Pieces Bearing Attachments
Updated January 2001
discusses whether a postcard mailed at the card rate
may bear an attachment.
To qualify for mailing at the card rate, Domestic
Mail Manual (DMM) 201.1.2* states that postcards (i.e., cards
not supplied by the USPS), must be rectangular in shape and not less
than 0.007 of an inch thick. Other requirements for the minimum and
maximum length and height dimensions apply as stated in DMM
201.1.2. Postcards must be of uniform thickness and made of
unfolded and uncreased paper or card stock of approximately the same
quality and weight of stamped cards. Postcards may be formed of one
piece of paper or card stock, or two pieces of paper that are
permanently and uniformly bonded together.
Postal standards provide that matter which is in the
form of a card, but does not conform to the physical standards for
the card rate, may not be mailed at the card rate. Such
nonconforming matter is subject to postage at the applicable rate
for matter other than cards (i.e., letters, flats, parcels).
A question was raised about a card that had a
photograph held to it under a plastic cover by a laminating
process. Cards so prepared do not qualify for mailing at the card
rate because they bear attachments, they are not prepared entirely
of paper or card stock, and they are not of a uniform thickness.
Pieces that do not qualify for the card rate are subject to the
applicable First-Class Mail or Standard Mail rates of postage. The
Standard Mail rates may only be claimed if the content of the
mailpiece is eligible for the applicable Standard Mail rate as
specified in DMM 243*.
