If the user is asking in Danish about how many American states begin with the letter N, the direct answer is:

• There are four U.S. states that start with the letter N: North Carolina, North Dakota, Nebraska, and New Jersey.

Notes:

• The official two-letter postal abbreviations for these states are NC, ND, NE, and NJ respectively.
• If you’d like, I can provide quick facts for each state (capital, population, nickname) or group them by region.
