About

Postcoder is an API from Allies Computing that gives developers a single endpoint for verifying and validating customer contact data at the point of entry. Used across sectors from healthcare to retail, it's built to drop into checkout, onboarding, and account creation flows with minimal friction. What's included: Address lookup – Postcode, partial address, or coordinate-based search across Royal Mail PAF, Ordnance Survey AddressBase, and 249 countries worldwide. Bank validation – Real-time sort code and account number verification, with branch data and direct debit eligibility returned in the response. Email validation – Domain and formatting checks with disposable address detection. Mobile validation – Live network status checks across 200+ countries. OTP verification – SMS-based one-time password delivery. Clear documentation, multi-language sample code, and a straightforward REST structure mean integration is quick. 30 day free trial with no credit card required.

About

Prompt customers to rectify and address issues before the order gets shipped out. An address validator is a simple and effective solution to crush address problems. Festive decorations can put your customers in the right mood for shopping. Add prompts to suggest corrections and to alert customers when addresses cannot be verified. Tailor the app to match your needs, you have full control over the colors, messaging, and functionality. Prevent inaccurate addresses that result in returned shipments & costly redelivery fees. We did the heavy lifting so you can get started in seconds without coding. Customers often mistype shipping addresses and this leads to failed deliveries and ultimately, upset customers. The address validator is fully optimized for mobile, tablet, and desktop devices. The first 100 orders are free. No credit card is required to get started. Simple installation without coding and the first 100 orders are free.
