Launch an Address and Identity Verification API

The big verification providers price and design for enterprises, leaving underserved corners: one country's quirky address formats, rural and non-standard addresses, or verification tuned to one industry's records; verification calls sit inside signup and checkout flows, which makes the revenue extremely sticky once integrated.

1. 1

   Pick your verification corner

   Full global address verification is an enterprise-scale fight. One country done excellently, hard address types (rural routes, new construction, multi-unit), or business-identity checks for one industry are corners a small team can own.

2. 2

   Secure the reference data legitimately

   Address verification runs on authoritative sources: postal service datasets, national address registries, and licensed geocoding data, each with licensing terms and fees. Personal identity verification adds heavy regulatory weight; business and address verification is the saner solo start.

3. 3

   Validate with five integration conversations

   Talk to teams at e-commerce shops, delivery startups, and vertical SaaS in your target corner. Ask their bad-address costs (failed deliveries, chargebacks, support tickets) and what accuracy would be worth per thousand lookups.

4. 4

   Build for the accuracy edge cases

   Standardization, validation against reference data, geocoding, and confidence scores, with AI-assisted matching for the messy inputs rule-based systems reject. Publish honest accuracy benchmarks on the hard cases; that is your entire pitch against the giants.

5. 5

   Price per lookup with a free tier

   Verification commonly bills per lookup (fractions of a cent to a few cents) with monthly minimums, plus a free developer tier for integration testing. Excellent docs and drop-in code samples decide these evaluations.

6. 6

   Commit to production-grade reliability

   Your API sits inside signup and checkout flows, so latency and uptime targets, a status page, and versioning discipline are contractual from customer one. Expect the first ten customers to take months; integrated verification then renews for years.
