Dominican RNC / Tax ID Lookup 🇩🇴 — Full DGII Registry

Instantly verify any Dominican Republic taxpayer — individuals and businesses — against the official DGII (Dirección General de Impuestos Internos) registry.

Current database: 771,000+ taxpayers (updated April 2026). Covers all statuses: active, suspended, deregistered, temporarily ceased, annulled, and rejected.

Why this matters: In the Dominican Republic, every fiscal invoice (comprobante fiscal) requires a valid RNC. Invalid or suspended RNCs mean rejected invoices, DGII penalties, and compliance risk.

Frequently asked questions

What is an RNC? RNC (Registro Nacional de Contribuyentes) is the tax identification number assigned by DGII to every taxpayer in the Dominican Republic. Businesses use a 9-digit RNC; individuals use their 11-digit cédula.

How often is the data updated? The registry is updated regularly from the official DGII Padrón de Contribuyentes. Current data: April 2026.

Can I validate comprobantes fiscales (NCF)? This actor validates the RNC (taxpayer ID). For NCF sequence validation, you need the DGII e-CF portal. However, step 1 of any NCF validation is confirming the RNC is active — which is exactly what this actor does.

What's the difference between ACTIVO and SUSPENDIDO?

• ACTIVO: taxpayer is current with DGII obligations
• SUSPENDIDO: taxpayer has been suspended (usually for non-compliance). They cannot issue fiscal invoices until reinstated
• DADO DE BAJA: permanently deregistered
• CESE TEMPORAL: temporarily ceased operations (can reactivate)

Does this work for both companies (SRL, SAS, SA) and individuals (persona física)? Yes. The registry includes all taxpayer types: SRL, SAS, SA, EIRL, cooperatives, NGOs, and individuals (persona física).
