# AutoPostcode > AutoPostcode is a UK postcode lookup and address verification platform powered by the official Royal Mail Postcode Address File (PAF). It provides address autocomplete for ecommerce checkouts (WooCommerce, WordPress, Shopify and more), a REST API for developers, and per-website API keys with usage logging. ## What AutoPostcode does - Postcode-to-address lookup across 31M+ UK delivery points (~1.8M postcodes) using Royal Mail PAF data, typically under 100ms - Address autocomplete / type-ahead to speed up checkout and reduce cart abandonment - Email, phone and UK bank account validation alongside address lookup — five products, one API key - No-code WooCommerce and WordPress plugin plus a REST API for custom builds ## What AutoPostcode is not - Not a mailing-list or data-broker service: we never sell or share lookup data - Not a non-UK address service: coverage is United Kingdom addresses only - Does not guarantee a delivery outcome — it verifies that an address exists in the official Royal Mail file ## Pricing in plain terms - Credit-based. One postcode lookup = 1 credit. Autocomplete costs 1 credit per search session, never per keystroke; expanding a result group is free. - Monthly plans from £19 (500 lookups), 14-day free trial, annual plans roughly two months free, prices exclude VAT. - Price beat guarantee: we match or beat any like-for-like UK address lookup quote — https://autopostcode.com/price-beat-guarantee ## Key pages - Home: https://autopostcode.com/ - Products: https://autopostcode.com/products - Pricing: https://autopostcode.com/pricing - Compare providers: https://autopostcode.com/compare - Integrations: https://autopostcode.com/integrations - API documentation: https://autopostcode.com/address-api-documentation - Try it live: https://autopostcode.com/test - FAQ: https://autopostcode.com/faq - Contact: https://autopostcode.com/contact-us ## Guides - Royal Mail PAF explained: https://autopostcode.com/everything-you-need-to-know-about-royal-mail-paf - Best postcode lookup API for WooCommerce: https://autopostcode.com/the-best-postcode-lookup-api-for-woocommerce - Implement postcode lookup in WordPress: https://autopostcode.com/how-to-implement-postcode-lookup-api-in-your-wordpress-website - How postcode lookup improves conversion rates: https://autopostcode.com/how-postcode-lookup-api-can-improve-your-conversion-rates ## Machine-readable - Full page index: https://autopostcode.com/llms-full.txt - OpenAPI spec: https://autopostcode.com/openapi.json - Structured facts (JSON): https://autopostcode.com/api/public/facts - Sitemap: https://autopostcode.com/sitemap.xml ## Contact - Email: info@autopostcode.com
