How do I check a supplier in Argentina?

Ask the supplier for its CUIT, the tax ID, and read it against the official lists. Testigo holds 1 lists for Argentina that are read by CUIT: Base de facturas apócrifas (APOC) (ARCA, 2026-10-03, 22,564). Each list shows its publisher and edition date. An empty result is not a clean bill of health: it covers those lists and editions only.
