Advantages:

-Storing less information therefore less memory is required

-If the codes are not apparent then it is difficult to know and understand the meaning of the codes

-The codes take less time to enter therefore it is quicker to input large amount of data

-Since the codes follow a strict set of numbers and letters they are easy to validate

Disadvantages:

-precision of data coarsened

-If codes are made up of a range of letters and numbers the options will be limited

-Validation will ensure the code is entered correctly but the nature of the code will make it difficult to see if the code is actually correct
