How to Write a Michigan Address (With Examples)

Address basics  |   |  2 min read

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

The standard format

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

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

Example: Lansing

Olivia Carter 2600 River Ct Lansing, MI 48915

Example with an apartment in Detroit

Wei Garcia 1646 Liberty Way Apt 14B Detroit, MI 48221

Example with a PO Box

Andrew Jones PO Box 932 Lansing, MI 48915

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 MI with MN (Minnesota), MS (Mississippi) and MO (Missouri). These codes look similar and cause misrouted mail.
  • Writing the full state name or an old abbreviation instead of MI.
  • 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

Michigan is divided into 83 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.
