If the term “integrated network” seems ambiguous and confusing, that’s because it is.
The nonpartisan Congressional Research Service (CRS) analysis of the bill, states that the integrated network provision is “not defined in the bill, nor is it defined in USPS guidance.” CRS offers that the provision may refer to the delivery of packages and mail in the same vehicle, and even then, still urges Congress to “seek clarity” about the exact meaning.
The “integrated network” provision would essentially grant the USPS permission to continue bundling the expenses and earnings of its package business alongside its legal monopoly over sending letter mail. That would appear primarily to serve to hide advantages for large e-commerce giants while saddling consumers with the extra cost.
