Norðdepil was founded in 1866. Its school opened in 1895. From 1897 to 1912 a whaling station was located in the community, built by Norwegians. The first owners were Andorsen & Neumann.
Norðdepil has been connected with the town of Hvannasund on Viðoy by a road on a dam since 1963. Because the two communities are located directly across from each other on opposite shores, they often act as one community.
Since 1967, two single-lane tunnels have connected Norðdepil with the regional city of Klaksvík.
Immediately bordering Norðdepil to its north is the abandoned settlement Fossá, of which nothing remains. Fossá was named after some waterfalls.
Further north on the east coast of Borðoy there is a road going from Norðdepil to the hamlet Múli.
