The North Dakota postal code is the series of letters and numbers that can be used to sort mail or other packages sent within the state. It is similar to a ZIP code in that it helps track delivery and make sure that mail is delivered correctly. The North Dakota postal code is also called a ZIP+4 code, which means that it has four digits plus a dash, followed by two more digits. This allows for more precise tracking than just a single five-digit zip code would allow.

The North Dakota postal code was first introduced in 1967 and has not changed since then. There are 16 different postal codes that cover the entire state of North Dakota, but each one only covers part of the state’s territory. They range from 57001 to 57016 and are assigned based on where the address is located within North Dakota’s borders. The addresses are assigned so that each zip code covers roughly 200 square miles of land area.

The postal code system in North Dakota allows residents to receive their mail quickly and efficiently without having to worry about sorting through dozens of different possible destinations for their mail or packages before they even reach their destination city or town.
