How does it work?

How Address Validation works

We pride ourselves on giving our customers the option between two different formats of Address Validation, PredictiveAddress and Postcode Lookup. Both of these methods provide customers with unique ways on acquiring formatted, accurate and valid address data.

Our Address Validation Tools call on a wide range of sources, including:

  • Royal Mail PAF (Postcode Address File), containing over 30 million records, updated daily
  • Data8 Business Universe, containing 2 million+ B2B records that you won't find from any other provider
  • Not-yet-built and multi-residence data; identify premises under construction and premises with shared letterboxes with confidence
  • Global Coverage for over 250 countries, including USPS and Eircode


How Does PredictiveAddress Work?

PredictiveAddress is the Address Validation feature that enables a customer to simply start typing their address into the blank field. As they type in their address, a drop-down menu will appear below the blank field, providing the customer with a real-time update on a variety of addresses they can choose from (matching their already written criteria).​​ Our 'Fuzzy Logic' means that you can start at any point in the address, misspell a word or type ''four'' instead of ''4''. 

Address Autocomplete, regardless of where you start

Through the use of a sophisticated AI, a customer may start writing from any part of their address. Once the customer starts typing, the PredictiveAddress tool will start to formulate a list of options to choose from. This even works by simply inserting a postcode.

How Does Postcode Lookup Work?

Postcode Lookup works in a similar way to PredictiveAddress in that it provides a customer with a list of addresses to choose from. However, the difference here is that the list of addresses formulated will only be displayed after the customer inserts a UK postcode AND clicks on a button that activates the search.

Postcode Lookup: Same data, different method

Using the same database as PredictiveAddress, the results provided from the search will mirror the same results that would be provided from PredictiveAddress.
