EasyPost vs RevAddress: USPS Shipping API Pricing Compared

EasyPost and RevAddress are not the same shape of product, and the pricing comparison only makes sense once that is on the table. EasyPost is a multi-carrier abstraction: one API, over 100 carriers, per-label economics. RevAddress is a USPS-only layer with a flat monthly fee, where the postal relationship stays in your name.

This post has the current published figures for both, the volume where the crossover sits, and the parts of each bill that a side-by-side table hides.

What EasyPost publishes today

Read off the EasyPost pricing page on August 23, 2026:

One thing to notice before the math: the per-label fee is not a published number. The page says a per-label fee applies above the free tier and does not say what it is. You get it from your account or from sales.

That matters because the widely circulated figure comes from EasyPost’s February 23, 2026 pricing change, which set the per-label rate at $0.08, cut the free tier from 5,000 labels to 3,000, and introduced the $20/month BYOCA fee. Every dollar figure in the next section is computed at that announced $0.08 rate. It was accurate when announced and it is no longer something you can verify on the page, so treat it as an estimate and confirm your own rate before budgeting.

The label math, at the announced rate

At $0.08 per label above 3,000 free:

BYOCA has no free allowance: every label carries the fee, plus $20 a month.

Three thousand labels a month covers a lot of small operations, and at that volume nothing in this post argues against EasyPost.

RevAddress Pro on your own USPS license

The earlier version of this comparison got this part wrong.

Label creation on RevAddress runs on your own USPS license, at the Pro tier, $199 a month with access by request, which covers 100,000 requests/mo. Label voids are on the same tier and the same license. RevAddress does not create labels on its own credentials, because postage has to be paid by the entity that owes it: your Enterprise Payment Account pays USPS directly, exactly as it would if you called USPS yourself.

So at label volume the comparison is the Pro tier against per-label fees, rather than “$0.08 a label versus $79 a month”:

Postage is not a differentiator. You pay USPS either way, and neither platform marks it up. What differs is the platform fee on top. Against Free Access the crossover sits near 5,490 labels a month: the first 3,000 are free, and $199 buys about 2,490 more at $0.08. Against BYOCA, which has no free allowance, it sits near 2,240. Below those lines EasyPost is cheaper. Above them the flat fee stops moving and the per-label line does not.

BYOCA and your own USPS credentials

The BYOCA fee is the part worth reading twice, because it inverts the usual incentive.

Bringing your own carrier account normally saves a platform money: they stop fronting the carrier relationship. On EasyPost it costs you $20/month on top of per-label fees. If you already have a USPS account with negotiated terms, you pay for the privilege of using it.

Three reasons teams want their own credentials anyway:

• Rate-limit isolation. Your credentials draw on your own USPS rate-limit pool, not one shared with other tenants. If USPS grants you an increase, it applies to you in full.
• The relationship is yours. Volume, reporting, compliance posture and the line to USPS support stay in your name. A platform key gives you none of that.
• Portability. Leave the platform and the USPS relationship survives the move. That is the difference between switching vendors and re-onboarding with the Postal Service.

On RevAddress, bringing your own credentials is the model rather than an add-on, and there is no surcharge for it. Credentials are AES-GCM encrypted at rest with per-merchant keys.

What each platform is for

Read that table as two different jobs rather than a scoreboard. EasyPost sells breadth and takes a cut per shipment for it. RevAddress sells a flat, USPS-native layer and takes nothing per shipment, and it cannot ship your UPS packages.

Choose EasyPost if

1. You ship on more than one carrier. Over 100 carriers behind one API is the product, and there is no USPS-only answer to it at any price.
2. You are under 3,000 labels a month. The free tier costs nothing, and the pricing argument does not start until you cross it.
3. You want insurance and claims handled. EasyPost’s insurance at 1% of shipment value with automated claims is a mature feature that a USPS-only layer does not replicate.
4. Pre-negotiated carrier rates matter more than the platform fee. If EasyPost’s rates are lower than what you can get directly, the per-label fee can pay for itself.

Choose RevAddress if

1. USPS is the whole shipping stack. There is no reason to pay for a multi-carrier abstraction to reach one carrier.
2. You want the bill to stop moving. Above roughly 5,490 labels a month (2,240 against BYOCA) the flat fee is lower, and it stays lower as you grow rather than tracking volume.
3. You want your own USPS credentials without a surcharge. Rate limits, reporting and the USPS relationship stay yours, with no $20/month to use the account you already have.
4. You are hitting the 60-requests-per-hour wall. Calling USPS yourself caps there, shared across every endpoint your app touches. The managed layer handles caching, token refresh, retries and rate-limit smoothing, which the rate-limit guide covers in full.

Switching the USPS half

If you are moving USPS off EasyPost while keeping it for other carriers, the surface is small. EasyPost wraps USPS in its own schema; RevAddress sits closer to the raw USPS v3 shapes, so you are mostly renaming fields.

curl -X POST "https://api.revaddress.com/api/address/validate" \
-H "X-API-Key: rv_live_your_key" \
-H "Content-Type: application/json" \
-d '{
  "streetAddress": "1600 Pennsylvania Ave NW",
  "city": "Washington",
  "state": "DC",
  "ZIPCode": "20500"
}'

Field aliases are normalized, so street_address, address1, line1, zip and zip_code all resolve rather than returning a 400. Three notes on the rest:

• Labels. POST shipper, recipient and package details; you get a tracking number and a label URL back. This runs on your USPS license and needs CRID, MID and EPA enrollment first, which the CRID and MID guide walks through.
• Tracking. A GET with the tracking number returns structured JSON with scan events.
• The SDKs handle OAuth. pip install usps-v3 or npm install usps-v3, both MIT licensed. Tokens are fetched, cached and refreshed before expiry without you touching one.

One currency note that applies to both platforms: since August 1, 2026 the USPS Addresses API requires a signed license agreement and bills address lookups on a consumption curve. That is a USPS change, not a vendor change, and it lands on whoever holds the license. The USPS pricing guide covers the fee curve and the licensing sequence.
