Benefits of Address Lookup



High quality data

Increased conversions

Storing complete, high quality address data improves business intelligence, increases deliverability and enhances the response rate from sales and marketing efforts.

Just like predictive text, predictive address uses intelligent type-ahead technology to reduce address entry time by up to 80-percent – all without compromising on quality.

Easy Integration

Designed with you in mind, our address lookup services are quick and easy to use, allowing you to capture valid address data in real-time, all via a single, seamlessly integrated API.

Secure & Resilient

We are fully ISO27001:2013 certified so you can be confident that your data is safe and secure backed by high availability, highly resilient infrastructure

Enhanced satisfaction

Easier website usability, faster checkouts, minimized friction – what more could your customers want? Address validation can cut cart abandonments and boost your reputation.

How Does PredictiveAddress Work?

PredictiveAddress is our industry-leading Autocomplete 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 variety of addresses they can choose from (matching their already written criteria).​​ This list is real-time generated, allowing for a more accurate input.

Improve your customer experience with our tool's built-in 'Fuzzy Logic'. Our 'Fuzzy Logic' means that you can start at any point in the address, misspell a word or type ''four'' instead of ''4''. 

Enter up to 20 addresses and try PredictiveAddress™ for yourself! Remember, you can start anywhere in the address.

Better user experience

Autocomplete your customers addresses for a smooth and convenient checkout process.

Accurate Data

Obtain accurate & valid addresses at point of capture, eliminating poor information in your CRM.

Improve Deliverability Results

Reduce the possibility of failed deliveries by up to 92%.

Predictive Address: Verify Address at Point of Capture

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, PredictiveAddress will start to formulate a list of options to choose from. This even works by simply inserting a postcode.

We all make mistakes, and our PredictiveAddress AI knows that!

Data8's AI can look past the following: Extra Spaces - Missing Spaces - Common Typos - Abbreviated Words - Transposed Characters

Whether you are adding extra spaces in between words, or adding spaces within the word itself, our Fuzzy Logic AI will overcome the mistake of too many keystrokes. 

Just like having too many spaces, Fuzzy Logic can predict the address without the need of spaces at all!

Most people nowadays are using mobile phones. This means that we are more prone to the odd typo or two. Luckily, Fuzzy Logic can work around this. 

Could you spell an address in multiple different ways? Our Fuzzy Logic AI looks past phonetic spellings, providing the user with words that sound the same but are spelt differently. 

Is it 'Abbey Road' or 'Abbey Rd'? Luckily Data8's Fuzzy Logic AI believes that both could mean the same thing!

Not sure if the 'i' comes before the 'e'? Data8's fuzzy logic can still predict an address with transposed characters. Meaning the user can get away with a few spelling mistakes.

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: Verify Address at the Point of Capture

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.

Enter up to 10 postcodes and try Postcode Lookup for yourself!
