Extensive Vanity Numbers

Marketers publish the extra digits needed to complete a word even though the telephone network does not recognize digits entered after the 7th digit. For example, the “E” in 1-800-SWITCHME is a superfluous digit and is not read by the telephone network. Note: Cell phones will not process more than the 7 digits after the prefix and will return a network “fast busy” tone or some other dialing error message. If cell phones generate a high percent of incoming calls, make sure the numeric number is published under the vanity number or use only a 7-digit vanity number.
