How to Write a Indiana Address (With Examples)

Address basics  |   |  2 min read

A correctly written Indiana address helps mail and packages arrive on time, and it keeps your databases clean. This guide covers the format with real city and ZIP examples.

The standard format

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

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

Example: Indianapolis

Matthew Green 1876 Summit Blvd Indianapolis, IN 46214

Example with an apartment in Indianapolis

Ashley Hernandez 9817 Laurel Dr Apt 16 Indianapolis, IN 46282

Example with a PO Box

Emily Hill PO Box 4700 Indianapolis, IN 46278

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

  • Mixing up IN with IA (Iowa) and ID (Idaho). These codes look similar and cause misrouted mail.
  • Writing the full state name or an old abbreviation instead of IN.
  • 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

Indiana is divided into 94 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.
