Address Resolution

Address resolution is the process of matching a freeform UK address string to its official Unique Property Reference Number (UPRN), enabling you to link disparate data sources and access our full property data.

Our AI-powered resolver achieves 99.7% accuracy on standard addresses. Each response includes a confidence score (0-100) so you can set thresholds for automated vs manual review.

We handle virtually any UK address format including abbreviated street types, missing postcodes, flat/unit variations, and common misspellings. Our AI model was trained on millions of real-world address variations.

Average response time is ~38ms. The API supports batch processing for high-volume address matching, with concurrent request limits based on your subscription tier.
