Chunking is a process by which individual pieces of an information set are bound together into a meaningful whole.

This means that whenever you want to give out information to people, put it into groups of 2-3 words or numbers, this way they are more likely to be able to remember it. This is why companies use those “1-800-CALL-NITE” toll-free numbers to get people to remember it. This should also serve as lesson to you whenever you are giving information to consumers, give it in chunks so that they will remember it.
