Unlike postal codes, which can contain a mixture of numbers and letters, zip codes only contain a combination of numeric values. Regardless of their name or structure, most countries leverage a coding system?whether a zip code, postal code, or other structure?to ensure the rapid and efficient delivery of mail to users.

?the five-digit ZIP number is a structured code in which the first digit identifies one of ten large areas of the Nation, and the second digit indicates a State, a geographic portion of a heavily populated State, or two or more less populated States.

The most complete ZIP Code is a nine-digit number consisting of five digits, a hyphen, and four digits, which the USPS describes by its trademark ZIP+4. The correct format for a numeric ZIP+4 code is five digits, a hyphen, and four digits.

These last 4 digits represent specific delivery routes within delivery areas. This extra detail means an even more precise matching to a more granular level. It could represent a handful of houses on one side of a street, or even a single building that receives a high volume of mail.

Use all-caps for ZIP and always lowercase the word code. Use the uppercase abbreviated two-letter U.S. Post Office standard for states and territories. Don't put a comma between the state name and the ZIP code.

Each subset of numbers within the zip code identifies where you live with 10 main regions of the country (numbered 0-9 at the national level), followed by two digits that identify the larger post offices where mail is sorted, and two digits for the smaller city post office that delivers to your address.

Addresses (ZIP code present) USPS abbreviations are used for both the street address and state, and there is no punctuation in the lines for the street address or city, state and ZIP code. Write to Paul and Mary Moore, 1313 E Main St, Portage MI 49024-2001.
