Limit: it says the site answered that day and nothing about the plant. - Certificates named on its website: names such as ISO 9001, IATF 16949, AS9100, ISO 14001 and ISO 13485 found on the plant’s own site. Limit: a claim by the plant, not a confirmation. Never report it as a certificate the plant holds. - Email domain accepts mail: the domain of the published email address has mail servers, with the date. Limit: it does not show that the address exists. - Totals as of 2026-10-12: 88,868 websites checked, 79,232 responded, 4,448 plants name a certificate, 560,751 email domains checked, 542,361 accept mail. - Method and limits: https://testigomexico.com/coverage#checks ## Limits: what Testigo does not do - Testigo does not audit plants and has not visited any plant. - It does not confirm certificates. A certificate found on a plant’s own website is shown as named on its website: the plant’s claim. - It does not check capacity, quality or financial health. No public registry holds them. - A record repeats what the registry said on its edition date. A registry can hold units that have closed or moved. - Countries are not directly comparable: each registry has its own unit, its own activity codes and its own rule for what is active. - A tax ID check that finds nothing covers the lists and editions named in the result, and nothing else. - Testigo gives no legal or tax advice. ## Method, and how to cite - How records and counts are made, what each lamp means and what is not checked: https://testigomexico.com/methodology - Cite the registry and its edition through Testigo: "Testigo, from , edition ,
". Example: "Testigo, from INEGI DENUE, edition 2026-05-20, testigomexico.com/statistics/mexico". - Use the count and the edition date shown on the page you read. Counts change when a registry publishes a new edition. - A lit lamp means the registry holds an item. It is not an approval of a plant. ## Open data and plain-text versions - Data files (JSON and CSV, aggregate counts only, open to any origin): https://testigomexico.com/data. Catalogue: https://testigomexico.com/data/index.json - Every key page has a Markdown version at its address plus ".md", for example https://testigomexico.com/statistics/mexico.md, https://testigomexico.com/pricing.md, https://testigomexico.com/features.md, https://testigomexico.com/methodology.md, https://testigomexico.com/manufacturers/mexico.md ## Key statistics (data file generated 2026-10-12) Counts of rows in the official registry of each country, as loaded by Testigo, computed from the same extract that is loaded into the search.

When you export a search, its plants are also saved as a list named after the search. Each plant has a status and a note, so the list is where you follow up. A weekly summary by email says who is left to contact on each list. It is off until you turn it on, and one click stops it. When a registry is loaded again, the app shows which plants are new on a saved search and which plants on a list changed. - 2026-10-12: Taiwan is in the app. Manufacturers in Taiwan are now in the app search, read from the business tax registration file of the Fiscal Information Agency, Ministry of Finance. It is the first country outside Latin America. Names and addresses are in Traditional Chinese, as the registry writes them. Activity names are translated. The file has no phone, email, website or coordinates, and it gives registered capital, not staff. Only legal entities are loaded. The coverage page shows the source, its edition and its licence. - 2026-10-12: List status, saved comparisons, several regions and feedback. Each plant on a list has a status: to contact, contacted, replied or rejected. A comparison can be saved under a name, reopened and shared as a link. The state or region filter takes several regions at once, with two ready sets for Mexico: the border states and the Bajío. A record shows more facts where the registry holds them: secondary activities, share capital, legal form, programme and exporter lists, distances to the nearest port, airport and border crossing, and similar plants nearby with the count the linked search returns. Send feedback from any page, or say that a record is wrong in one tap. A new page lists what we are building next, and accounts vote on it in the app. - 2026-10-12: Launch offer, and one list on Free. Launch offer: subscribe by November 30, 2026 and Pro costs 30% less for the first 12 months, $34.30 a month on the monthly plan. It is applied at checkout, with no code. After the trial, a Free account keeps one list: its oldest, up to 25 plants. You can still save plants to it and edit notes and status. Contacts, export and more lists are part of Pro. - 2026-10-07: Product tour, features page and statistics. The home page has a product tour: search, a record, a list, compare and the supplier brief, shown as an example recorded from the live search. A features page says what each part does and what is in Free and in Pro. Three pages speak to sourcing, supplier quality and research teams. Statistics pages give the number of manufacturers by country, region and sector, with the registry, its edition and a CSV file to download. A methodology page says how each count is made. Without an account, a search now shows the count, the split by country and industry, and a preview of 3 rows. ## Markdown versions of the key pages - https://testigomexico.com/features.md - https://testigomexico.com/for/sourcing.md - https://testigomexico.com/for/supplier-quality.md - https://testigomexico.com/for/research.md - https://testigomexico.com/for/sales.md - https://testigomexico.com/methodology.md - https://testigomexico.com/compare.md - https://testigomexico.com/guides/public-record-mexico.md - https://testigomexico.com/guides/public-record-brazil.md - https://testigomexico.com/guides/public-record-argentina.md - https://testigomexico.com/guides/public-record-colombia.md - https://testigomexico.com/guides/public-record-peru.md - https://testigomexico.com/guides/public-record-chile.md - https://testigomexico.com/guides/public-record-ecuador.md - https://testigomexico.com/guides/public-record-paraguay.md - https://testigomexico.com/guides/public-record-uruguay.md - https://testigomexico.com/statistics.md - https://testigomexico.com/statistics/mexico.md - https://testigomexico.com/statistics/brazil.md - https://testigomexico.com/statistics/argentina.md - https://testigomexico.com/statistics/colombia.md - https://testigomexico.com/statistics/peru.md - https://testigomexico.com/statistics/chile.md - https://testigomexico.com/statistics/ecuador.md - https://testigomexico.com/statistics/paraguay.md - https://testigomexico.com/statistics/uruguay.md - https://testigomexico.com/manufacturers/mexico.md - https://testigomexico.com/manufacturers/brazil.md - https://testigomexico.com/manufacturers/argentina.md - https://testigomexico.com/manufacturers/colombia.md - https://testigomexico.com/manufacturers/peru.md - https://testigomexico.com/manufacturers/chile.md - https://testigomexico.com/manufacturers/ecuador.md - https://testigomexico.com/manufacturers/uruguay.md - https://testigomexico.com/pricing.md - https://testigomexico.com/data.md - https://testigomexico.com/questions.md ## Contact - A form, for questions, for a record that is wrong and for requests to correct or remove a company record: https://testigomexico.com/contact.
