AutoPostcode
The UK Data Validation Engine.
Real-time postcode, address, phone, email and bank validation infrastructure — one API key that stops bad data at the point of capture, cutting failed deliveries, bounced mail, fraud and payment errors for any UK business.
The Problem
Bad Data Costs You Every Day.
Every checkout, sign-up and payment form is a chance for wrong data to enter your business. A mistyped postcode, a dead phone number, a bounced email or a transposed sort code doesn't fail loudly — it fails quietly, days later, as a missed delivery, an undelivered OTP, a spam-flagged campaign or money sent to the wrong account.
Failed Deliveries
Wrong or incomplete addresses become re-shipments, refunds and support tickets that quietly eat margin on every order.
Slow, Error-Prone Checkouts
Customers hand-typing five address fields on mobile abandon carts and introduce typos on every line.
Undeliverable Email
Bad addresses bounce, damage sender reputation and push future mail into spam folders.
Wasted SMS & OTP Spend
Dead, VoIP and mistyped numbers burn messaging budget and block legitimate sign-ins.
Failed & Misdirected Payments
Wrong sort codes and account numbers cause returns, chargebacks and authorised push payment fraud.
Fragmented Tooling
Teams stitch together four or five vendors, contracts and API keys just to keep basic customer data clean.
Product
A Data-Validation Engine.
AutoPostcode turns data capture from a source of errors into a source of clean, structured, verified records. Validate the address, the phone, the email and the bank details — in real time, at the point of entry, from a single integration.
Postcode Lookup & Autocomplete
Verified Royal Mail PAF addresses suggested as the customer types — turning a five-field form into a single tap.
Address Verification
Structured, deliverable UK addresses with consistent formatting for shipping labels, CRM and downstream systems.
Phone Validation
Format, line type and carrier checks, plus live HLR lookups that confirm a SIM is active and reachable right now.
Email Validation
Syntax, domain, MX and mailbox-risk checks with typo correction and a clear valid / invalid / risky verdict.
Bank Validation
Instant modulus checking plus Confirmation of Payee (CoP) name matching to stop failed and misdirected payments.
One Key, One Credit Pool
Every check runs from a single API key and shared balance — no juggling vendors, contracts or integrations.
Process
How It Works
Drop In One Integration
Add the REST API to any checkout or form, or install the no-code WooCommerce / WordPress plugin. One API key unlocks every validation product.
Validate at the Point of Capture
As the customer types, AutoPostcode suggests verified addresses, checks the phone and email, and confirms bank details — inline, in real time, before submit.
Get a Clear, Actionable Verdict
Every check returns structured data and a simple verdict — valid, invalid or risky — plus suggested corrections, so your logic stays simple and your forms stay fast.
Store Clean, Structured Data
Only deliverable addresses, reachable numbers, real inboxes and valid accounts make it into your database — consistently formatted for every downstream system.
Draw From One Credit Pool
Every product bills from the same shared pool. Top up once, monitor usage in one dashboard, and scale checks across your whole stack.
Infrastructure
Data-Quality
Infrastructure.
AutoPostcode is not a lookup widget. Not a single-purpose plugin. Not another vendor to bolt on.
It is a unified UK data-validation layer — an API-native infrastructure that verifies identity, contact and payment data across every product from one integration.

Category Shift
Why Unified Data Validation Wins.
Structurally cheaper. Structurally faster. Structurally cleaner. Structurally simpler to integrate — than every incumbent model.
Legacy address vendors sell one product — a postcode lookup — on enterprise contracts and long integrations. AutoPostcode ships address, phone, email and bank validation from a single key with self-serve, pay-as-you-go credits.
Point solutions each solve one slice of data quality, so teams stitch together four vendors, four bills and four integrations. AutoPostcode collapses that into one API and one credit pool.
DIY validation — home-grown regex and manual checks — catches typos but never confirms a live SIM, a real inbox or a valid bank account. AutoPostcode verifies against authoritative sources in real time.
Old economics
Enterprise contracts per check
Legacy vendors charge annual minimums for a single lookup.
New economics
One shared balance.
Every check, self-serve, from a single credit pool.
