The classification of all self-dual codes over Z4 of length up to 15 and Type II codes of length 16 is known. In this note, we give a method to classify Type IV self-dual codes over Z4. As an application, we present the classification of Type IV self-dual codes of length 16. There are exactly 11 inequivalent Type IV self-dual Z4-codes of length 16.
