Address Verification in 200 Countries: A Practical Playbook
Address verification breaks at borders. Here's a playbook that works in 200 countries without losing your conversion rate.
Address verification is the most jurisdiction-specific part of KYC. A flow that works in the US fails in Japan; a flow that works in Germany frustrates users in Nigeria. A globally usable program needs both layered automation and a deep library of fallback paths.
This playbook covers what works in each region, the data sources to use, and how to keep conversion high while remaining compliant.
Authoritative Postal Databases
USPS (US), Royal Mail PAF (UK), La Poste (France), Deutsche Post (Germany), Australia Post AMAS, Japan Post and dozens of national equivalents provide structured, validated address data. Use them to normalize and validate user input.
Government Residence Registries
Many countries operate residence registries: BRP (Netherlands), Folkbokföring (Sweden), Meldebescheinigung (Germany), juminhyo (Japan). Where lawful, an extract from these is the highest-assurance proof of address available.
Utility and Financial Statement Documents
Standard fallback. Accept electricity, water, gas, internet, mobile, bank and credit-card statements dated within 90 days. Use OCR + tamper detection + issuer cross-check.
Bank-Account Verification (Open Banking)
Plaid (US), TrueLayer (EU/UK), Stitch (Africa), Brankas (SEA) return a verified address direct from the bank record. Highest conversion rate, lowest fraud rate.
Emerging-Market Adaptations
In countries where utilities aren't in the customer's name, accept landlord letters with supporting ID, mobile-money statements where lawful, or remittance receipts. Document your acceptance matrix.
Geolocation as Corroboration
IP and device-location signals can corroborate (not replace) a claimed country. Treat mismatches as risk signals, not as failures.
Key Takeaways
- Use authoritative postal databases to normalize and validate input.
- Open-banking verification is the highest-converting PoA in supported markets.
- Document an emerging-market acceptance matrix.
- Treat geolocation as corroboration, not as primary evidence.
