How to play

  1. Press Start. You have 3 minutes for all 50.
  2. Type an answer, in any order. It counts as soon as it matches, with no need to press Enter, and fills in its row.
  3. Pause whenever you like; the list is hidden while the clock is stopped. If you leave mid-game, it waits, paused, until you come back.
  4. When the time is up, the ones you missed fill in, marked as missed.

About the codes

The Post Office introduced two-letter state abbreviations in 1963, alongside ZIP codes, so an address would fit on one line of its new machines. Before that, states had longer abbreviations of different lengths. The codes are all capitals and have no periods.

More about the codes (names some answers)

Nebraska was first given NB, but it became NE in 1969 to avoid confusion with New Brunswick in Canada. Eight states start with M, so their codes are the trickiest: ME, MD, MA, MI, MN, MS, MO and MT. Alaska is AK, Arizona AZ and Arkansas AR; Alabama is AL.

What counts

The codes are the US Postal Service’s two-letter abbreviations for the 50 states. Older short forms aren’t answers. Washington, D.C. and the territories have codes too, but they aren’t states.

Capitals, accents, spaces and punctuation don’t matter, but the spelling does.

The accepted alternative forms appear here when your quiz ends, so they don’t give any answers away.

Questions

Is DC a state code?

DC is Washington, D.C.’s code, but D.C. isn’t a state. Puerto Rico (PR), Guam (GU) and the other territories have codes too.
