You say who you sell to in Mexico, in words. The agent turns the words into SCIAN codes, from the sector to the class, and a place, reads the directory's API with the token INEGI mails for nothing, then each company's own site.
What Belda does
It does the selling, and you say yes.
What the directory holds
INEGI, the national statistics office, keeps the DENUE, the National Statistical Directory of Economic Units. It lists establishments, not legal entities, each with its identification, its location, its economic activity and its size, so one company with several sites is several rows, and the rows of one company meet on its razón social. The directory's own front page says more than 6 million establishments in the country, from the Economic Censuses of 2024, read by the machine on 15 October 2026. Its API page says more than 5 million, undated. The industry code is SCIAN, the North American classification in its Mexican form, from a two-digit sector to a six-digit class. The API takes a token INEGI mails to the address you give, for nothing, and the directory's page offers the rows as a download too. The terms are INEGI's free-use terms: the data may be used commercially as an input to other products, with the credit Fuente: INEGI and the product's name, and any transformation of it flagged as yours, never as INEGI's.
What Belda reads
The Clase_actividad. Six digits on SCIAN, the class, under its four-digit rama, three-digit subsector and two-digit sector, the four levels the API filters by. The agent derives the class from your words, and the row's source line shows it.
The Ubicacion, the Colonia and the CP. The establishment's address with its neighborhood and its postal code, under the state, the municipality and the locality the API filters by, so a list is drawn by place.
The Razon_social and the Nombre. The company's legal name and the establishment's own name, so the several rows of one company meet on its razón social and the company stands once on your list.
The Estrato. The directory's band of staff, the one BuscarAreaActEstr filters by, so Belda shows the band, never a guess.
The Sitio_internet and the Id. The site the establishment gave, so the agent reads the company's own site next, and the directory's own Id on every row, the key its Ficha call takes.
What Belda never stores
A person's email address or phone number from the directory. Its Telefono and Correo_e fields are the establishment's contact points, and its field list names no person.
An RFC or a CURP of a person, which the directory does not serve. Its field list carries neither, only its own Id.
A row that did not come from a list you asked for. Every row names its register and its read date, or it does not enter the list.
Three questions of every row
Where did it come from. When was it true. Who said I may write to it. The directory answers the first on every row, and the day Belda read it answers the second. DENUE carries no marketing flag, so the market's rule does that work instead: Profeco's REPEP is the public registry against unwanted advertising, where a consumer lists a number so that no supplier calls or texts it, and a number on it is counted and never called. After the directory the agent reads the company's own site and marks fit with the sentence it found there and the page it was on.
What a buyer asks about Mexico's directory
Where do the Mexican companies on my list come from?
Belda reads INEGI's DENUE, the state's own directory of establishments, and never a bought database. You say who you sell to in Mexico, in words. The agent turns the words into SCIAN codes, from the sector to the class, and a place, reads the directory's API with the token INEGI mails for nothing, then each company's own site.
How many companies does Mexico's directory hold?
More than 6 million establishments, the directory's own estimate, from the Economic Censuses of 2024, read 15 October 2026.
What does Belda never store from Mexico's directory?
A person's email address or phone number from the directory. An RFC or a CURP of a person, which the directory does not serve. A row that did not come from a list you asked for.
