Washington Utilities and Transportation Commission
Regulated telecommunications companies must file tariffs - a document outlining rates, terms and conditions for providing service - with the UTC describing their monopoly services and must ask for approval of any changes. Many companies also maintain electronic versions of tariffs on their own websites.
Competitive telecommunications companies usually describe their services in a catalog. These catalogs are also usually available on the company's website.
For paper copies of tariffs on file with the UTC, search our Online Library, fill out a Public Records Request, or call 360-664-1166.
A number of telecom companies' tariff websites are listed below.
