Data point: Minor requiring new application. Went to USPS in 33707 on 12/24 and was told the application was incomplete because we were missing our marriage cert.
Set a new appointment in 95008, USPS said we didn't need marriage certificate and that person was wrong since we look like the parents. YMMV I suppose.
