What EasyPost's new 3% fee means for your USPS shipping costs

EasyPost recently announced a 3% fee on all USPS spend for customers on their PC Postage API, effective June 1, 2026. (It's the second pricing change EasyPost has made in 2026. In February, they raised per-label costs by 60%, cut the free tier, and introduced new mandatory fees.) If you're on EasyPost PC Postage, here’s what that means for you.

What's happening

USPS retired its old Web Tools API platform in January 2026 and required everyone to migrate to USPS Ship (v3). EasyPost offers two integration paths for USPS: PC Postage, which uses EasyPost's own wallet and managed billing, and USPS Ship, which lets customers bring their own USPS credentials and work with USPS directly. Starting June 1, EasyPost is charging customers 3% on all USPS spend to keep supporting the PC Postage path.

A better solution: use Shippo

Enjoy a managed experience on the USPS Ship API, without the operational overhead of going direct. Join over 4.6 million customers, including enterprise platforms, relying on our integration, and the track record to back it up: 100% label uptime throughout BFCM 2025. With Shippo, you also get:

• Fallback reliability. When USPS has a maintenance window or outage, we automatically switch to local label generation and manifesting. In 2025 alone, Shippo managed through 8 USPS outages this way, with 2 more in early 2026. Our local system runs at sub-100ms vs. USPS's 200ms. The switch is invisible.
• Billing management. We handle all billing with USPS on your behalf, including postage purchasing, account statements, full reconciliation against your actual daily volume. No prepaid float required.
• Rate accuracy. We apply USPS General Rate Increases and carrier updates to your rate cards automatically.
• Adjustments and refunds. We manage claims with USPS and pass them through at 0% fee.

The EasyPost alternative worth switching to

If EasyPost's pricing change has you looking at alternatives, most teams switch to Shippo in weeks, not months, without disrupting live operations.
