Can phone numbers or Web addresses be included?

The FCC has indicated that location information, including phone numbers and Web addresses, are acceptable to identify an underwriter.  While it seldom makes sense to use physical addresses for national air, PBS does allow phone number and/or Web address, typically in fonting only.  Stations can use their own judgment on this (with appropriate legal counsel), and in some cases it may be acceptable to voice this information.  However, regardless of the way a phone number and website is represented, viewers cannot be urged to call or visit, and PBS does not allow these numbers or URLs to spell out something that is not acceptable to say otherwise, e.g., 1-800-THEBEST,
