Why Developers Switch to FastAddress UK
1. Elimination of Checkout Lag
Every keystroke in an address field makes an API call. At 85ms+ latency, users experience visible input stutter. FastAddress returns results in under 15ms, creating a smooth native checkout experience.
2. Zero-Cost OS UPRN Identifiers
Unique Property Reference Numbers (UPRNs) are vital for EPC matching, Land Registry queries, and local government compliance. We bundle UPRNs on all 21.1M records at no extra charge.
3. 10-Minute Migration
Swapping to FastAddress is a matter of changing your fetch URL. Our JSON response cleanly returns address_string, postcode, uprn, and coordinates.
