Address Validation / Verification Software


Our 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 is captured by your organisation.

We provide accurate global address validation and address cleansing services and software. Suitable for organisations of all sizes, our address software is fast, robust and easy to use.

To get the best return on your valuable customer address data, we recommend you validate against a rules-based solution, to intelligently assess each address element and return the most accurate match.

Whether these addresses are entered via web forms or online checkout, or your employees enter them via your Customer Relationship Management (CRM) system, our advanced address verification software will ensure its accuracy.

Accuracy: Our rules-based solutions and services intelligently assess and match each address – that’s why our accuracy is trusted by High Street Banks, Police Forces, and commercial organisations of all sizes.

Support: Support is backed by the specialists that have written the software in-house. This means you get  access to their expertise and problem-solving capabilities.

Knowledge: We created the first address data software in 1982 and the sheer amount of data we have processed in that time sets us apart from everyone else in the market. So if we do things a little differently from others, it might be because we have information that they don’t.

Case Study

Tombola Case Study

Tombola is an award winning, UK-based gambling company. They initially approached Hopewiser ahead of sponsoring one of the most successful TV shows in the UK.

In previous years, their address lookup providers struggled to handle the amount of lookups required during this busy period. This meant, they could not confidently guarantee that the address lookup service would not go down at critical times, when a high number of players wanted to join. This was causing great concern for the company, as it potentially meant losing revenue and wasting large amounts of advertising money.
