It’s quirky but true. Our capacity to process new information is limited. Essentially our conscious can only handle 7 plus or minus 2 bits of new information any any one time. Mobile phone numbers in Australia at least, have 10 digits. Which puts memorising them right out of the ability of most Westerners.When I was doing my Master Prac NLP with Marvin Oka, he suggested that Asian cultures because of their use of the character form of writing, actually had slightly more capacity to hold bits of information and process them. He believed unlike for most in the West it was increased to 8 plus or minus 2 bits of info at any one time.

TIP: In order for people to grasp your mobile number, you need to chunk your number into smaller amounts. For example 0411 221 025 can also be chunked 0411 22 10 25 which brings the number down to a more manageable amount of data for most people. It’s also why the whole 1-300 “flowers” concept works, because it only requires 3 bits of new of information to be stored by potential customers.
