The problem with bought lists
You sell lubricants, tooling or machining to factories. You need every plant in your territory that fits, not the rows a list seller chose. Bought lists are old, and nobody says where a row came from.
Testigo loads every manufacturing row of the official registry. Each plant carries its source and its edition date, so you know how fresh the list is.
How to build a territory list
- Pick the industry and segmentChoose an industry, then a segment such as Machining or Tools, dies and moulds. Or type a product or a process in your own words.
- Add your statesPut several states or regions in one search. In Mexico, one tap adds the six border states or the Bajío.
- Keep IMMEX plantsIf you sell to exporters, the programme filter keeps Mexican plants matched to an IMMEX or PROSEC programme. It is part of Pro.
- Set a sizeMexico's registry counts staff. Brazil publishes a size class by revenue. Testigo says which is which.
- Save and exportSelect the plants on a page and save them to a list. Export the list as CSV: name, activity code, state and municipality, with the phone, email, website and address where the registry publishes them.
What comes in the file
| Country | With a phone | With an email |

| Mexico | 270,308 | 72,678 |
| Brazil | 540,143 | 487,732 |
For IMMEX plants by state, see the IMMEX directory.
What the registry does not hold
- No contact person. A registry names the company and the plant, not the buyer or the maintenance manager.
- No machines, brands or volumes. The activity code says what a plant makes, not what it buys.
- No revenue for a plant. Size is staff in Mexico and a class by revenue in Brazil.
- A phone is the one the plant gave the registry. Testigo has not called it.
How each count is made is on the methodology page.

Frequently asked questions
Can I export a list of plants with phone numbers?
Yes, with Pro, where the registry publishes them. Save the plants to a list and export it as CSV. The file carries the phone, email, website and address on each record. In Mexico 270,308 records hold a phone. The registries of Argentina, Peru, Chile and Paraguay publish no contacts.
Can I search several states at once?
Yes. Add as many states or regions as your territory holds to one search. In Mexico, shortcuts add the six states on the US border or the four Bajío states in one tap. Each country uses its own regions, as its registry names them. Combine them with an industry, a segment and a size.
Does Testigo show who to call at the plant?
No. Official registries name the company and the plant, with a general phone or email where they publish one. They do not name a purchasing or maintenance contact. Use the list to plan the territory and make the first call, then keep your own contact details and notes on each plant in the list.
