Postcoder – Customer Data Verification Made Simple. Trusted by NHS, Sky, KFC, Rightmove, and over 10,000 organisations globally, Postcoder is the all-in-one API platform from Allies Computing that helps businesses collect accurate, verified customer data from the very first interaction. Rated 4.6 stars on G2 and the winner of multiple industry awards, it's the toolkit that keeps forms fast, data clean, and customer journeys completely friction-free. Postcoder's address lookup lets customers find their address in seconds — whether they type a postcode, begin entering a street name, or search by geographic coordinates. The service draws on Royal Mail PAF, Multiple Residence data, Ordnance Survey AddressBase, and international address databases spanning 249 countries, delivering consistently high match rates both in the UK and overseas. Beyond addresses, Postcoder packages a full suite of contact data tools into a single API integration: - Bank account validation: Confirm sort code and account number combinations in real time, retrieve branch-level details, and establish direct debit eligibility before a payment mandate is submitted. - Email validation: Go beyond syntax checks to assess domain health, detect disposable addresses, and score deliverability risk, keeping CRM lists and transactional inboxes reliable. - Mobile number validation: Confirm whether a mobile is live and reachable across more than 200 countries, cutting wasted spend on undeliverable SMS communications. - OTP verification: Add an SMS-based one-time password layer to sign-up, login, or checkout flows to protect accounts and verify identity at the point of entry. Rather than managing multiple vendors, businesses get one integration, one dashboard, and one support team. Getting started takes minutes — a free trial is available with no payment details required, and the documentation includes ready-to-use sample code across popular languages.
