# What is SCIAN?

SCIAN is Mexico's version of the North American industry classification. DENUE gives every establishment a six-digit SCIAN code, and manufacturing is the set of codes that start with 31, 32 or 33. Testigo maps SCIAN to the same sector list as the other countries, and shows the code as INEGI wrote it.
