Document format and locale facts for Serbia

Use these defaults as a practical starting point for presentation. ISO/CLDR formatting facts are not legal or tax advice, and reviewed jurisdiction guidance is identified separately.

Why these defaults?

The country code comes from ISO 3166. Unicode CLDR supplies presentation-oriented locale, currency, paper, date, language, calendar, numbering, and direction metadata. Defaults reduce setup time; they do not decide what a valid document must contain.

Recorded official or regional-official language tags: sr, sr-Latn, hu, ro, hr, sk, uk.

Serbia's SEF API, EN 16931-1 adaptation and selected invoice/VAT-document context are reviewed. Full field schema, taxpayer identity validation, scope/mandate applicability, API authentication, structured-document generation, submission/acceptance, VAT recording and transaction-specific treatment remain separately researched or unimplemented scopes.

  • Guidance: Serbia's Ministry of Finance Electronic Invoice System (SEF) publishes an API specification and instructions for connecting through an API. It publishes an adapted implementation of EN 16931-1 for domestic electronic invoices, while the current API documentation shows invoice document number, currency, VAT amount and related invoice/credit-note/debit-note data. SEF's public user list identifies users through their tax identification number (PIB). This local preview does not validate PIB, create the Serbian SEF/EN 16931 structured document, authenticate to SEF, use an API key, submit, receive/accept/reject, record VAT, or determine mandate applicability and transaction-specific VAT treatment.Evidence RS_MFIN_SEF_DOCUMENTS, RS_MFIN_SEF_API, RS_MFIN_SEF_CURRENT_API_DOCS, RS_MFIN_SEF_PIB_USERS · reviewed 2026-07-18 · review by 2027-01-18 · automation advisory only
