The DNIT publishes the whole RUC list as downloadable files rather than as a search form; it is the source of the LatSouth Paraguay file.
The RUC format
Digits plus a check digit, written 80012345-6; companies' RUCs usually begin with 80.
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 department: Paraguay company data shows the counts by sector and department for free, with a 25-row sample, built from the DNIT RUC listing.
