Check digits are designed to detect transcription and transposition errors by adding extra numbers to a code that can be used to verify its accuracy. They are not always placed at the end of a data code and their use can affect processing efficiency. While it is best practice to use check digits for important data codes, they are not necessary for all data codes.
