SinceFor all checksum algorithms including the Damm algorithm, prepending leading zeroszeroes does not affect the check digit,<ref name="fenwick2014" /> variableso length codes should not be verified together since, e.g., 01, 01, and 001, etc. produce the same check digit. However,Consequently allvariable checksumlength algorithmscodes areshould vulnerablenot tobe thisverified together.
