A “phone number for ww” specifies a dedicated telephone contact for the internet service “WorldWideWeb” (or “www”). For instance, the former U.S. main support line for www was (800) 638-6591.
Phone numbers for internet services provide convenient direct contact options, centralizing support and streamlining communication. A notable development in phone number allocation occurred in 1989, when the North American Numbering Plan Administration created the “800” prefix for toll-free numbers in the United States, making phone support more accessible.
