In many countries, local addresses consist of zip codes, postcodes, a series of letters, numbers, and occasionally spaces or punctuation used to sort mails and packages. Residents of the United States utilize a system of postal codes also known as zip codes.

The United States Postal Service (USPS) uses zip codes to deliver mail to addresses nationwide, while people in the United Kingdom, Canada, Australia, and many other countries use postcodes.

Zip codes are five-digit numbers that help people in the United States find specific places. The first three digits show a region, and the last two show a more specific place within that region.
