Area code/prefix search

Search by area code/prefix (NPA/NXX) or OCN

  • Effective date searches are available only for US area codes. Our sources for non-US NPA-NXX data do not provide this information.
  • If you want to search an entire area code regardless of activity, leave both the next and past days fields set to zero.
