USPS eVS Pre-certified Vendor

ELEXtensions is now recognized as a USPS eVS Electronic Verification System Pre-certified Vendor.

IMPORTANT NOTE: The Print Label functionality of this plugin works only for USPS eVS Accounts, as USPS doesn’t provide a direct API to integrate it for non-eVS USPS Accounts. To print the USPS Shipping Labels for the regular USPS accounts, please check out our Stamps USPS Plugin.

Note that Shipment Tracking and Realtime Rates functionality don’t have eVS account dependency and work fine with any USPS accounts. We are committed to continuously improving the plugin by updating the plugin with the latest changes in the USPS Rates as fast as possible.

Print Shipping Label

Print Shipping Label (USPS eVS – With Postage)

If you are USPS e-VS customer, print shipping labels with Postage (using USPS eVS APIs) from within WooCommerce. 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.
In addition to this, you can even create eVS shipments in bulk, in the WooCommerce Orders page.If you don’t have USPS eVS Account, then we recommend using ELEX Stamps.com USPS Plugin for printing USPS Labels. After the purchase, if you want to switch to the ELEX Stamps.com USPS plugin, you can do it free of any additional cost by contacting our support team.

Add the Importer Tax Registration Details for Barrier Free Shipments

Enter your shipper tax registration details to create shipments to any country barrier-free for your customers. These details will be added to the shipping labels, which makes the customs process easier.

    This plugin is working great, a few snags at the beginning but the author was quick to help and fix the issues. Due to changes in the USPS and its rules for API/volume. I do not do a crazy high volume of mailing so when the change happened I didn’t realize it rendered my plugin useless. But never fear Lorenzo helped fix this up quickly and professionally!

    I’ve had this plugin for around 6 months and I absolutely love it. The support is way above average…it’s stellar. Lorenzo answers all of my questions by the following morning (we are in different time zones). This USPS plugin really does work as well as it says. So so so much better than the free one in Woocommerce.

    Very happy with the flexibility of the plug-in, and their support is really great. I’m new to wooCommerce and WordPress in general. They did a great job of responding to my questions and going the extra mile to consult with the development team for some of my questions.

    Plugin itself is very functional, easy to use and configure. I want to underline the exceptional support the company provides. They pay detail attention to the subject, even it needs communicating with third-party service providers. I’m a happy user of other products of this company and I would recommend ELEX plugins to everybody interested in upgrading e-commerce functionality and adding valuable features to online stores.
