Location precision.
It’s the thing that separates PostTag from everyday address lookup services. And helps our clients get closer to achieving their CO2 emission reduction targets
PostTag’s Destination Data Engine uses multiple databases to provide a verification accuracy and location precision not seen until now.
PostTag is a trusted partner of the biggest and the best














First, we get the address right.
Then we get drivers right there.
First time, not next time.
Near enough isn’t good enough.
With nearly 60% of UK households an average of a football pitch away from where navigation systems take a driver, PostTag’s location precision means less time searching and more delivering.
Getting there first time saves time – that’s the PostTag difference
PostTag’s Destination Data Engine is processing over 3,000 address validations every minute, returning precise longitude and latitude details for each one
PostTag is the only system that supports eCommerce customers’ basket completion
The PostTag platform is truly frictionless, because we “push” the driver to the right address. Other systems we’ve looked at do the opposite – they ask the customer to generate a locator code, or even create and remember a few random words to “pull” the driver to their address.Sorry, but that’s just too much effort.
We know that if you prolong the ordering process with visible hurdles you reduce the likelihood of that customer completing the order. Less friction equals more sales.
