The Eight M-States — The Hardest Group

Eight states start with M, and each gets a different two-letter code. These are the most commonly confused abbreviations in the quiz:

  • MA — Massachusetts
  • MD — Maryland
  • ME — Maine
  • MI — Michigan
  • MN — Minnesota
  • MO — Missouri
  • MS — Mississippi
  • MT — Montana

The Eight N-States — Almost as Tricky

Eight states also start with N, each with a distinct abbreviation:

  • NC — North Carolina
  • ND — North Dakota
  • NE — Nebraska
  • NH — New Hampshire
  • NJ — New Jersey
  • NM — New Mexico
  • NV — Nevada
  • NY — New York

Other Abbreviations That Catch People Off Guard

Beyond the M and N groups, a few individual abbreviations don't follow the obvious pattern:

  • KS — Kansas (not KA, because KY was taken by Kentucky)
  • KY — Kentucky (K + Y from KentuckY)
  • OH — Ohio (not OI)
  • RI — Rhode Island (R for Rhode, I for Island)
  • TN — Tennessee (T + N from TeNnessee)
  • TX — Texas (T + X from TeXas)
  • CT — Connecticut (C + T from ConnecTicut)
  • WV — West Virginia (W for West, V for Virginia)

Once you've locked in the abbreviations, the state capitals quiz is a natural next challenge — and many of the same states that have tricky abbreviations also have surprising capitals.

For a broader test, the U.S. States General Knowledge Quiz mixes abbreviations, capitals, flags, birds, and nicknames in a single round.

Frequently Asked Questions

Which state abbreviations are the hardest to remember?
The eight M-states (MA, MD, ME, MI, MN, MO, MS, MT) and eight N-states (NC, ND, NE, NH, NJ, NM, NV, NY) are the most commonly confused. Within the M-states, MN (Minnesota) and MO (Missouri) trip people up most often.
Why does Kansas use KS instead of KA?
KA isn't used because the USPS assigns unique codes, and the system reserves the Y position for Kentucky (KY). Kansas takes KS — the K from Kansas and the S from KanSas.
Why does Pennsylvania use PA instead of PE?
PA comes from a traditional abbreviation used long before the USPS standardized two-letter codes in 1963. 'Penna.' was the common shorthand, which naturally produced PA.
Does the quiz include Washington, D.C.?
No. D.C. uses the code DC, but it is not a state — it's the federal district. The quiz covers all 50 states only.
Does the quiz test both directions?
Yes. Some questions show an abbreviation and ask which state it belongs to. Others show a state name and ask for the correct two-letter code. Both directions are tested.
Are the questions different each time I play?
Yes. Both the question order and the answer choices shuffle every round.
Do I need to sign up to play?
No. The quiz is free and starts immediately, no account required.
