6 Best B2B Data Providers in Serbia in 2026

The APR (Agencija za privredne registre, Business Registers Agency) is Serbia's official company registry, accessible at apr.gov.rs. All Serbian legal entities are registered with an MB (matični broj, company registration number) and PIB (poreski identifikacijski broj, tax identification number). The APR is the authoritative source of Serbian company data including financials, ownership, and registration details. Financial statements submitted to APR are publicly accessible for all registered companies.

Serbia has its own data protection law — the Law on Personal Data Protection (Zakon o zaštiti podataka o ličnosti, ZZPL), modelled closely on the GDPR. It is enforced by the Commissioner for Information of Public Importance and Personal Data Protection (Poverenik za informacije od javnog značaja i zaštitu podataka o ličnosti). While Serbia is not an EU member, it is an EU accession candidate and has aligned its data protection framework with GDPR principles.

Serbia has approximately 350,000–400,000 registered entities in the APR, of which roughly 200,000–250,000 are active companies. Belgrade is the dominant economic centre, accounting for the majority of company registrations. Novi Sad, Niš, and Kragujevac are other significant business hubs. Serbia has a growing IT sector and a strong manufacturing and agri-food base.

Key B2B sectors in Serbia include information technology and software (Serbia is one of the largest IT exporters in the Western Balkans), manufacturing (automotive supply, metal processing, food processing), agriculture and agri-food, energy, construction, and retail trade. KD (klasifikacija djelatnosti) codes, aligned with NACE, are used for industry classification in Serbian company data.
