# Onwan > Onwan is the Saudi Arabia address validation app for Shopify. It collects, verifies, and manages Saudi National Addresses at checkout with real-time API validation. Supports 5 capture methods, bilingual EN/AR, and automated emails. Required for compliant delivery to KSA. Onwan helps Shopify merchants shipping to Saudi Arabia comply with National Address requirements. The Saudi National Address uses a short code format (e.g., RAGI2929) that maps to precise locations. Carriers like Aramex, SMSA, and DHL require validated addresses for successful delivery. Without validation, shipments are delayed, returned, or lost. ## Product - [Onwan – Saudi Arabia Address Validator](https://onwan.app): Main product page with features, pricing, and install link - [Install from Shopify App Store](https://apps.shopify.com/national-address): Direct link to install Onwan on Shopify ## Blog & Guides - [Blog index](https://onwan.app/blog): All articles on Saudi address validation and Shopify - [What is the Saudi National Address and Why Shopify Merchants Need It](https://onwan.app/blog/saudi-national-address-shopify): Complete guide to the Saudi National Address system - [How to Collect Saudi National Addresses at Shopify Checkout](https://onwan.app/blog/collect-saudi-addresses-checkout): Step-by-step capture methods and setup - [Saudi Arabia E-commerce Delivery: Address Validation Requirements](https://onwan.app/blog/saudi-ecommerce-delivery-validation): KSA carrier requirements and compliance - [RAGI Short Address Format Explained for E-commerce](https://onwan.app/blog/ragi-short-address-explained): Understanding the RAGI format and validation - [Reducing Failed Deliveries in Saudi Arabia: A Shopify Guide](https://onwan.app/blog/reducing-failed-deliveries-saudi): How validated addresses reduce failed deliveries ## Contact - Website: https://onwan.app - Shopify App Store: https://apps.shopify.com/national-address ## AI Discovery Files - [Sitemap](https://onwan.app/sitemap.xml): XML sitemap of indexable pages - [Robots](https://onwan.app/robots.txt): Crawler access rules
