How to Write a Maryland Address (With Examples)

Address basics  |   |  2 min read

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

The standard format

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

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

Example: Annapolis

Linda Garcia 1067 Washington Ct Annapolis, MD 21405

Example with an apartment in Baltimore

Emily Carter 6211 Pine St Apt 11A Baltimore, MD 21206

Example with a PO Box

Grace Smith PO Box 9184 Annapolis, MD 21403

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 MD with MA (Massachusetts) and ME (Maine). These codes look similar and cause misrouted mail.
  • Writing the full state name or an old abbreviation instead of MD.
  • 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

Maryland is divided into 26 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.
