Calling the US from New Zealand is easier than you might think. Whether you’re contacting a landline or a personal cell, it’ll take just a few minutes to enter the numbers.

This guide will walk through the four steps required to call the US from NZ. We’ll also explore the overall cost, time zone differences, and how you can make unlimited calls without paying additional fees.

How to call the USA from a New Zealand phone number

You’ll need four things to call a US phone number from NZ: an exit code, a country code, an area code, and a seven-digit phone number.

Let’s walk through an example together.

1. The exit code

Exit codes tell your phone service provider that you’re calling someone outside of the country. In New Zealand, the exit code is 00.

2. The country code

You need to tell your phone company which country you’re trying to reach — in this case, the USA.

Just enter the United States’ country code: 1.

3. The area code

The United States has more than 325 area codes (also known as calling codes) across all fifty states.

Thankfully, most contacts will include their area code information along with their phone number. If not, you can easily look up their city’s dialing code through a quick online search.

Some of the most common area codes in the US are:

CityCode
Boston617
Chicago312, 773, 872
Dallas214, 469, 972
Denver303, 720
Detroit313
Houston713, 281, 832
Los Angeles323, 213
New York City212, 646, 917
Philadelphia215, 267, 445
Phoenix602
San Antonio210, 726
San Diego619, 858
San Francisco415, 628
San Jose408, 669
Seattle206

You can use sites like All Area Codes to look up other prefixes in the US.

4. The seven-digit phone number

The final step is to enter your contact’s seven-digit phone number. Both landlines and cell phones share the same number of digits, so the process will be the same no matter what device you call. The format is generally 123 – 4567, not including the area code.

This is all you need to call a US phone number from New Zealand.

To summarize, you’ll need to enter an exit code, country code, area code, and phone number.

Here’s an example of what this might look like:

00 (NZ exit code) 1 (US country code) 347 (NYC area code) 123 – 4567 (phone number)

In other words:

00 – 1 – 347 – 123 – 4567

How much does it cost to make international calls to the US from New Zealand?

There are no set calling rates for reaching US contacts from New Zealand.

Traditional phone carriers like 2degrees, Vodafone, and Spark charge a set price per minute for international calls. You won’t have to pay when calling a toll-free number, but contacting a local number will cost anywhere from a few pennies to a few dollars per minute. You may end up paying over a hundred dollars for a one-hour call — not ideal for small business owners.

If you’re interested in a different method, you could instead opt to purchase a calling card with prepaid international minutes. While this may be somewhat cheaper and a bit easier to manage, you’ll still need to worry about what happens when your minutes run out. Some companies will cut the line completely when your card empties, potentially ending your connection in the middle of a conversation.

Per-minute pricing is a frustrating and expensive way of paying for international calls. You can instead reach American contacts for a set monthly price — potentially saving you hundreds over time.

With OpenPhone, you can make unlimited calls to the US from Zealand for just $13 per month per user.

If you make frequent calls to the United States or looking to expand your customer base to the States, you can get a US number with OpenPhone that you can use anywhere you have internet access. US contacts are more likely to pick up numbers they recognize, which means they’ll respond even better to familiar area codes. 

Additionally, having a US number shows your business caters to customers there — and not just those in New Zealand.

How to factor in time zone differences calling the US from New Zealand

The United States has six separate zones for each of the 50 states. This discrepancy can make it tricky to reach US contacts at a convenient time and complicates meetings, conferences, and video calls.

Here are the time differences you can expect if you live in Auckland, Wellington, Christchurch, or other inland cities:

  • Eastern Daylight Time (EDT): You are 17 hours ahead of callers on Eastern time. Phone calls at 12 PM will reach the US at 7 PM the previous day.
  • Central Daylight Time (CDT): You are 18 hours ahead of callers on Central time. Phone calls at 12 PM will reach the US at 6 PM the previous day.
  • Mountain Daylight Time (MDT): You are 19 hours ahead of callers on Mountain time. Phone calls at 12 PM will reach the US at 5 PM the previous day.
  • Pacific Daylight Time (PDT): You are 20 hours ahead of callers on Pacific time. Phone calls at 12 PM will reach the US at 4 PM the previous day.
  • Alaskan Daylight Time (AKDT): You are 21 hours ahead of callers on Alaskan time. Phone calls at 12 PM will reach the US at 3 PM the previous day.
  • Hawaii-Aleutian Daylight Time (HST): You are 22 hours ahead of callers on Hawaii-Aleutian time. Phone calls at 12 PM will reach the US at 2 PM the previous day.

Keep in mind that Daylight Savings will regularly change the time zone gaps between the US and NZ. To avoid further confusion, you should use tools like World Time Buddy to instantly compare time zones.
