3-digit postal code USA 2016

Postal codes in the United States of America are known as ZIP-codes. ZIP-codes are used to help the United States Postal Service (USPS) route mail more efficiently throughout the country and large cities like New York. A USPS postal code identifies an individual post office or metropolitan area delivery station associated with mailing addresses. However not everywhere in the US is assigned a postal code. Some regions, especially remote and rural areas have too little deliverable addresses to create a mail route.

USPS ZIP-codes are not actually spatial features. The United States Census Bureau developed the so called ZIP code tabulation areas (ZCTAs). They are a spatial representation of the US ZIP-codes and are often used to depict statistical data about regions. This map depicts the boundaries of all 3-digit ZIP-code tabulation areas in the US.
