CodeBank is a permanent repository for every codified version of an online code. Each time the online code is updated, the previous version is archived in the CodeBank repository.
If you only see the current version, CodeBank has just been turned on for this publication. Rest assured that after the next update to the code, the drop down will begin to show archived versions.
If you are a municipal government user and would like to populate CodeBank with prior code versions instead of waiting for your next update, please contact our Sales Department at 1-800-262-2633 or email@example.com for more information.
