Why developers switch from PostGrid
Validation-only platform
PostGrid is a standalone address validation API. RevAddress bundles validation with rate shopping, tracking, service standards, and label creation — one integration for the full shipping workflow.
Per-lookup pricing model
PostGrid charges per lookup across every tier. At 10K lookups/month: PostGrid costs $40. RevAddress Growth at $79/mo includes 25,000 requests — validation plus everything else.
No USPS shipping features
PostGrid can't help you ship a package. No rate shopping, no tracking, no labels. If you need more than validation, you need a second API. RevAddress covers the full USPS workflow.
Replace PostGrid and your shipping API with one integration
Validation, tracking, rates, and labels — one API key, one bill. Free tier included, no credit card.
