The Not Yet Built (NYB) data provides valuable insights into postcodes and addresses for properties that are currently under construction or in the planning stage. This document outlines the significance of NYB data, its applications, and the benefits it offers to various organizations.

NYB data serves as a powerful marketing tool utilized by organizations across multiple sectors. It offers a comprehensive view of future developments, enabling businesses to strategize effectively.

• Access to New Markets: NYB data allows organizations to identify potential areas for future developments, opening doors to new market opportunities.

• Accurate and Timely Information: The data is updated daily with information from Royal Mail, which ensures that users have access to the most current data.

• Competitive Advantage: By understanding where potential customers will live and work, businesses can shape their marketing strategies to gain a competitive edge.

The NYB data is powered by the Postcode Address File (PAF), which bridges the gap in address information. In the UK, approximately 100,000 new properties are constructed annually, and the NYB dataset contains over 500,000 records, making it a robust resource for market analysis.

The Autoaddress service includes NYB data as part of the UK dataset at no additional cost or setup fees. This data is returned in the same format as built addresses, ensuring seamless integration into existing systems.

For determining if an address is Not Yet Built, the returned ID for these addresses will begin with GB100000000.

The following is a sample JSON response for a NYB address.
