Romania’s tax landscape is moving faster than a Bucharest commute at rush hour. In the rapidly evolving digital landscape of Eastern Europe, a precise understanding of Romania’s Tax Identification Numbers — specifically the CIF, CNP, and the VAT Number — is essential for corporate compliance, KYB (Know Your Business) checks, and navigating the phased mandatory RO e-Factura expansion in 2026.
Between the ANAF’s strict oversight and the high stakes of “fiscal inactivity,” getting a single digit wrong isn’t just a typo—it’s a significant financial liability.
