The Science behind Memorable 800 Numbers

Our research indicates that 25 to 69% more calls are generated using memorable 800 numbers versus random or non-memorable ones.

The Science behind Memorable 800 Numbers:

In 1954 Dr. George Miller of Princeton University wrote a landmark paper that demonstrated how people can only remember a very few things in their active or working memory.

He called his principal Memory Chunking. Dr. Nelson Cowan of the University of Missouri published an update of Dr. Miller’s study in the Psychological Review in 2002. Cowan determined that people can only remember three or four things in their active, temporary, short-term or working memory (all synonymous).

This is very exciting research that applies beautifully to advertising with toll-free numbers. As Malcolm Gladwell writes in Outliers, most Americans only have about a two second memory loop.

This means that people can only recall things for a very short period of time. In order to aid our memory we have to chunk the information – it’s how we organize information. Therefore a number that is highly “Chunkable” — ideally up to three different chunks — increases the likelihood that people will call. At Dial800 we’ve studied this and found it to be true. Our research indicates that 25 to 69% more calls are generated using memorable numbers versus random or non-memorable ones. Next time you advertise, and REALLY want people to call you, please, only use memorable numbers and you too will profit from the science of Number Chunking.
