The DGII also keeps a separate "RNC Registrados" lookup: a taxpayer missing from one may appear in the other.
The RNC format
Companies have a 9-digit RNC; individuals use their 11-digit cédula. Enter it without dashes.
Every company at once
The lookups answer "does this company exist, and is it active?" one company at a time. For market sizing, territory planning or a prospect list you need the whole register, filtered by industry and province: Dominican Republic company data shows the counts by sector and province for free, with a 25-row sample, built from the DGCP suppliers + MICM MSMEs.
