History and overlays

657 went into service in 2008, added to the area of 714.

714 (since 1951) shares the same area, so a new number there can get any of these codes and local calls are dialed with all 10 digits.

373 new exchanges were assigned since 2021, the latest in October 2026.

The numbering administrator is planning relief for 657: a new area code for the same area as numbers run low.
