## Check one supplier, and keep a dated record of it URL: https://testigomexico.com/for/supplier-quality Updated: 2026-10-07 Testigo shows what the public record says about one supplier in Latin America: its registry entry, its tax ID where the registry publishes one, and whether any of 15 official lists names it. Each line carries its publisher and edition date, and the supplier brief saves it as a PDF. Key facts: - Official lists held: 15 - Tax ID check: Mexico (RFC), Brazil (CNPJ), Colombia (NIT), Argentina (CUIT) - SAT Article 69-B: 11,241 rows, edition 2026-08-31 - CEIS, Brazil: 9,633 rows, edition 2026-10-02 - Document for the file: Supplier brief, one or two pages, PDF ### The question you are asked Someone proposes a supplier in Mexico or Brazil. Before it goes on the approved list you need to show that the company exists, that it is active, that no tax or sanction list names it, and when you looked. Each of those lives on a different government page, in a different format, in another language. Testigo reads those sources and puts them on one record, each with the date of the edition it read. It does not replace your audit. It gives you the public part, dated, so the audit starts from facts. ### What Testigo gives a quality or compliance team - The registry entry: name, legal name, activity code, status, place and size, as the registry writes them, with the edition date. - The tax ID where the registry publishes one. Brazil, Argentina, Colombia, Peru, Chile, Ecuador, Paraguay and Uruguay do. Mexico's plant registry does not. - A tax ID check against the official lists of four countries, each with its publisher and edition. - Programme entries on the record, such as an IMMEX programme and its status in Mexico. - Testigo's own checks, each with its date: the website responded, certificates the plant names on its website, the email domain accepts mail. - A supplier brief with a source and a date on every line, and the gaps listed with what to ask the plant. ### The lists behind the check | Country | Key | Lists read | Guide | | --- | --- | --- | --- | | Mexico | RFC | SAT Article 69-B, 69-B Bis and five lists under Article 69 | The SAT 69-B list | | Brazil | CNPJ | CEIS, CNEP and the register of employers | CEIS and CNEP | | Colombia | NIT | DIAN's list of proveedores ficticios | The DIAN list | | Argentina | CUIT | ARCA's base of apocryphal invoices (APOC) | The APOC list | Row counts and edition dates for every list are on the check pages and on the coverage page. Natural persons are dropped from every list. Mexican plants come from DENUE, which has no RFC. So no SAT list is attached to a Mexican plant record. Ask the plant for its RFC and run the check with it. ### One supplier, start to finish 1. Find the company: Search by name and open the record. Note the registry, the publisher and the edition date. 2. Read the status: The status is shown in the registry's own words. The guides explain what active means in each country. 3. Run the tax ID check: Use the tax ID on the record, or the one the supplier gave you. Testigo names each list it read and the edition of each. 4. Read the limits: The record names what was not checked. Add those points to your audit plan. 5. File the brief: Open the supplier brief and save it as a PDF. It carries the date you read it. ### What the check does not cover - An empty result is not a clean bill of health. It covers the lists and editions shown, and nothing else. - A listing is a reason to ask questions and to take advice. It is not proof of wrongdoing. - Certificates are not confirmed with the issuing body. Ask for the certificate and check it there. - No sanction list is loaded for Chile, Ecuador, Paraguay or Uruguay. - Testigo gives no legal or tax advice. ### Questions **Can I check a Mexican supplier against the SAT 69-B list?** Yes, by RFC. Testigo holds the legal entities of SAT's Article 69-B list, 11,241 rows in the edition of 2026-08-31, and six more SAT lists. Mexico's plant registry carries no RFC, so ask the supplier for it and enter it in the check. A name match alone is not safe. **What does the supplier brief contain?** One record on one or two pages: what the plant makes, the company and its status, contacts, export programmes, list entries, Testigo's own checks and the location. Every line names its source and its date. The last section lists what no registry shows, with what to ask the plant for each point. **How current are the lists?** Each list shows the edition date Testigo read, and the check names that date in its result. Publishers update on their own rhythm, so a list can be newer on the publisher's page than on Testigo. For a decision that depends on it, read the publisher's current list as well. **Is a clear result an approval of the supplier?** No. A clear result means the lists Testigo holds, in the editions shown, do not name that tax ID. It says nothing about quality, capacity, finances or conduct outside those lists. Testigo never calls a plant approved. The record shows what was checked and what was not.
