New Zealand Phone Number Format: How +64 Numbers Are Built
A New Zealand number can look confusing from the outside — sometimes nine digits, sometimes ten, sometimes with a 0 and sometimes without. The logic underneath is actually simple.
Whether you're calling a supplier in Auckland, setting up a virtual line, or just saving a contact correctly, getting the format right means your calls connect the first time.
This guide breaks down every part of a New Zealand number: the country code, the five area codes, mobile prefixes, and how the digits shift when you dial from abroad.
THE BUILDING BLOCKS OF A NEW ZEALAND NUMBER
Every New Zealand number is made of three parts: a country code, an area or mobile prefix, and the local subscriber number.
The country code for New Zealand is +64. You use it whenever you call into the country from outside.
A Landline Example, Broken Down
Take an Auckland landline written locally as 09 123 4567. The 09 is the area code, and 123 4567 is the 7-digit local number — nine digits total.
From overseas it becomes +64 9 123 4567. The leading 0 drops off and +64 takes its place.
A Mobile Example, Broken Down
A New Zealand mobile written locally looks like 021 123 4567. The 021 is the carrier prefix; the rest is the subscriber number.
From abroad that becomes +64 21 123 4567 — again, the leading 0 is removed.
THE FIVE NEW ZEALAND AREA CODES
Landlines in New Zealand use just five geographic area codes. Each covers a broad region rather than a single city.
| Area Code | Region Covered |
|---|---|
| 03 | South Island and Chatham Islands |
| 04 | Wellington |
| 06 | Lower North Island (Taranaki, Hawke's Bay, Manawatū) |
| 07 | Central North Island (Waikato, Bay of Plenty) |
| 09 | Auckland and Northland |
Notice there's no 01, 02, 05, or 08 in this list — those ranges are used for other purposes, including mobiles.
Why Only Five?
New Zealand is a small country by population, so it never needed the dense grid of area codes used in larger nations.
Five regional codes comfortably cover the entire fixed-line network.

HOW MOBILE NUMBERS DIFFER
New Zealand mobile numbers don't use geographic area codes at all. They all start with 02.
The Common Mobile Prefixes
The digit after 02 historically signaled the carrier. The three you'll see most are:
- 021 — the longest-running and most common mobile prefix
- 022 — widely used across newer connections
- 027 — another standard prefix in regular use
Because mobiles aren't tied to a region, the prefix tells you nothing about where the person is — only that it's a mobile line.
Quick tip: Not sure whether a +64 number is a landline or a mobile? MCM's free number lookup tool identifies the line type and region instantly, which helps you predict call costs before dialing.
HOW TO DIAL A NEW ZEALAND NUMBER
The digits you dial depend entirely on where you're calling from. Here's each case.
Calling Within New Zealand
For a local call inside the same area code, dial just the 7-digit number. For a call to another region, dial the full number including the area code — for example 09 123 4567.
Mobiles always need the full 02x prefix, wherever you are in the country.
Calling New Zealand From Abroad
Dial your country's exit code (or +), then 64, then the number without its leading 0.
From the US, an Auckland landline is 011 64 9 123 4567. A mobile is 011 64 21 123 4567.
Calling Out of New Zealand
To call internationally from New Zealand, dial the exit code 00 (or +), then the destination country code, then the number.
For example, a UK landline would be 00 44 followed by the local number minus its leading 0.

OTHER NUMBER TYPES YOU'LL ENCOUNTER
Beyond standard landlines and mobiles, a few special ranges show up in New Zealand.
Toll-Free and Premium Numbers
Toll-free numbers usually start with 0800 and are free for the caller — common for customer support lines.
Premium-rate numbers, often starting 0900, charge the caller a higher rate and are used for paid services.
Virtual New Zealand Numbers
A virtual number gives you a local +64 presence without a physical line in the country. Calls route over the internet to wherever you actually are.
This is popular with businesses that want a local Auckland or Wellington number for customers while operating from overseas.

FAQs
What is the country code for New Zealand?
New Zealand's country code is +64. You dial it after your own country's exit code (or the + symbol) whenever you call a New Zealand number from outside the country.
How many digits is a New Zealand phone number?
A landline is nine digits in total — a two-digit area code plus a seven-digit local number. Mobiles vary slightly but generally run nine to ten digits including the 02x prefix.
Do I drop the zero when calling New Zealand from abroad?
Yes. The leading 0 is a domestic trunk prefix used only within New Zealand. When dialing internationally, +64 replaces it, so an Auckland 09 number becomes +64 9.
How do I know if a +64 number is a mobile or a landline?
Check the prefix after +64. Landlines use the area codes 3, 4, 6, 7, or 9, while mobiles start with 2 (locally 02, shown as +64 2 internationally).
What are the main mobile prefixes in New Zealand?
The three most common are 021, 022, and 027. They originally indicated the carrier, but with number portability the prefix no longer reliably identifies a person's network.
Can I get a New Zealand number without living there?
Yes. A virtual +64 number gives you a local New Zealand presence while calls route over the internet to wherever you are — a common setup for businesses serving NZ customers from abroad.
What does an 0800 New Zealand number mean?
An 0800 number is toll-free — the call is free for the person dialing it, with the cost covered by the business that owns the line. They're widely used for customer service in New Zealand.
