Express Mail packaging provided by the USPS must be used only for Express Mail. Regardless of how the packaging is reconfigured or how markings may be obliterated, any matter mailed in USPS-provided Express Mail packaging is charged the appropriate Express Mail price.
For each Express Mail item, the mailer must complete a mailing label - either Label 11-A or Label 11-E for Hold for Pickup service, or Label 11-B or Label 11-F for Post Office to Addressee Service. Mailers authorized to present Next Day or Second Day Express Mail items using an Express Mail Manifesting System are required to follow label preparation procedures in Publication 97, Express Mail Manifesting Technical Guide.
A mailer sending an Express Mail item may instruct the USPS to deliver an Express Mail Next Day Delivery or Express Mail Second Day Delivery item without obtaining the signature of the addressee or the addressee's agent, if not available, by signing a waiver on Label 11-B or Label 11-F. Completion of the waiver authorizes the delivery employee to sign for the delivery of the item. The item must be left in a secure location. Customers who waive the signature requirement will be provided only the delivery date and not an image of the signature when accessing delivery information on the Internet or when calling the toll-free number.
For Express Mail Next Day Delivery, the mailer must determine whether the item is destined to a 3-digit ZIP Code area to which Express Mail Next Day Delivery is offered from the point of origin. An Express Mail Next Day Delivery directory, showing detailed local information about Express Mail Next Day Delivery, is available at post offices. If the destination is not listed, the mailer must use Express Mail Second Day Delivery.
Except under 416, Enter and Deposit, all Express Mail Custom Designed items must be presented in sealed Express Mail pouches.
f. For Express Mail Manifesting, a special manifest is used to present Express Mail items for acceptance as described in Publication 97, Express Mail Manifesting Technical Guide. Form 3877, Firm Mailing Book for Accountable Mail, may be used only to list items for which extra services have been requested. See 705.2.6, Express Mail Manifesting Agreements, for information.
