Company search by registration number (MB)

What is a matični broj?

The matični broj (MB) is the unique eight-digit registration number the Serbian Statistical Office assigns to every business when it is founded. It stays with the company for its whole life and never changes — it is used in the APR business register, in contracts and in official documents.

Search by MB to see available company status, activity, financial data, and changes observed between archived snapshots. An MB can start with a zero — enter all eight digits.

Where to find a company's registration number

The registration number appears on contracts, letterheads, invoices and the registration decision. If you only know the name, search for the company on pravno.rs by name: the MB is listed in the profile's basic information, with a copy button.

Registration number (MB) vs. PIB

The registration number identifies a company in registers and statistics; the PIB identifies it in the tax system. Every company has both, and companies print them on their business documents. An MB has eight digits, a PIB nine.

A sole proprietor's MB and JMBG

A sole proprietorship has its own eight-digit registration number, which is not the owner's thirteen-digit personal ID (JMBG). pravno.rs does not show personal ID numbers.

Frequently asked questions

Does the registration number ever change?

No. The MB stays the same when a company changes its name, address or owners, so it's a more reliable way than the name to confirm you're looking at the same company.

Can I find a closed company by its registration number?

Yes. Struck-off and inactive companies stay available, with their status from the APR register.

Why doesn't the search find a registration number?

Enter all eight digits, including a leading zero. Sole proprietors are only covered if they are registered in the e-Invoice system (SEF).

Is the search free?

Yes. Search and company profiles are free and need no registration.
