Which abbreviation is used for the North direction?

The abbreviation used for the North direction is "N." This letter is derived from the word "North" itself, and it is widely recognized in navigation, mapping, and geospatial contexts. When indicating direction, "N" serves to clearly communicate to individuals where to orient themselves when reading maps or following directions.

In contrast, other options such as "E" represent East, "Frt" stands for freight (usually referring to goods transport), and "Psgr" denotes passenger. None of these relate to directional indicators like North does. The clarity and universal understanding of "N" make it the standard abbreviation for North in transportation and other navigational references.
