The New Zealand Business Number

We administer the New Zealand Business Number which is a free, globally unique identifier that makes it faster and easier for businesses to connect and interact.

About the New Zealand Business Number

The New Zealand Business Number (NZBN) is transforming the way New Zealanders do business.

An NZBN is available to all New Zealand businesses. It links to the information organisations are most often asked to share, like a phone number and trading name.

By making it easier to share information, Kiwis can stop repeating the same details multiple times when working with each other or with government – and spend more time growing their businesses.

The benefits of NZBN

Accuracy during times of change

Business information is held securely on the NZBN Register and is always provided by the business itself. When your details change, it’s quick and easy to update so everyone in your business network can be notified at once.

Do business with confidence

Having an NZBN shows that a business is real, This gives your customers more confidence in dealing with you. Ask other businesses for their NZBN so you can be certain exactly who you’re working with.

It’s for every Kiwi business

Any business can get a free NZBN, regardless of size, including sole traders, partnerships, trusts, government agencies and companies.

Government's role

More than 50 government agencies are currently integrating the NZBN into their systems and processes. A shared network of up-to-date information will reduce the duplication of records across government agencies. This will mean businesses won’t have to keep repeating their details when dealing with different agencies.

This is just one of the ways the NZBN will make it faster and easier for businesses to work with government.
