USPS Ground Advantage

Outcome​

You will learn how to recognize USPS Ground Advantage among the Rates returned for a Shipment, and how to carry that returned Rate through the standard Label workflow.

Ground Advantage adds no public endpoint, request field, or response field. The mechanics are the carrier-generic ones described in USPS with Mailhub.

When to use this guide​

Use this guide when a returned Mailhub Rate identifies USPS Ground Advantage.

This page is context for a Rate you already have, not advice about which service to ship with. Mailhub publishes no recommendation, and a returned Rate is the only evidence of what a Shipment can use.

If you are still assembling the Rates request itself, start from Get Shipping Rates.

Identify the returned service​

Ground Advantage is returned as the exact normalized value:

"serviceName": "USPS Ground Advantage"

Compare the returned carrier and serviceName values instead of assuming which service came back, and read serviceCode from the response instead of hard-coding one. See Identify a returned USPS service for the full recognition example and the other known service names.

Buy and manage the Label​

Retain the returned Rate id, then follow the canonical guides — they remain the complete reference for each request and response, and this page does not restate them:

Mailhub publishes its own platform requirements for a Shipment — see Requirements & Restrictions. USPS may apply additional service-specific eligibility or restrictions that Mailhub does not publish.
