U.S. Address Format Guide

A common U.S. address is written from the most specific delivery detail to the broadest location. For most web forms, that means a recipient name, street address, optional apartment or suite, city, two-letter state abbreviation, ZIP Code, and country.

The second line may contain an apartment, suite, unit, floor, department, or room number. Some systems store this in a separate Address Line 2 field, while others keep it after the street line.

Core fields in a U.S. address

• Recipient name: the person or business name shown on the address.
• Street line: house number, street name, and street type such as St, Ave, Rd, Blvd, Dr, or Ln.
• Secondary unit: Apt, Suite, Unit, Floor, Room, or a hash-style unit such as #204.
• City and state: the city name followed by a two-letter state abbreviation.
• ZIP Code: usually five digits, with optional ZIP+4 for more detailed routing.

Common variants to test

Form QA should include more than one address shape. Useful variants include no unit, Apt or Suite, PO Box, rural route, long street names, short city names, and ZIP+4 values. These variations help reveal layout, validation, import, and export problems.
