and follow-up until issuance

The online service is SIDJILCOM

The name application and the issuance of the negative certificate run on SIDJILCOM, the portal of the Centre National du Registre du Commerce, at https://sidjilcom.cnrc.dz. That is the official service, that is where the certificate comes from, and no other site issues it.

The negative certificate states that no already registered business trades under the name you are applying for. It is the first document of an incorporation file: without it a notary cannot draft the articles of association, since the company name appears in them.

Filing at the counter of the CNRC branch covering the intended registered office is still possible. The choice does not change the document issued, it changes the journey.

Before you log in, check the name is free

  • Use the portal search to see whether the name is already taken. It is free and it saves a wasted filing.
  • Check prior rights with INAPI. A registered trademark prevails over a mere trade name entered in the commercial register, and a conflict discovered after registration costs far more than a prior search.
  • Rule out reserved terms or wording likely to mislead about the nature of the activity, in particular anything suggesting a regulated activity you do not carry out.
  • Keep the name consistent with the declared activity code. An obvious mismatch between the two can block the file.
  • Prepare several proposals rather than one, ranked by preference. The CNRC keeps the first available one, which avoids a second filing if one is refused.

The online application, field by field

  • Create your account on the portal. Registration asks for an email address and a phone number.
  • Open a new application, then the name reservation section.
  • Enter the applicant's identity: identity document, address, phone.
  • Enter your proposed names, ranked by preference. The system checks availability against the CNRC database.
  • State the intended legal form, SARL, EURL, SPA or another.
  • Describe the main activity precisely, in line with the CNRC nomenclatures.
  • Attach a copy of the identity document of the founder or founders, and the power of attorney if an agent acts for you.
  • Pay the fees online. The scale is set by the CNRC and displayed at the moment of payment.
  • Submit the application, then follow its status from your account.

Documents to prepare

  • A valid, legible identity document for the founder or founders.
  • A power of attorney if a third party files on your behalf.
  • The receipt for the fees, worth keeping.
  • The cover letter, if an agent files for you or if you want a dated written trace of your request.

What the name reservation costs

On the files handled by UpGrowth in 2026, the trade name costs 1,000 DZD. That is what we observe on our own files, not a scale we set.

Fees are set by the CNRC and can change. Check the amount displayed on the portal when you pay rather than trusting a figure read elsewhere, including here.

Processing time and validity

Processing time depends on the CNRC and on the branch concerned. We do not announce it on their behalf. The only lever that belongs to you is filing a complete file the first time.

The validity period of the reservation is stated on the certificate handed to you. We publish no figure here: the text that sets it was not found in the official sources we consulted, and an approximation on this point is paid for with a second filing.

Note the date on your certificate and schedule the notary appointment inside that window.

Frequent grounds for refusal

  • Name already taken by another company.
  • Name too close to an existing one in the same sector, including where the closeness is only phonetic.
  • Name matching a trademark filed with INAPI.
  • Use of protected words without authorization.
  • Declared activity too vague or not in line with the CNRC nomenclatures.
  • Expired or unreadable identity document.
  • Payment not validated by the bank.

The cover letter, full text

The portal processes the request on the basis of its own form. A cover letter is still useful in three cases: when an agent files on your behalf, when you want to propose several names in a defined order, and when you want a dated written trace of your request.

We publish that letter in full, readable without downloading anything, with the fields to complete highlighted and the matching Word file. It sits on our page devoted to the negative certificate request letter.

Once you have the certificate

  • Hand the certificate to the notary for the articles of association, with the name copied exactly, down to the accent and the space.
  • Reserve the matching domain name while you are at it.
  • Consider filing the name as a trademark with INAPI if it carries your commercial positioning. The CNRC certificate protects against company namesakes, it is not a trademark title.
  • Carry on with the incorporation, BOAL publication, capital deposit and registration, inside the validity window stated on the certificate.
