One of the top USPS shipping solutions for WooCommerce is the USPS Shipping Method extension, which connects your store to the USPS API to show real‑time domestic and international rates at checkout. It supports services like Priority Mail, First Class, and Express, helping customers see accurate costs based on weight and destination. Another strong option is ELEX EasyPost or USPS Live Rates plugins that fetch live USPS rates and can include label printing and tracking features. Alternatively, WooCommerce Shipping Services integrates USPS rates along with other carriers for automated label printing and streamlined fulfillment.
