Proposed Service Standards

The Postal Service is looking to move ahead with service standard changes to support Delivering for America network changes at a later date in 2025.  We intend to continue providing service standard data files for customer use to determine the number of days in transit. The technical documentation and sample data sets provided here will outline the future file layouts to assist customers in preparing their systems for these upcoming changes. We will issue another update once the final decision is made regarding the implementation of new service standards

Description

The Service Standard data will be made available to customers via downloadable files and API to incorporate it into their systems. To minimize customer impact, we will provide downloadable files in the same manner as today – base standards by 3-digit origin, 3-digit destination, product and service standards in number of days with a 5-digit by 5-digit supplemental file.  We will also provide new file formats, by product, that combine the base and supplemental standards data into a single file.  There will be 2 variations of this file format, a full 5-digit by 5-digit layout and a combined 3-digit and 5-digit layout.  For customers seeking real-time access to this information, we will also provide an API that will enable customers to query our system using a single 5-digit pair and product (or all products) and receive the number of day standard as a response.
