How to Write a Hawaii Address (With Examples)

Address basics  |   |  2 min read

Writing a Hawaii address correctly comes down to three things: the right street format, the two-letter code HI and a ZIP code that matches the city.

The standard format

RECIPIENT NAME STREET NUMBER AND NAME, UNIT CITY, HI ZIP CODE

The state is always written as HI, two capital letters with no periods. USPS prefers the city, state and ZIP on the same final line.

Example: Honolulu

Mary Hill 4566 Sunset Rd Honolulu, HI 96826

Example with an apartment in Honolulu

Carlos Rivera 898 Park Pl Apt 16A Honolulu, HI 96813

Example with a PO Box

Jennifer Nguyen PO Box 8369 Honolulu, HI 96817

PO Boxes often have their own ZIP code, separate from street addresses in the same town. Check the ZIP with the post office that holds the box.

Common mistakes

  • Writing the full state name or an old abbreviation instead of HI.
  • Putting the apartment number on a line below the street address.
  • Using a ZIP code from a neighboring city. One city can have many codes, but each street belongs to a specific one.

Counties and local details

Hawaii is divided into 5 counties. The county does not appear in a mailing address, but it matters for sales tax, elections and some shipping rules, so many business systems store it separately.
