HALLOWELL, Maine (AP) — Utility regulators in Maine are opening an investigation into the numbering practices of wireless giant T-Mobile as the state runs out of available phone numbers within its sole area code. The Maine Public Utilities Commission has said the 207 area code is predicted to run out in the final quarter of 2025. Commission Chair Philip Bartlett said Wednesday the T-Mobile investigation is part of the state’s effort to extend the life of the area code as long as possible. The commission said in a statement that it has questions about T-Mobile’s forecasting process for numbering resources. T-Mobile did not immediately respond to a request for comment.
