Priority Mail Open and Distribute (PMOD) Service Updates: SCF Elimination

June 25, 2025

Priority Mail Open and Distribute (PMOD) service is a premium service provided primarily to large mailers and consolidators. Mailers prepare the mailings under standards for the class of mail and then enclose the mail in containers mailed at Priority Mail rates.

Mailings are prepared either as a pallet or sack (3-digit or 5-digit based on destination).Currently, customers creating Pallet PMOD shipments are required to include a 99M placard in addition to the pallet PMOD shipping label. Beginning July 13, 2025, the service will be updated to remove the requirement for two separate labels.

To streamline the scanning process and continue with the organization’s product modernization efforts, USPS will now only require the use of the current PMOD label on all Pallet PMOD shipments.In addition, the sack preparation of the PMOD/PMEOD service will also be updated to eliminate 3-digit sack preparations. Currently, when open and distribute sacks are tendered, they can be prepared as 3-digit sacks destined to a Mail Processing facility or 5-digit sacks destined to a Destinating Delivery Unit (DDU). Beginning July 13, 2025, USPS will require all customers shipping PMOD/PMEOD sacks to prepare them as 5-digit destined to a DDU.

Sacks will still be allowed travel through mail processing facilities (enroute) but will not be opened and processed until they reach the 5-digit destination.

Additionally, current language/requirements allow for mailable hazardous materials (HAZMAT) to be shipped in packages contained within PMOD and PMEOD. As part of this updated process, sacks will no longer be allowed to contain HAZMAT materials.
