US address format

US Address Format Guide

A correctly ordered address is not automatically a deliverable one. Use format rules for presentation, then validate a user-supplied address through an authorized service when delivery matters.

Put the common US address fields in order.

For a simple address, place the recipient first, then the street line, then the locality line:

Avery Cedar
742 Juniper Avenue
New York, NY 10001

Put a unit designator such as Suite 120 on its own line when space permits. Keep the city, two-letter state abbreviation, and five-digit ZIP together on the last domestic line. USPS Publication 28 is the presentation reference; its conventions do not verify a person or a delivery point.

What to avoid in test data

  • Don’t portray a synthetic street line as USPS-verified.
  • Don’t treat ZIP Codes as numeric values: leading zeroes must survive imports.
  • Don’t use a synthetic record for account recovery, screening, or contact workflows.
