Get *city/state/zip:

For example: PO1 3AX PO refers to the postcode area of Portsmouth. PO1 refers to a postcode district within the postcode area of Portsmouth PO1 3 refers to the postcode sector.

So what do the extra numbers mean? 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 commas with places, cities, and addresses: Do you live at 115 North Street, Chesapeake, VA 23321? (There is no comma before zip code; also, there is no comma after zip code UNLESS the address appears in the middle of the sentence.)

A postal code is a set of specific numbers, and sometimes letters, that help postal services deliver mail. A five-digit number generally known as a Zip Code is important in making sure your package is delivered because it identifies a certain postal delivery area in the United States.

A ZIP Code is a postal code used by the United States Postal Service (USPS). Introduced on July 1, 1963, the basic format consisted of five digits. In 1983, an extended ZIP+4 code was introduced; it included the five digits of the ZIP Code, followed by a hyphen and four digits that designated a more specific location.

“ZIP Code” is trademarked and essentially an invention by the USPS. They created it with a capitalized “C.” Why do you insist that this “C” is rendered in lowercase? A. You are right that the United States Postal Service writes “ZIP Code” with a capital C—and ZIP in all caps.

In an address, place a comma after the street and between the city and state: 1714 North Harvey Street, Griffith, IN 46300. Do not place a comma between the state and the ZIP code.
