Address autocomplete suggests verified addresses as the user types. For UK sites the differentiators are data accuracy, how easily it drops into your checkout, and the pricing model.
| What to look for | Why it matters |
|---|---|
| PAF-backed data | Suggestions are real, deliverable UK addresses |
| No-code plugin | Go live without engineering on WooCommerce/WordPress |
| Mobile performance | Most cart abandonment happens on mobile |
| Transparent pricing | Costs stay predictable as orders grow |
