If you intend to provide telecommunications services entirely within a single state (like California), you may need a separate license from a regulatory body in that state (typically, the Public Service Commission of the state). Whether or not you need a license depends on many factors, including whether the state has jurisdiction over your service, whether the state requires a license or just a registration and whether your service is provided using your own facilities or by reselling the services of another company. Although there are similarities in the way the several states regulate telecommunications services, the process is as varied as the states themselves. Some states allow a straightforward online registration for competitive services, while other states still have a public notice and hearing process. And while some states no longer require the filing of a tariff, other states not only require the tariff, they have a specific tariffing format and content requirements.
