South Carolina Zip Codes



South Carolina South Carolina is a state in the Southeastern United States. It is bordered to the north by North Carolina; to the south and west by Georgia, located across the Savannah River; and to the east by the Atlantic Ocean. Originally part of the Province of Carolina, the Province of South Carolina was the first of the 13 colonies that declared independence from the British Crown during the American Revolution. The colony was originally named by King Charles II of England in honor of his father Charles I (Carolus being Latin for Charles). South Carolina was the first state to ratify the Articles of Confederation, the 8th state to ratify the US Constitution on May 23, 1788. South Carolina later became the first state to vote to secede from the Union which it did on December 20, 1860. It was readmitted to the United States on June 25, 1868.

South Carolina is the 40th most extensive and the 24th most populous of the 50 United States. South Carolina comprises 46 counties. The capital and largest city of the state is Columbia.

ZIP codes are a system of postal codes used by the United States Postal Service (USPS) since 1963. The term ZIP, an acronym for Zone Improvement Plan, is properly written in capital letters and was chosen to suggest that the mail travels more efficiently, and therefore more quickly, when senders use the code in the postal address. The basic format consists of five decimal numerical digits. An extended ZIP+4 code, introduced in the 1980s, includes the five digits of the ZIP code, a hyphen, and four more digits that determine a more precise location than the ZIP code alone. The term ZIP code was originally registered as a servicemark (a type of trademark) by the U.S. Postal Service, but its registration has since expired.

ZIP codes designate only delivery points within the United States and its dependencies, as well as locations of its armed forces. There are no ZIP codes reserved for designating mail bound for foreign destinations (with the exception of U.S. military units stationed outside of the United States), and therefore, international outbound mail should not include a ZIP code in the delivery address. The last line of a foreign address must only show the name of the country of destination.
