Company search by tax ID (PIB)
Enter the nine-digit tax identification number (PIB) to find a company with an available tax ID.
What is a PIB?
The PIB (poreski identifikacioni broj) is the unique nine-digit tax identification number the Serbian Tax Administration assigns to every business at registration. It identifies the business in the tax system: on invoices, in tax filings and in the e-Invoice (e-Faktura) system.
The PIB is public information. Searching by PIB lets you check whether a company is active, what it does and how it performs financially — useful before signing a contract or paying in advance.

Where to find a company's PIB
The PIB appears on invoices, fiscal receipts, contracts and the company's letterhead. If you only know the name, search for the company on pravno.rs by name: the PIB is listed in the profile's basic information, with a copy button.
PIB vs. registration number (MB)
The registration number (matični broj) identifies a company in registers and statistics; the PIB identifies it in the tax system. Every company has both, both are permanent, and companies print them on their business documents. A PIB has nine digits, an MB eight.
PIB and VAT
Serbian VAT payers have no separate VAT number: the PIB is used in the VAT system too. pravno.rs checks whether a company is VAT-registered in the Tax Administration's records and shows it on the company profile, alongside bank accounts and enforced-collection data.
What a valid PIB looks like
A PIB has exactly nine digits, with no letters or spaces. The last digit is a check digit computed from the first eight (ISO 7064, MOD 11,10), so a mistyped PIB usually matches no company at all.
Frequently asked questions
Is a PIB public information?
Yes. A company's PIB is printed on its invoices and listed in public registers, so anyone can check it.
Can I find a sole proprietor by PIB?
Partly. APR publishes no open data on sole proprietors, so pravno.rs only covers those registered in the e-Invoice system (SEF).
Why doesn't the search find a PIB?
Check that you entered all nine digits. A PIB isn't available for every company: it is shown when public sources link it to a registration number. In that case, search by name or registration number.
Is the search free?
Yes. Search and company profiles are free and need no registration.
