About Address Validation

What is Address Validation Software?

Address validation is the process of verifying accurate postal addresses so deliveries are made to the correct location. This involves checking it against multiple address databases and making necessary corrections where needed.

Why is Address Validation Important?

Address validation benefits both the customer experience and business efficiency.

By implementing an address validation tool on your website, you can make in-line forms and check-out pages a much simpler process for the customer; instead of filling out every line of the address, they can instead enter the postcode and select the corresponding house number. This will improve the customer’s experience and allow them to complete their purchase in seconds.

This also enhances business efficiency; by allowing customers to confidently check out in seconds, the number of abandoned carts at checkout will significantly reduce, as well as reduce invalid addresses, ensuring 100% address accuracy for the best delivery experience possible.

By removing bad addresses, the amount of returned packages and bounced-back letters will also decrease, meaning you’ll save any additional costs relating to packaging and lost customers.

By having an in-depth & verified depth customer address database,  you’ll be able to segment your customers into specific target markets and marketing campaigns with a much higher success rate.

Where do we get our address data from?

We utilise Royal Mail PAF data containing more than 30 million postal addresses and 1.8 million postcodes. Outputs can be broken down into:

  • Street/postcode level dataset and flat file
  • GIS Table relating unit postcode to 100m OS grid references Locality, Town and Street gazetteers
  • Postcode validation tables
  • Postcode-related data such as administrative area, District and Ward codes
  • Formatted Address Extracts for mail/merge processing and area listings
  • Postcode to GIS coordinates including Lat/Long values

Address Validation for GDPR

In the UK, businesses must comply with UK GDPR, which ensures customers’ personal data is protected, accurate and up-to-date. Address verification allows you to keep address data accurate and up-to-date; by implementing it in your CRM systems, you’ll be able to enrich your data, fill in any missing address gaps and be informed when data is no longer accurate.



...which is right for you?

AutoComplete or Type Ahead, produces address matches based on what is being typed. AutoComplete does not require complete addresses or postcode and can start returning results from very few input characters.

Postcode lookups expect the full postcode details to be entered before checking to see what matches. Postcode Lookup can cut keystrokes by 80% making it much faster to find an accurate address.

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.
