The Mnemonic major system or phonetic number system is a mnemonic technique used to aid in memorizing numbers.

The system works by converting numbers into consonant sounds then into words by adding vowels. The system works on the principle that images can be remembered more easily than numbers.

Each numeral is associated with one or more consonants. Vowels and the consonants w h and y are ignored. These can be used as "fillers" to make sensible words from the resulting consonant sequences.

The groups of similar sounds and the rules for applying the mappings are almost always fixed but other hooks and mappings can be used as long as the person using the system can remember them and apply them consistently.

Short term visual memory of imagined scenes allows large numbers of digits to be memorized with ease though usually only for a short time.

Whilst this is unwieldy at first with practice it can become a very effective technique.[citation needed] Longer-term memory may require the formulation of more object-related mnemonics with greater logical connection perhaps forming grammatical sentences that apply to the matter rather than just strings of images.

The system can be employed with phone numbers. One would typically make up multiple words preferably a sentence or an ordered sequence of images featuring the owner of the number.

The Major System can be combined with a peg system for remembering lists and is sometimes used also as a method of generating the pegs. It can also be combined with other memory techniques such as rhyming substitute words or the method of loci. Repetition and concentration using the ordinary memory is still required.
