The acronym CUSIP typically refers to both the Committee on Uniform Security Identification Procedures and the 9-character alphanumeric security identifiers that it distributes for all North American securities for the purposes of facilitating, clearing, and settlement of trades. This number is not the Federal Identification Number for a company.

A CUSIP number identifies most securities, including stocks of all registered U.S. and Canadian companies, and U.S. government and municipal bonds.
