The SRI covers every taxpayer; the Supercias covers corporations (S.A., Cía. Ltda., S.A.S.) and is where their filings and financial statements live.
The RUC format
13 digits ending in 001. Private companies have a 9 as the third digit.
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: Ecuador company data shows the counts by sector and province for free, with a 25-row sample, built from the SRI Catastro RUC.
