Toll-Free Numbers in Radio Advertising
Study Results-January, 1999
Abstract
|
Effective use of toll-free numbers can substantially increase
advertising response rates. The results of this study, focusing
on the use of toll-free numbers in radio advertising, show
that an advertisement using a toll-free vanity number (a number
that translates into words for easy recall) yields 14 times
more phone calls than an advertisement using a toll-free numeric
number. Sixty-seven percent of these calls are local calls
(originating from the same area code).

Response Rate Comparison:
Vanity toll-free numbers proved
to increase the response rate of
this radio advertising campaign.
