Dominican Republic

The Dominican Republic uses the Registro Nacional de Contribuyentes (RNC) as its tax identifier framework. For natural persons with a Dominican cédula, the RNC is the cédula number; legal entities, other registered entities, and foreign individuals without a cédula receive a 9-digit RNC from Impuestos Internos.
