How to Write a Oklahoma Address (With Examples)

Address basics  |   |  2 min read

Here is how to write a mailing address in Oklahoma, with examples from Oklahoma City and Oklahoma City and the most common mistakes to avoid.

The standard format

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

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

Example: Oklahoma City

Thomas Anderson 422 Franklin Ln Oklahoma City, OK 73141

Example with an apartment in Oklahoma City

Olivia Brown 1437 Market St Apt 8B Oklahoma City, OK 73120

Example with a PO Box

Luis Wright PO Box 3957 Oklahoma City, OK 73162

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 OK.
  • 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

Oklahoma is divided into 77 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.
