Every customer expects a smooth journey – from checkout to delivery. But a wrong address, a missing detail, or a misplaced pin can turn a great experience into a frustrating one. PostTag eliminates address errors before they happen, ensuring customers get what they ordered – without delays, confusion, or friction.
One system. One seamless experience.
PostTag is the only fully end-to-end address system that connects the front-end customer experience with back-end delivery efficiency ensuring both work together flawlessly.
Powered by our Destination Data Engine™, we validate and verify over 5 million addresses daily, correcting errors, filling in missing details, and pinpointing exact locations – so businesses and their customers never have to think twice about an address.
Because the customer journey starts the moment they enter their address, that moment needs to be seamless.
Only PostTag offers a complete end-to-end addressing system – So you can choose the components you need

ADDRESS LOOKUP
Standard. Reliable. Expected.
At checkout, customers enter their address – it’s a basic step every retailer provides. PostTag ensures this process is fast, seamless, and error-free, helping businesses capture customer addresses accurately while keeping form completion rates high.
With built-in validation and standardisation, PostTag’s Address Lookup:
- Reduces errors by automatically correcting formatting and typos
- Speeds up checkout with auto-complete suggestions
- Works across all major platforms for easy integration
Unlike regular PAF resellers, with PostTag you can add on features to provide Location Precision, Address Verification and even Custom Mapping – a full suite of products to get you precisely to the right place, first time, every time.

ADDRESS VERIFICATION
More than just matching addresses. PostTag verifies the exact location.
Other tools check if an address exists. Only PostTag confirms, corrects, completes and ensures every address is real and deliverable.
Why it matters:
By validating addresses before they’re used, businesses can:
- Reduce failed deliveries, delays and returned orders
- Speed up checkout and account registration
- Ensure accurate, standardised address data across all platforms
How does it work?
PostTag’s Destination Data Engine™ pulls from multiple authoritative sources including PostTag’s proprietary database to validate, correct, and precisely locate any address, whether it’s a home, office, or complex building.
