FAQ

Questions buyers ask first.

Is Testigo free?

Search is free and open to anyone, with a preview of 3 results. An account is free too, and starts with 14 days of Pro, with no card. After that it stays on Free, or you subscribe to Pro for $49 a month. Pro opens every result, contacts, lists and export.

Where does the data come from?

Every plant comes from an official public registry, such as the DENUE directory published by INEGI in Mexico. Each record names its source and the edition we read. The coverage page lists every source, with its publisher, its date and the number of rows loaded.

Do plants pay to appear?

No. Plants never pay to appear and cannot pay for position. A plant is in Testigo because an official registry lists it. Results are ordered by how well they match your words, and by nothing else. There is no paid listing, no badge for sale and no sponsored result.

Does a green lamp mean a plant is approved?

No. A lit lamp means the registry holds that item, for example a phone number or coordinates. Testigo does not audit plants. Certificates, capacity, quality, financial health and site visits are not checked, and each record says so. Testigo also runs three checks of its own, each with its date and its limit.

Which countries are covered?

Testigo covers 9 countries in Latin America today: Mexico, Brazil, Peru, Argentina, Colombia, Chile, Ecuador, Paraguay, and Uruguay. Each one comes from its own official registry, read as published. The coverage page shows every source, its edition date and the number of plants loaded. Countries with no usable public source are listed there too, with the reason.

What if a record is wrong?

A record repeats what the registry says on the edition date. If the registry is wrong or out of date, the record will be too. The source and edition are on every record so you can check it. Corrections belong with the publisher of the registry. If the record of your own company is wrong, tell us through the contact form.
