What is a SIRET generator for Nord used for?

Developers and QA teams often need realistic test data that resembles real French companies. A department-specific SIRET generator allows you to:

  • Test forms that validate SIRET format and postal address
  • Populate demo databases with fictional companies geolocated in Nord
  • Simulate business scenarios involving companies from the Hauts-de-France region
  • Train teams without using real data from existing companies

All generated SIRETs are algorithmically valid (verified Luhn key) but do not correspond to any company registered in the INSEE SIRENE registry.

FAQ

How to generate a fake SIRET number for Nord?

Use our generator above to get fake SIRET numbers with addresses located in the Nord department (code 59). SIRETs are generated according to the Luhn standard, accompanied by the corresponding SIREN, company name and a real postal address in the Hauts-de-France region.

Is it legal to use a fake SIRET number?

Yes, using fake SIRET numbers is perfectly legal in a testing, software development, training or demonstration context. It is important to never use these numbers for real commercial transactions or administrative declarations, which would constitute fraud.

What is the structure of a SIRET number?

A SIRET number consists of 14 digits: the first 9 form the SIREN number (unique identifier of the company), and the last 5 constitute the NIC (Internal Classification Number), which identifies the establishment within the company. The last digit of the SIRET is a control key calculated using the Luhn algorithm.

Can I use these fake SIRETs in an application?

Yes, the generated SIRET numbers are algorithmically valid (correct Luhn key) and can be used to test forms, APIs or databases that validate the SIRET format. However, they do not correspond to any real company in the INSEE SIRENE register.

What is the difference between SIREN and SIRET?

The SIREN (9 digits) identifies a company as a legal entity. The SIRET (14 digits) identifies a particular establishment of that company — a physical address. The same company can have multiple SIRETs (head office + branches), but only one SIREN.
