Do more business for less work with the NZBN

Posted: 5 June 2018

Using the New Zealand Business Number (NZBN) means you can update key business information, such as a new phone number, and not have to worry about letting all your business contacts know.

The NZBN is a unique identifier for every business in New Zealand, designed to make it faster and easier for businesses to interact and transact with each other, and with government.

Key information about each business is held on the NZBN Register. By connecting to the NZBN, users are notified as soon as one of the organisations they work with updates their information. It's instant, it’s online, and using the NZBN Register is free.

There are several tools available to NZBN users:

  • Get started with data matching
    The free data matching service makes it easy to keep track of businesses you work with. The NZBN team can take a list of your customers/suppliers and match these securely to their NZBNs. Being able to uniquely identify each business reduces duplicate records in your systems, reduces risk and offers you more certainty about your business networks.
  • Watchlists and alerts
    You can create an online ‘watchlist’ for the businesses you engage with and receive email alerts when they change key information (like a phone number or contact email address).
  • Connect via the API
    The Application Programming Interface (API) is a useful tool for managing information if you have a large number of businesses in your network. Linking your digital systems to the NZBN API can simplify processes such as loading new customer or supplier information. The API pulls information from the NZBN Register about your new customer so they won’t have to manually enter basic information like their address and phone number.

It's the future of business

The NZBN will create a transactional environment with greater certainty of identity, more reliable information and less duplication. Connecting to the NZBN will save your business time and money, because you can get the right information, about the right organisations, at the right time.
