Section divider line

Optional information lines include the optional endorsement line (OEL), carrier route information line, ACS participant code, and mailer’s keyline. The OEL and the carrier route information line may be printed on the mailpiece or label when the address is printed. A mailer’s keyline is reserved for the mailer’s use except where required by the USPS.

Optional Endorsement Line (708.7.0)

Section divider line

Mailers may prepare mailings without applying pressure-sensitive labels to the top mailpiece of bundles by using a specific OEL above the address block or on the address label on the top mailpiece of a bundle.

Type and style:

ZIP Code: Except for carrier route bundles, the OEL must include the appropriate ZIP Code information (see 708.7.2.5).

Address Change Service (507.4.2)

Section divider line

Mailers receiving address corrections through Address Change Service (ACS) may use the first eight positions on the left side of the OEL for the ACS participant code. ACS codes must be printed in a non-narrow variant of Helvetica or Arial sans serif fonts in a range of 10 to 12 points (see Publication 8A, Address Change Service - Traditional, or Publication 8B, One Code ACS Technical Guide for details).

Carrier Route Information (708.8.0)

Section divider line

Bundles made up to individual carrier routes, rural routes, highway contract routes, Post Office box sections, or general delivery units may be prepared without a facing slip if the standards in 708.8.1 are met. These standards apply to carrier route Periodicals, Enhanced Carrier Route Standard Mail, and carrier route Bound Printed Matter mailings. For preparation of facing slips, see 601.2.14.

Placement and format:

Carrier route information consisting of a descriptive prefix (or its abbreviation), plus a route number or numeric code, must be on the top line of the address, either alone or with other optional information. A minimum of 10 spaces must be allowed for carrier route information when included with other information on the OEL. Carrier route information must be preceded by at least two asterisks (**). The carrier route information is in addition to the marking standards for the class of mail and price claimed.


Carrier Route C

General Delivery Unit G

Highway Contract Route H

Post Office Box Section B

Rural Route R


Section divider line

A mailer’s internal keyline or comparable information may not be placed above or on the same line as the OEL. Authorized Manifest Mailing System mailers must use a keyline as described in 705.2.3.
