Use of Double- and Single-Stamped
Cards and Postcards
The users of double- and single-stamped cards and
postcards must comply with the following rules:
· Double cards must be folded before mailing.
The first half must be detached when the reply
half is mailed for return.
· The reply half on a double card must be used for
reply purposes only.
It must not be used to
convey a message to the original addressee of the
double card nor to send statements of account.
· Double cards must be prepared so that the
address on the reply half is on the inside when the
double card is mailed.
· Plain stickers, or seals, or a single-wire stitch
may be used to fasten the edges of double cards

double postcard as stated above, should not be mailed

FIRST-CLASS ZONE RATED
Zone rated mail consists of First-Class Mail
weighing more than l3 ounces and is referred to as
priority mail. Priority mail provides the fastest mail
service for heavy articles (with the exception of
Express Mail). Any class of mail can be mailed at the
priority rate of postage, if the customer is willing to pay
for this service.
WEIGHT AND SIZE LIMITS
At the time you accept an article for mailing, you
must determine whether or not it meets the weight and
size limitations. Articles mailed at the First-Class or
priority rate of postage must not exceed 70 pounds in
weight and 108 inches in length and girth combined.
Remember that First-Class rates are computed
differently for articles weighing l3 ounces or less and
for those zone rated articles weighing over l3 ounces.
First-Class zone rated (priority) rates are
computed on the basis of weight of the individual piece
and the distance it must travel. To administer these
rates, the earth is considered to be divided into units of
area 30 minutes square, identical with a quarter of the
area formed by intersecting parallels of latitude and
meridians of longitude. Each unit of area is designated
by a number. The USPS has divided the U.S. and its
territories into a local zone plus eight others. The
postal zones are defined as follows:
