Send the Address
POST the raw address - street, city, postal code, country. We accept partial, messy, or user-typed input.
We Validate & Normalize
The address is checked against authoritative postal databases, corrected, normalized to local format, and enriched with region data.
Get a Confidence Score
Receive a validated address with a confidence score, any suggested corrections, and a clear valid/invalid flag.
Clean Addresses Mean Successful Deliveries
Every failed delivery starts with a bad address. Fix them before they ship.
Checkout Validation
Validate addresses in real-time as customers type. Catch errors before the order is placed, not after delivery fails.
Address Autocomplete
Speed up checkout with smart suggestions as customers type. Fewer keystrokes, fewer errors, faster conversions.
Database Cleanup
Run your entire customer address database through validation. Fix formatting issues, update postal codes, and flag undeliverable addresses.
Cross-Border Compliance
Normalize addresses to meet local postal standards in each European country. Proper formatting for DE, PL, CZ, and more.
