EasyPost is a multi-carrier rate shopping shipping solution. The EasyPost API is one integration point for 100+ carriers, including USPS eVS. All USPS eVS functionality and pricing are accessible using the EasyPost API. EasyPost standardizes the inconsistencies across carrier APIs with its RESTful interface.
The USPS eVS API is designed for very high-volume package mailers. e-VS, or Electronic Verification System, can be integrated directly through USPS, unlike most other USPS options which require a USPS Provider.
e-VS can be used for postage on Domestic packages and Standard Mail machinable mailings. It cannot be used for International shipments.
Since USPS e-VS is designed for very high volume mailers, the rates are on a contract basis. Rates and pricing for e-VS are typically under a Negotiated Service Agreement (NSA). These contracts are rates above USPS Commercial Base Pricing and USPS Commercial Plus Pricing.
If you think you are in range of a Negotiated Service Agreement or interested in exploring eVS, please click the button below and we'll contact you shortly.
