The numchk tool is a command-line tool that identifies self-consistent numbers and checks their correctness. In short, it is like file(1) for numbers. The focus is on fast bulk processing of identifiers arising primarily in the financial sector. Unlike similar libraries numchk only provides syntactic and first level semantic checks (mostly check digits and country code validation) in order to identify and disambiguate the input. Deep semantic verification, aspects of formatting and canonicalisation are left to its competitors.
