Frontier Communications Northwest, Inc., has won an end to rate regulation, arguing sufficient competition exists between telecom companies in Washington State to make the oversight unnecessary.

The Washington State Utilities and Transportation Commission approved the request this week, adding it would allow more pricing flexibility for Frontier services in the state.

Although the majority of Washington is served by CenturyLink, which acquired the assets of Qwest, Frontier has 321,000 customers in Redmond, Kirkland, Everett, Bothell, Woodinville, and other smaller communities. Most of Frontier’s customers were acquired from Verizon Northwest in 2010 after the company exited the landline business in the state.

Frontier must still adhere to Washington’s consumer protection laws. Customers with unresolved problems with Frontier services, including its adopted FiOS fiber network, can call the Commission’s HelpLine at 1-888-333-9882.
