Address Validation / Verification Software


Our UK address validation will ensure your customer data is always verified and accurate at the point of entry.


Customer address data that isn’t verified against an up-to-date, reputable source will always lead to some inaccuracies when it’s captured by your organisation.

And capturing incorrect addresses inevitably means higher costs and lower ROI: more returns, undelivered mail, abandoned online shopping transactions and frustrated customers who may not become repeat customers.

To get the best return on your valuable customer data, it’s essential it’s validated and accurate from day one; you need to verify addresses at the point of entry against the 30 million business and residential addresses that exist in the UK.

Whether these addresses are submitted by your customers via web forms or during online checkout, or your employees enter it via your chosen Customer Relationship Management (CRM) system, our advanced address verification software will help you validate it and ensure its accuracy before it’s captured.

Comprehensive, Extensible & Cost Efficient

Our address validation is powered by the Royal Mail Postcode Address File (PAF) that gives you access to almost 30-million UK postal addresses and 1.8 million UK postcodes plus regular PAF updates to keep your address capture as accurate as possible.

Our address validation solution offers easy integration with the major CRM systems including Microsoft Dynamics, Sage CRM, and IBM WebSphere. It also includes a wide range of APIs and plug-ins for your website forms and applications. We can even add additional datasets such as Ordnance Survey, International and Companies House data.

Case Study

Address Validation / Verification Case Study


A leading travel agent had a desire to move to a cloud based address validation service, but had been told by one of our competitors that this wasn’t possible because of the large amount of daily data requests.

Hopewiser introduced the organisation to their Pay Per Click Address Lookup solution. The Travel organisation took the REST API solution and was able to install the software onto their systems quickly and easily. They had no downtime or support problems and have been running the software for over two years.
