EasyPost vs RevAddress:
USPS Shipping API Pricing Compared

What Changed at EasyPost

On February 23, 2026, EasyPost updated their pricing for the USPS integration:

• Per-label cost: $0.05 → $0.08/label (60% increase)
• Free tier: 5,000 → 3,000 labels/month
• New BYOCA fee: $20/month to use your own carrier account

For teams under 3,000 labels/month, EasyPost is still free. For everyone else, the math changed significantly.

The Pricing Math

Apples-to-apples comparison at different volume tiers. EasyPost costs assume USPS-only usage (their most common case). RevAddress pricing is flat — no per-label fees.

First 3,000 labels/month:  Free
Labels 3,001+:             $0.08 each

Example — 5,000 labels:
  3,000 free + 2,000 × $0.08 = $160/month

Example — 25,000 labels:
  3,000 free + 22,000 × $0.08 = $1,760/month

Breakeven vs RevAddress Starter ($29/mo):
  $29 / $0.08 = 362.5 labels above free tier
  3,000 + 363 = ~3,363 labels/month

The breakeven is ~3,363 labels/month. Below that, EasyPost's free tier wins. Above that, flat pricing pulls ahead — and the gap widens fast.

Feature Comparison

Pricing isn't everything. Here's how the platforms compare on features that matter to developers:

When EasyPost Still Wins

EasyPost is the right choice if:

• 1. You need multi-carrier support. EasyPost connects to 100+ carriers — UPS, FedEx, DHL, and dozens of regional carriers. RevAddress is USPS-only. If you ship via multiple carriers through a single API, EasyPost has no real alternative at its price point.
• 2. You're under 3,000 labels/month. Free is free. If your volume sits comfortably under the free tier, there's no pricing argument to make.
• 3. You need enterprise carrier relationships. EasyPost has negotiated rates with major carriers. If you're leveraging those pre-negotiated rates, the per-label fee may be offset by shipping discounts.
• 4. You need insurance and refund management. EasyPost's built-in shipping insurance and automated refund workflows are mature features that USPS-only platforms don't replicate.

When RevAddress Wins

RevAddress is the better fit if:

• You only ship USPS. No point paying a multi-carrier abstraction tax for a carrier you don't use. RevAddress is a direct USPS v3 API — no middleware, no markup on postage.
• You want predictable billing. Flat pricing means your API cost doesn't scale with your label volume. At 10,000 labels/month, you're paying $79 — not $560.
• You want BYOK without a surcharge. Bring Your Own Keys is included at no extra cost. Your USPS credentials, your rate limits, your data. No $20/month fee to use your own account.
• Rate limits are killing you. Direct USPS access caps at 60 req/hr. RevAddress handles rate limiting, caching, token management, and automatic retries at the edge.
• You want open-source SDKs for USPS v3. Official Python and Node.js SDKs with full TypeScript types, automatic OAuth token management, and zero dependencies (Node) / one dependency (Python).

The BYOCA Factor

EasyPost's new $20/month BYOCA (Bring Your Own Carrier Account) fee deserves its own callout. Previously free, this now adds a fixed cost on top of per-label pricing for anyone using their own USPS credentials through EasyPost.

Why BYOK/BYOCA matters:

• Rate limit isolation — Your credentials = your rate limit pool. Not shared with other tenants.
• Data ownership — Your shipping data goes through your USPS account, not a shared API key.
• Portability — If you leave the platform, your USPS relationship stays intact.

RevAddress includes BYOK at every tier. No extra fee. Your credentials are AES-GCM encrypted at rest and never logged in plaintext.

Switching Is Straightforward

If you're coming from EasyPost's USPS endpoints, the migration surface is small. EasyPost wraps USPS behind their own API schema. RevAddress is closer to the raw USPS v3 API, which means:

• 1. Address validation — same inputs (street, city, state, zip), JSON response with DPV codes.
• 2. Label creation — POST with shipper/recipient/package details, get back a label URL and tracking number.
• 3. Tracking — GET with tracking ID, structured JSON response with scan events.

The SDKs handle OAuth token management automatically. Most migrations are a weekend project — swap the client library, update the response parsing, done.
