What is a Mauritanian NIF?

The NIF (numéro d’identification fiscale; الرقم الضريبي) is the number Mauritania’s Direction Générale des Impôts assigns to a taxpayer after it files a declaration of existence. The NIFs we found in official notices have 8 digits — for example 11400067 — and an invoice without the supplier’s NIF loses the buyer its expense and VAT deductions.

Mauritanian NIF format

Eight digits, as printed in official notices.

11400067 Eight digits

Example: 11400067 (GLP SARL, Nouakchott, in a Ministry of Health provisional contract-award notice of 23 January 2026).

  • No published format: The DGI publishes no format or check digit; the 8-digit shape is taken from official notices.
  • Input: Spaces and hyphens are removed automatically. No MR prefix.
  • Not a NIF: The NNI, the RC number and the e-filing number (NTD) are different numbers.
  • Register lookup: The register often doesn’t respond; the checker then reports that the registry was temporarily unavailable.

How to check a Mauritanian NIF

  1. 1 Find the NIF on the supplier’s invoice — the tax code requires it there.
  2. 2 Enter the 8 digits above. The checker confirms the format and tries the register.
  3. 3 If the register doesn’t answer, ask the supplier for its NIF registration document before relying on the number.

Frequently Asked Questions

How many digits does a Mauritanian NIF have?

The NIFs we found printed in official notices have 8 digits — for example 11400067 for GLP SARL in a Ministry of Health procurement notice. The Direction Générale des Impôts (DGI) does not publish a format specification or a check digit.

Can I check a Mauritanian NIF online? (Vérification du NIF)

The DGI publishes a NIF verification that returns the registered name, trade name and status. The checker on this page confirms the 8-digit format and looks the number up when the register responds; if the result says the registry was temporarily unavailable, the register did not answer.

Why must the supplier’s NIF be on the invoice?

Under the tax code, a buyer cannot deduct the expense or the input VAT on an invoice that lacks the supplier’s NIF. A B2B invoice must also carry the buyer’s NIF.

Who must get a NIF?

Anyone liable to corporate tax, business income tax or VAT, or acting as a withholding agent, whether resident or not. They file a déclaration d’existence within 20 days, and the DGI then assigns the NIF. Registration is free.

Is there a separate VAT number in Mauritania?

No separate VAT number was found. VAT status is shown by a DGI certificate (attestation d’assujettissement à la TVA), and invoices carry the NIF.

Is the NIF the same as the NNI or the RC number?

No. The NNI is an individual’s national identification number and the RC is the commercial-register number; the DGI asks for each separately from the NIF.
