USPS

Overview

ShipScience downloads USPS invoice files daily from your PC Postage provider (the service you use to purchase USPS labels). Claims are filed directly with USPS through a separate usps.com account.

Setup requires two things:

• Invoice ingestion — credentials for your PC Postage provider so ShipScience can pull daily invoice data.
• Claims filing — a usps.com login configured for your business so ShipScience can file claims, upload evidence, and track claim status.

Invoice Ingestion

Provide credentials for the PC Postage provider you use to buy USPS labels. The required credentials depend on your provider:

Enter these credentials in the ShipScience portal under Data Sources.

*Note that currently USPS Ship reporting does not provide recipient name and address information required to file claims, additional manifest integration is required to submit claims for those shipments.

Tracking

ShipScience currently retrieves tracking updates directly from USPS.

⚠️

In April 2026, USPS will discontinue this direct tracking service. After that date, client-specific tracking will need to be configured.

For USPS customers with their own MID, ShipScience has partnered with USPS and has an approved "app" to fetch tracking data on your behalf. Please contact [email protected] to request setup, this requires an IP Agreement submitted by ShipScience to setup.

For EasyPost customers, we obtain tracking information directly from EasyPost.

For customers buying labels from Endicia/Stamps or on other MIDs not owned by the shipper, please contract [email protected] to explore next steps.

Claims Filing

USPS claims are filed directly through usps.com — not through your PC Postage provider. ShipScience requires a dedicated usps.com login for your business with permissions to:

• File new claims
• Upload supporting evidence
• Track claim status

Provide these usps.com credentials separately from your invoice ingestion credentials above.
