CLUSTER WEB-BRAZILIAN-REGISTRATION · 14 ENTRIES · EARLIEST ENTRY 2026-08-11

Brazilian tax ID lookup tools

The cluster consists of web tools for looking up and validating Brazilian tax identification numbers (CPF, CNPJ, IE), including verification, enrichment with supplementary web data, and generation of valid test samples for QA teams. The dated history is too thin to read a shape from — only one pre-index entry exists, and several members are undated. All three traction leaders (search-cnpjs, Identifications, and Brazilian CNPJ Consult Tool) show zero stars, so no member clearly leads on activity.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
