"We have used Ideal Postcodes for many years in our applications and always found the service reliable and quick to respond. One useful feature is that the UPRN is returned as part of the lookup, which enables us to bring data together from different sources in a reliable format. This is extremely useful for us to build a profile and history of the property, that we can share with our agents and users"
