EasyPost March 17 Deadline:
Your Migration Options Before Auto-Enrollment

What Happens on March 17

EasyPost's new pricing went live on February 23, 2026. The migration window closes on March 17. Here's what the auto-enrollment actually means for your account:

IF payment_method_on_file:
  auto_enroll → BYOCA plan
  ├ $20/month base fee
  ├ First 3,000 labels/month: free
  ├ Labels 3,001+: $0.08 each
  └ Billing starts immediately

ELSE:
  auto_enroll → Free Access
  ├ Address verification: ✓
  ├ Tracking: ✓
  ├ Label generation: ✗ disabled
  └ Rate shopping: ✗ disabled

The critical detail: this is not opt-in. EasyPost is choosing for you based on your payment method state. If you're generating labels through EasyPost today and haven't explicitly selected a plan, you need to make a decision before March 17 or let EasyPost make it.

• Per-label cost: Previously $0.05, now $0.08 (60% increase)
• Free tier: Dropped from 5,000 to 3,000 labels/month
• New BYOCA fee: $20/month to use your own carrier account (was free)
• Rate limits: Free Access accounts now get reduced API rate limits

Price Comparison: EasyPost vs RevAddress

Real numbers at four volume tiers. EasyPost costs assume BYOCA plan ($20/month base + $0.08/label above 3,000 free). RevAddress pricing is flat — no per-label fees, no overages, no surprises.

base_fee  = $20
free_tier = 3,000 labels
overage   = $0.08 per label above free tier

At 5,000 labels:
  $20 + (5,000 - 3,000) × $0.08 = $20 + $160 = $180/mo

At 10,000 labels:
  $20 + (10,000 - 3,000) × $0.08 = $20 + $560 = $580/mo

At 50,000 labels:
  $20 + (50,000 - 3,000) × $0.08 = $20 + $3,760 = $3,780/mo

The crossover is around 3,363 labels/month. Below that, EasyPost BYOCA is cheaper than RevAddress Starter ($29/mo). Above that, flat pricing wins — and the gap becomes a canyon at scale. At 50,000 labels/month, the difference is $3,281/month — that's $39,372/year back in your operating budget.

What You Lose with EasyPost's New Plans

The pricing increase isn't the full picture. EasyPost's plan restructuring also introduced restrictions that didn't exist before February 23:

Migration Code Comparison

The migration surface is smaller than you think. Here's what EasyPost code looks like versus RevAddress — same operations, side by side.

Address Validation

import easypost

client = easypost.EasyPostClient(
    "EASYPOST_API_KEY"
)

address = client.address.create(
    street1="1600 Pennsylvania Ave",
    city="Washington",
    state="DC",
    zip="20500",
    country="US",
    verify=["delivery"],
)

# Check verification
if address.verifications.delivery.success:
    print(address.street1)
    print(address.zip)

from usps_v3 import USPSClient

client = USPSClient(
    api_key="REVADDRESS_API_KEY"
)

result = client.addresses.validate(
    street_address="1600 Pennsylvania Ave",
    city="Washington",
    state="DC",
    zip_code="20500",
)

# DPV-confirmed result
print(result.address.street_address)
print(result.address.zip_code)

Label Creation

import EasyPostClient from '@easypost/api';

const client = new EasyPostClient(
  "EASYPOST_API_KEY"
);

const shipment = await client.Shipment.create({
  from_address: { street1: "388 Market St",
    city: "San Francisco", state: "CA",
    zip: "94105" },
  to_address: { street1: "1600 Pennsylvania Ave",
    city: "Washington", state: "DC",
    zip: "20500" },
  parcel: { weight: 16, length: 10,
    width: 8, height: 4 },
});

const bought = await client.Shipment.buy(
  shipment.id,
  shipment.lowestRate()
);

console.log(bought.postage_label.label_url);
console.log(bought.tracking_code);

import { USPSClient } from 'usps-v3';

const client = new USPSClient({
  apiKey: "REVADDRESS_API_KEY"
});

// Get rate
const rate = await client.prices.rate({
  originZip: "94105",
  destinationZip: "20500",
  weight: 16,
  mailClass: "PRIORITY_MAIL",
  processingCategory: "MACHINABLE",
});

// Create label
const label = await client.labels.create({
  fromAddress: { streetAddress: "388 Market St",
    city: "San Francisco", state: "CA",
    zipCode: "94105" },
  toAddress: { streetAddress: "1600 Pennsylvania Ave",
    city: "Washington", state: "DC",
    zipCode: "20500" },
  weight: 16,
  mailClass: "PRIORITY_MAIL",
});

console.log(label.labelUrl);
console.log(label.trackingNumber);

BYOK: Something No Competitor Offers

Bring Your Own Keys (BYOK) means you use your own USPS credentials through RevAddress. Your USPS Web Tools account, your Client ID and Secret, your rate limits. RevAddress acts as infrastructure — not a middleman that holds your carrier relationship hostage.

POST https://api.revaddress.com/v1/byok/credentials
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json

{
  "client_id": "your-usps-client-id",
  "client_secret": "your-usps-client-secret"
}

→ 201 Created
{
  "status": "active",
  "encrypted": true,
  "isolation": "durable_object"
}

After setup, all your API calls automatically route through your own USPS credentials. No code changes needed — same endpoints, same SDKs, same response format. Just your credentials instead of shared ones.
