Mistakes when calling the US numbers, and how to avoid them

Calling a number might seem like a straightforward task, but these common mistakes show that it’s not always that simple. Let’s break down the top mistakes people make when dialling US numbers, and how to avoid them.

Area code

Omitting the US area code

Often, the area code isn’t required when dialing a number within your own local area in the US. This can create a habit of not including it when calling numbers outside your area. However, omitting the area code will result in an incorrect phone number.

There are approximately 335 area codes in the US. Each one is a three-digit number that identifies a specific geographic region, and it must be entered first when dialing a local US phone number. The same city might have more than one area code.

Incorrect number format

If you wish to contact a business by copying the number from its website, it’s often published with additional symbols such as parentheses or dashes. Some people might also share their phone numbers with these symbols.

Most modern smartphones can handle such symbols. However, extra characters such as periods, slashes, or any other unnecessary symbols or numbers can cause errors. To avoid such errors, delete all extra symbols from the number before hitting the call button, or if the call fails.

Including an extra zero

Local phone numbers, when calling from within the US, must be dialed without a zero before the area code. The local dialing format starts with a three-digit area code, not with a zero.

Skipping the international exit code

To dial a US phone number from abroad, you need to include the international exit code, also known as the international direct dial code (IDD code), which is usually 00. In many cases, it can also be replaced with the + symbol. A common mistake is to skip the international exit code, which will result in a failed call attempt.

Please note that in some countries, the exit code might be different. You can always check your carrier’s dialing guide before calling or if a call doesn’t connect.

Omitting the US country code

What is the country code to call the US? The US country code is always 1. When calling from abroad, include this code along with your country’s international exit code. To dial a US number, use 001 or +1, depending on the exit code of the country you are in.

Calling the US locally and internationally

local

US phone number dialing follows the NANP (North American Numbering Plan) format, which we will explain in more detail.

Important: In regions that have adopted ten-digit dialing, you need to dial 1 before the area code. This even applies to local calls. For additional details on ten-digit dialing, please visit the Federal Communications Commission (FCC).

When calling within the United States, follow these steps:

  • Dial the area code (3 digits). In some cases, if you are calling within the same area, the area code may not be required.
  • Enter the local number, which consists of: exchange code - the first 3 digits of the local number, subscriber number - the last four digits

Example of a local US number dialing: suppose the number is 646-814-2XXX

  • Area code: 646
  • Exchange code: 814
  • Subscriber number: 2XXX
international

International calling rules follow the E.164 numbering format. However, the international exit code varies by country. Let’s take a closer look at how it works.

When calling the US from another country, the process is similar to local dialing but with two additional steps: international exit code and US country code for international calls.

  1. Dial the international exit code. It is usually 00 or the +.
    If the call does not connect, check your carrier’s dialing guide. Some countries (for example, Japan) use different exit codes.
  2. Dial the US country code, 1.
  3. Enter the three-digit area code.
  4. Dial the three-digit exchange code.
  5. Dial the four-digit subscriber number.

Example of an international US number dialing:

Let’s use the same number from the previous example, but in international format:
001-646-814-2XXX or +1-646-814-2XXX

  • International exit code: 00 or +
  • US country code: 1
  • Area code: 646
  • Exchange code: 814
  • Subscriber number: 2XXX

How to determine if a phone number is landline or mobile

You might wonder how to determine whether a phone number is a US mobile number or a landline. While in many countries you can see this by looking at the number’s prefix, this is not possible in the US or Canada.

Phone numbers are tied to a location, not to whether they’re mobile or landline. A number can move between the two without changing. As a result, you cannot reliably identify the type of line just by looking at the number.

What to know before calling the US

Timezone
Time zones

The US has six main time zones. While it might be 10 a.m. in your city, for example, New York, it is still 7 a.m. in Oregon, which is usually not the best time to receive a call.

Clock
Daylight Saving Time (DST)

Not all states follow Daylight Saving Time. To avoid frustrating customers or having your number blocked, always check the current local time before calling.

Earth care
International exit code

To call from outside the US, first dial the international exit code or IDD code, which is usually 00, or use the + symbol.

Ringer volume
The US country code

Then enter the US country code, 1, followed by the area code, exchange code, and the subscriber’s number. For a detailed guide, see the section “Calling the US locally and internationally.”

Number pad
Extra symbols

Avoid entering extra symbols like dashes or parentheses, or even extra spaces before dialing or if the call fails. Most smartphones nowadays can handle some symbols, but older phones, or adding some extra characters (periods, dashes) might result in a failed call.

Wallet
Call costs

Check call costs and your carrier’s rules, as some regions may have specific dialing requirements.

US phone number components

A US phone number has three components, or parts: area code, exchange code, and subscriber's number.

  • Area Code is the first three digits for the area, for example 951 for Arlington, CA, or 510 for Richmond.
  • Exchange Code is the next three digits that narrow the location within the area code.
  • Subscriber Number is the final four digits that identify the specific line. This allows the call to reach the intended recipient.
