Ruling discusses the
use of unauthorized endorsements.
"Postmaster If There are Two or More Catalogs for the Same Family,
The Return of the Duplicate Catalog is Requested" is not an approved
endorsement that is recognized by the Postal Service.
Only the authorized
endorsements listed in Domestic Mail Manual (DMM) 507.1.5.3 may be
placed on Standard Mail pieces. Unauthorized endorsements should
not be placed on mailing pieces. If such endorsements are used,
postal employees are not obligated to honor them.
