## Technical Overview & Governing Rules
In Romania, the Value Added Tax (VAT) identification number begins with the country prefix 'RO', followed by the national format: 2 to 10 digits (Cod de identificare fiscală).

The number format is governed by national tax authorities and verified via strict syntax and structural pattern matching.

For 2026 tax calculations, the standard VAT rate in Romania is 21%, with applicable reduced rates of 11%, 9%.

Romania raised its standard VAT rate from 19% to 21% on 1 August 2025 under Law 141/2025; the reduced rate became 11%, with 9% retained for qualifying residential property until 1 August 2026.
