If you’d like to remove some in use Patron Address Types, this UNTESTED script might be able to help. You should test this thoroughly on a non-production system before running!
*Note: Sadly, these are called AddressTypeIDs in one table and AddressLabelIDs on another table 
The IDs you’ll need for this script come from the following table:
-- ***** IMPORTANT SAFEGUARDS *****
-- 1. ALWAYS BACK UP your database or at least the [PatronAddresses] table before running mass updates.
-- 2. TEST this script thoroughly in a non-production (test/development) environment first.
-- 3. REVIEW the row count output carefully after execution.
