a. Periodicals matter is forwarded only to domestic addresses.

b. Publications with an alternative addressing format under 602.3.0 are delivered to the address when possible. Forwarding service is not provided for such mail. Periodicals publishers are notified only when mailpieces with the occupant or exceptional address formats are undeliverable for solely address-related reasons.

d. Address correction service is mandatory for all Periodicals publications, and the address correction service fee must be paid for each notice issued.

ACS participants may receive the change notice before day 60, if so requested. Copies received after the address correction notice is mailed are disposed of by the USPS. When copies of the publication cannot be forwarded, the address correction notice is prepared for the first undeliverable issue of the publication received. Forms 3579 are mailed to publishers at least once a week.

The publisher may request the return of copies of undelivered Periodicals by printing the endorsement "Address Service Requested" on the envelopes or wrappers, or on one of the outside covers of unwrapped copies, immediately preceded by the sender's name, address, and ZIP+4 or 5-digit ZIP Code. This endorsement obligates the publisher to pay return postage. Each returned piece is charged the single-piece First-Class Mail rate for the weight and shape of the piece, and the nonmachinable surcharge if applicable, or the Priority Mail rate for the weight and destination of the piece. When the address correction is provided incidental to the return of the piece, there is no charge for the correction.

b. The exceptional address format under 602.3.0 may not be used on mail with any ancillary service endorsement or mail with any extra service. Forwarding service and address correction service are not provided for undeliverable Standard Mail with this address format.

c. The endorsement "Change Service Requested" is not permitted for Standard Mail containing hazardous materials under 601.10.0. Standard Mail containing hazardous materials must bear the endorsement "Address Service Requested," "Forwarding Service Requested," or "Return Service Requested."

d. Standard Mail can be forwarded or returned at the appropriate Media Mail or Library Mail rate if the content of the mail qualifies as Media Mail under 173, 373, or 473 or Library Mail under 183, 383, or 483 and the mail is marked "Media Mail" or "Library Mail" directly below the ancillary service endorsement.

e. Mail that can qualify for Shipper Paid Forwarding under the applicable standards in 2.3.5 is forwarded or returned at the First-Class Mail single-piece rate or Priority Mail single-piece rate applicable for the weight of the piece.

f. If a Standard Mail piece and any attachment to that piece are not opened by the addressee and the sender has guaranteed forwarding and return postage, the addressee may refuse delivery of the piece and have it returned to the sender without affixing postage. If a Standard Mail piece or any attachment to that piece is opened by the addressee, the addressee must affix the required postage to return the piece to the sender.

Standard Mail with Delivery Confirmation must be endorsed "Address Service Requested," "Forwarding Service Requested," "Return Service Requested," or "Change Service Requested."

h. When a large volume of identical-weight pieces originates from a single mailer and is endorsed "Return Service Requested," the USPS may weigh a sample of at least 25 pieces and divide that weight by the number of pieces to determine the weight of a single piece. After the per piece weight is determined, all the pieces are weighed in bulk and divided by the per piece weight to determine the total number of pieces. The return postage is calculated using these numbers. Pieces of identical weight counted in this manner are returned to the sender with the new address or the reason for nondelivery endorsed on the piece.

i. A weighted fee is charged when an unforwardable or undeliverable piece is returned to the sender and the piece is endorsed "Address Service Requested" or "Forwarding Service Requested." The weighted fee is the First-Class Mail or Priority Mail single-piece rate and, if applicable, the nonmachinable surcharge (see 123.1.0 or 133.1.0), multiplied by 2.472 and rounded up to the next whole cent (if the computation yields a fraction of a cent). The weighted fee is computed (and rounded if necessary) for each piece individually. Using "Address Service Requested" or "Forwarding Service Requested" obligates the sender to pay the weighted fee on all returned pieces.

j. A returned piece endorsed "Return Service Requested" is charged the single-piece First-Class Mail rate for the weight and shape of the piece, and the nonmachinable surcharge if applicable, or the Priority Mail rate for the weight and destination of the piece. The appropriate First-Class Mail rate for a Not Flat-Machinable piece is the First-Class Mail parcel rate.

k. Mail sent as Bulk Parcel Return Service (BPRS) under 11.0 is returned at the BPRS per piece fee if one of the endorsements includes "— BPRS" as shown in Exhibit 1.5.3k.

If a Package Services piece or any attachment to that piece is opened by the addressee, the addressee must affix the required postage to return the piece to the sender. If the addressee does not want to pay forwarding postage for all Package Services mail, the postmaster of the new address must use Form 3546 to notify the postmaster of the old address to discontinue the forwarding of Package Services mail.

e. Package Services mail bearing a postage meter indicia from a customer meter that is unaddressed and without a return address (undeliverable) is returned to the post office of mailing.
