Sole traders: Got your NZ Business Number?

Get your NZ Business Number

The New Zealand Business Number (NZBN) is a globally unique identifier available to all Kiwi businesses, including sole traders, and it comes with a growing list of benefits.

What's the NZBN?

The New Zealand Business Number (NZBN) is a unique identifier available to every business in New Zealand. It provides an easy way to identify different businesses, and to share and update business information.

New Zealand companies and public sector agencies are automatically given an NZBN. Sole traders, partnerships and trusts can register for one.

Information about each business is listed in a secure online register, managed by the Ministry of Business, Innovation and Employment.

Why get an NZBN

It’s free to get an NZBN. Any business operating in New Zealand can get one – whether you’re a sole trader working from home, or a multi-national organisation. An NZBN:

identifies you as a real NZ business
should save you time by reducing the number of places you need to update your business information when something changes
makes it easy to check details for new suppliers or clients
is a globally recognised number, so when you use it, anyone across the world can recognise you.
As more businesses get and use their NZBN, it will get easier to invoice customers, pay bills and apply for credit. You won’t have to repeat the same basic information multiple times, saving you time and money.

What it means for sole traders

If you’re a sole trader, you can use your NZBN to:

prove that your business is real and valid
easily share and update your business information
speed up your interactions with government agencies such as Inland Revenue, ACC and the Ministry of Business, Innovation and Employment
auto-fill your business information in online forms that require your NZBN.

How to get an NZBN

Some types of businesses, like registered companies, are automatically given an NZBN. Sole traders, partnerships and trusts need to sign up for one separately.

To get an NZBN, you’ll need a RealMe login.
