Use U.S. Postal Service style for mailing addresses. Use AP style in text. In other applications, such as invitations, posters and tables in reports, accommodate readability.

Addresses in text

When to abbreviate versus spell out: 

  • In expository text, only avenue, boulevard and street are abbreviated (Ave., Blvd., St.) and only when used as part of a numbered street address.
  • All other street suffixes (drive, road, alley, etc.) are spelled out in all instances.


  • Capitalize a street suffix when part of a street name without a number, but don’t capitalize it when used alone or with two or more street names: Mill Avenue, Rural and Baseline roads.

Figures or numbers?

  • Use figures for address numbers.

When to spell out numbers:

  • Spell out and capitalize First through Ninth when used as street names; use figures and ordinals for 10th and above.

Superscript, th or th:


  • Meet me on the northeast corner of Hickory and Walnut boulevards.
  • Dupont Circle is a traffic circle, park neighborhood and historic district in Washington, D.C.
  • My office is at 7 Fifth Ave. and his is at 100 21st St.
  • Send your inquiry to: Admission Counselor, Arizona State University, 100 University Way, Lake Havasu City AZ 86403.

Mailing addresses

When showing an address in the block style of a mailing address or in usage that could prompt a reader to consult a GPS device (as within a footer), conform to the U.S. Postal Service address standards.

  • Use a specific line order, as shown in the example below.
  • Do not use punctuation on any line, including between city, state and ZIP code.
  • Use specific abbreviations for street suffixes (refer to the USPS comprehensive list of suffix abbreviations).
  • U.S states: Use the USPS two-letter abbreviations (uppercase, no periods) when addressing correspondence for mailing, using full addresses, including ZIP code. See format sample below.
  • ASU campus addresses follow the same line order as the U.S. Postal Service standards.

ASU address example:

Person Name
Department Name
Arizona State University
City State ZIP+4

External address example:
