Additional Services: Address Sequencing Services
9.3.11 Seasonal Addresses
Under all service levels, correct addresses subject to seasonal occupancy, but
which do not indicate seasonal treatment, will be identified with an “S” on cards
or a flag on address files. If the address is included in a series, such as those
used for apartment buildings, trailer parks, and seasonal delivery areas in
general, the appropriate “seasonal” indicator box is checked on the card or
flagged on the address file. When correct address cards or address files that are
not subject to seasonal occupancy but that include seasonal treatment notations
are submitted, the seasonal indicator is marked out on cards or left blank on
address files. For cards, a rubber band is placed around the card to identify it
before it is put in carrier route sequence order in the returned deck of cards. No
charge is assessed for this service.
9.4 Sequencing Cards With Blanks for Missing Addresses or Sequencing
Address Files With Missing Sequence Numbers
USPS employees at Post Offices (for cards) or the National Customer Support
Center (for address files) arrange unsequenced addresses in sequence of carrier
route delivery without charge, remove incorrect or undeliverable addresses, and,
if cards, package separately for return to the customer, and insert a blank card or
missing sequence number for address files for each existing address that is not
included in the customer’s cards or address file. (If several addresses in a series
are missing, a single blank card is inserted for the series showing the number of
missing addresses, or for address files a series of missing sequence numbers
will be omitted identifying the number of missing addresses.)
9.5 Sequencing With Address Cards or Address File Sequencing With
Addresses Added for Missing and New Addresses
9.5.1 USPS Sequencing
USPS employees at Post Offices (for cards) or the National Customer Support
Center (for address files) arrange unsequenced addresses in sequence of carrier
route delivery without charge, remove incorrect or undeliverable addresses, and,
if cards, package separately for return to the customer or, if an address file,
return as a separate file, and add new or missing addresses (including rural
address conversions to city delivery) for each existing address that is not
included in the customer’s cards or address file.
9.5.2 Separate Address Groups
Separate groups of address cards must be submitted for the addresses in each
5-digit ZIP Code delivery area: city carrier (residential addresses only); city
carrier (business addresses only); city carrier (combination of residential and
business addresses); rural and highway contract route addresses; or Post Office
box addresses (whether business, residential, or a combination). If submitting an
electronic address file, a single file meeting the same requirements is
acceptable. Each group must be accompanied by a statement showing:
a. Types of addresses (residential, business, or a combination).
b. Number of addresses on the cards or in the address file.
c. Name, mailing address, and telephone number of the list owner or agent.
