The business directory searched by name

The search runs across the SIEM directory (Sistema de Información Empresarial Mexicano) as a partial, case-insensitive name match: typing OXXO returns every branch registered under that name. Each result carries the commercial name, the chamber that enrolled the establishment, the state with its INEGI code, and the id you use to open its full record, where the RFC, address, contact, headcount and foreign-trade profile live. The state and SCIAN activity filters exist to cut long lists down: a national chain can have hundreds of branches enrolled. Bear in mind that enrollment is voluntary, so this directory is good for locating and contacting establishments, not for concluding that a company does not exist because it is not listed.

  • Name matches

    Commercial name or legal name, matched partially and without case sensitivity.

  • State and activity filters

    INEGI state code and SCIAN activity code to narrow down a long list.

  • Id for the full record

    Each establishment's id, which opens its complete record in SIEM.

Common questions

A fragment is enough: the search matches partially and ignores case. Two characters minimum. The more specific the name, the less noise in the list.

The INEGI state code, 1 through 32 (for example, 21 for Puebla). Leave it at 0 to search the whole country.

Because enrollment in SIEM is voluntary: not every company signs up, and those that do register under the name they chose, which is not always the one the brand uses. Try a variant of the name, or the legal name.
