Federal Information Processing Standards (FIPS) Codes for the Identification of the States, the District of Columbia and the Outlying Areas of the United States, and Associated Areas, Publication #5-2, May, 1987, may be used for 'state' codes.

DSMO Category
Approve. While DSMO agrees that code source references do need to contain current information, selection of specific code sources must be done in coordination with all other Subcommittees within X12 to meet cross industry needs. X12N will pursue updating the code source reference to reflect the current distribution of the code set by the US Postal Service.
