Zip Codes of the United States
ZipCodeLookup.co
Visit ZipCodeLookup.co to find zip codes by address, city, county or state.The ZIP code, introduced on July 1, 1963, by the United States Postal Service, extended the existing two-digit postal code in major cities to help manage the increasing use of direct mail by businesses. Its primary aim was to enhance mail processing efficiency and accuracy, addressing the labor shortage resulting from World War II by providing a straightforward system for training new workers.
The first digit of the 5-digit ZIP code signifies the region, with "0" for the Northeast and "9" for Alaska. The next two digits identify a central mail processing facility (SCF) within that region, while the final two digits pinpoint smaller post offices or specific zones in larger cities.
