I have reverted this bulk addition as well as 138903689, 138903683, 138903673. My change sets are: 139371237, 139371294, 139371349,139371380.

As I noted here:https://community.openstreetmap.org/t/how-to-edit-the-zipcode-of-a-whole-city-or-region/101555/8 I'm sure we can find another way to get this into the DB a bit more cleanly.
