what is the current edition of the united states code
United States Code Both the LRC and the GPO offer electronic versions of the Code to the public. The LRC electronic version used to be as much as 18 months behind current legislation, but as of 2014 it is one of the most current versions available online. The United States Code is available from the LRC at uscode.house.gov in both HTML and XML bulk formats.[16][17] The "United States Legislative Markup" (USLM) schema of the XML was designed to be consistent with the Akoma Ntoso project (from the United Nations Department of Economic and Social Affairs) XML schema,[18] and the OASIS LegalDocML technical committee standard will be based upon Akoma Ntoso.[19]
ZIP Code ZIP Codes are a system of postal codes used by the United States Postal Service (USPS) since 1963. The term ZIP is an acronym for Zone Improvement Plan;[1] it was chosen to suggest that the mail travels more efficiently and quickly (zipping along) when senders use the code in the postal address. The basic format consists of five digits. An extended 'ZIP+4' code was introduced in 1983 which includes the five digits of the ZIP Code, followed by a hyphen and four additional digits that reference a more specific location.
