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:

Provider	Credentials Needed
EasyPost	Account API credentials
Endicia / Stamps.com	Login + password
Pitney Bowes	Login + password
USPS Direct / USPS Ship	Login + password

Enter these credentials in the ShipScience portal under Data Sources.

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. ShipScience will reach out with setup instructions before the change takes effect.

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.
