Pricing
Flat pricing.
No per-lookup surcharges.
Start free with address validation, ZIP+4, and rate shopping. Upgrade when you need tracking, batch validation, intelligence, or BYOK.
Validation runs on a bring-your-own-key model — USPS requires every business to hold its own Addresses API license, and we build for that rule instead of around it. Flat pricing stays honest because you never pay us per lookup on someone else's license.

Address validation: flat rate vs per-lookup
Most address validation APIs charge per lookup. RevAddress charges a flat monthly fee — after that, every lookup is $0. At 4,300+ lookups/month, RevAddress is cheaper than every per-lookup competitor.
| Provider | 1K lookups | 10K lookups | 50K lookups | Batch? |
|---|---|---|---|---|
| Smarty | $40 | $400 | $2,000 | Per-lookup |
| Melissa | $30 | $30 | $150 | Per-credit |
| Google AV | $5 | $50 | $250 | Per-call |
| Lob | ~$20 | ~$200 | ~$1,000 | Per-lookup |
| RevAddress | $29 | $29 | $79 | 50/call |
RevAddress Starter ($29/mo) includes 5,000 lookups. Growth ($79/mo) adds batch validation — 50 addresses per call. Cached addresses are free. Learn about batch validation →
Shipping API: per-lookup fees vs flat rate
Most shipping APIs charge per lookup or per label. RevAddress is flat — tracking, intelligence, checkout validation, and BYOK included in your plan. BYOK DPV starts at Starter; Pro and Enterprise merchants create labels through their own USPS credentials.
| Platform | Monthly | Per lookup | 1K lookups/mo | BYOK |
|---|---|---|---|---|
| EasyPost | $0 | $0.08 | $80 | No |
| Shippo | $19 | $0.05 | $69 | No |
| USPS native | $0 | $0 | $0 | N/A |
| RevAddress | $79 | $0 | $79 | Pro+ |
USPS native is free but requires your own OAuth management, token refresh, and error handling. RevAddress handles USPS infrastructure — OAuth, caching, webhooks, SDKs — so you build, not plumb. Full comparison →

Common questions
What counts as a request?
Every API call to any endpoint counts as one request. Address validation, tracking lookups, intelligence queries — each is one request. Cached responses don't count.
What happens if I exceed my limit?
Requests over your plan limit return a 429 status code. No surprise charges. Upgrade from your dashboard or start a new checkout from pricing. Email [email protected] if you need help.
What is BYOK?
Bring Your Own Keys. Use your own USPS Developer Portal credentials with our infrastructure. Your credentials are AES-GCM encrypted at rest with per-merchant keys. Single-key BYOK DPV verification is included from Starter. If your USPS app has label creation access, Pro and Enterprise create shipping labels through your own credentials and payment authorization — we manage the token lifecycle, rate limits, and storage.
Can I try the API for free?
Yes. Get a free API key to validate addresses, extract addresses from unstructured text, resolve ZIP+4, and compare rates. Upgrade when you need tracking, intelligence, batch validation, or BYOK.
How does this compare to EasyPost?
Our Growth plan at $79/mo includes 25,000 requests with batch validation, address intelligence, and Checkout Guard — no per-lookup surcharges.
Can I cancel anytime?
Yes. No contracts, no cancellation fees. Cancel from your dashboard or email [email protected]. Your API key stays active until the end of the billing period.
Monthly vs annual billing?
Annual plans save 20% — pay for 10 months, get 12. Same features, same limits. Choose monthly or annual at checkout. Existing customers can switch from their dashboard or by emailing [email protected].
