Having friends and family living in the US? Or, are you planning to expand your business overseas? Either way, it has become easy to make international calls without having to worry about calling costs.

By sitting in Ireland, you can get a local number of the US or any other countries and connect with people all across the globe. Yes, it’s that simple. This post will teach us how to call America from Ireland and dial the US from Ireland using virtual calling platforms.

All you need to know is the country’s exit code, the area code of the region you are dialing to, and the mobile phone number. Let’s dive in.

How to Call USA From Ireland

International calling plans have never been this simple. With the introduction of the virtual phone system, you just need to know the calling codes and have a good internet connection. Let’s discuss the area codes for calling the US from Ireland.

Step 1: Enter the Exit Code for Ireland

Before you dial the number, make sure that you have entered the exit code of the country you are calling from. The exit code for Ireland is ‘00’ and should come before the area code and the telephone number.

Alternatively, you can use the ‘+’ symbol instead of the exit code.

Step 2: Enter the Country Code for USA

Once you have entered the exit code, you should now provide the country code for the US. Every country has its unique country code which is usually one to two digits long and must be entered while making an international call. The country code for the US is ‘1’ and must come after the exit code.

Step 3: Dial the Area Code for the US

After you have provided the Ireland exit code and the US country code, you need to dial the area code of the city or region you are making a call to. There are approximately 291 area codes in the US that are three digits long. Each city or region has its own area code. Thus, you should know which area in the US you are dialing before making a call.  Below is a table that provides the list of area codes of the major cities and regions in America.

However, keep in mind that dialing a landline number requires providing the area code, a mobile number often does not.

Step 4: Dial the US Local Phone Number

After you have entered the Ireland exit code, the US country code, and the area code, you should now dial the recipient’s telephone number. Both the landline and mobile phone numbers in the US are seven digits long.

For example, if you want to call someone living in New York City, here’s how the dialing format of a US mobile number would look like –

00-1-212-XXX-XXXX

Or

+1-212-XXX-XXX

Where ‘00’ is the exit code for Ireland, ‘1’ stands for the US country code, followed by ‘212’ which is the area code, and the seven-digit telephone number.

Area Codes of the Major Cities

Every US mobile number or landline number includes a specific area code that routes the call to the correct region. Knowing the correct area code dial is essential when calling major cities.

Incorrect area codes are a common reason international calls fail or reach the wrong recipient’s telephone number.

6 Practical Ways to Call the USA from Ireland

Choosing the right method for calling America from Ireland depends on your budget, call frequency, and whether the communication is personal or business-related. Below are the most practical and widely used options, including newer, technology-driven approaches.

1. Call From an Ireland Cell Phone or Landline

International direct calling from Ireland to the US using a cell phone or fixed line number is simple. Once you subscribe to the business phone system and get a local number, you need to follow a certain dialing format.

First, enter the exit code for Ireland. It is followed by the country code for the US, the area code dial, and the seven-digit phone number. Hence, the number would look like ‘00-1-XXX-XXXX-XXX’ or ‘+1-XXX-XXXX-XXX’.

The dialing procedure for calling the US from Ireland using either a cell phone or landline is the same. Moreover, mobile phone numbers and landline numbers in the US both follow a seven-digit format.

2. Call Using a Prepaid Calling Card

Using prepaid calling cards is one of the most common ways of making international calls. You need to purchase a local Ireland SIM card and top it up with credit. With most of the service providers, you even need to subscribe to the International calling plan.

Once that is done, you need to add the ISD code before the mobile number and start calling the US numbers. Dialing the ISD code is essential to make calls to other countries. Also note, international subscriber dialing using prepaid sim cards can be expensive if you need to make calls frequently.

3. Call via the Internet

In case you are looking to call America from Ireland in a cost-friendly way, internet calling might be the answer. Today, an increasing number of people are preferring internet calling to buying prepaid calling cards.

The growth of platforms such as WhatsApp, Google Meet, Zoom, and Skype has made it convenient to make free calls anywhere. For instance, using your Skype account paired with a good wifi connection, you can have video calls. It’s great for businesses looking to have conference calls with people across countries.

Similarly, there are virtual phone calling platforms like CallHippo that made international calling a breeze. Not only can you buy a mobile phone number of any country but also avail a large number of features that are typically not provided by traditional phone networks.

4. International Calling Plan with Your Ireland Provider

Irish telecom providers offer international calling plans that allow direct calls to any US phone number from your mobile phone or landline. These plans are convenient but often come with higher per-minute calling costs, especially for frequent or long calls.

5. VoIP Services

VoIP is one of the most cost-effective ways to make international calls from Ireland to the USA. Calls are placed over an internet connection, avoiding traditional phone networks and reducing charges significantly.

Platforms like CallHippo enable calls to US landlines and US mobile numbers at low rates while offering advanced features such as virtual US numbers, call routing, call recording, AI copilot, multi-level transfer, and CRM integration. This makes VoIP ideal for both individuals and businesses.

6. Messaging Apps (WhatsApp, Viber, Messenger)

Messaging apps offering free calls and texts over the data network when both parties use the same app. They are convenient for personal use but lack the reliability, flexibility and business features found in VoIP services.

Cost and Bill Considerations

The cost of international calls can vary significantly according to the mode you select. Most callers would think a traditional phone call continues to be the status quo, but billing realities today suggest otherwise.

1. Typical Call Charges (Cell, Landline, and VoIP)

Traditional mobile and landline calls remain the most expensive because they rely on legacy carrier networks and international termination fees. These costs increase further when roaming is involved. VoIP services route calls over the internet instead of public switched telephone networks, which explains the drastic price difference.

According to the European Commission, international phone calls made outside bundled or special international plans can exceed €1 per minute. This is why VoIP has become the preferred option for frequent callers, remote teams, and globally operating businesses.

Know This

Before making repeated international calls, check whether your mobile carrier treats them as roaming or international dialing. The billing difference can double your per-minute cost without warning.

2. How to Avoid High International Fees

Avoiding high international charges does not require complicated setups. Small adjustments in how and where you place calls can make a noticeable impact on monthly bills.

• Choose VoIP or cloud calling platforms for international calls
• Use Wi-Fi instead of mobile data whenever possible
• Avoid roaming on your mobile phone
• Compare international calling plans carefully before committing

For businesses, fixed-rate VoIP plans and bundled international minutes provide cost predictability, which is difficult to achieve with traditional carriers.

3. Using + vs ’00’ to Dial Internationally

The + symbol replaces a country’s exit code automatically and works across networks and regions. This reduces dialing errors and ensures consistency when traveling or switching carriers. Instead of remembering whether to dial 00, 011, or another exit code, using + keeps the process universal.

Key Insight

Save international contacts using the + format in your address book. This ensures calls connect correctly regardless of location or carrier.

4. When Toll-Free Numbers Are Not Free

US toll-free numbers such as 800, 888, and 877 are typically free only for callers within the United States. When dialed internationally, these numbers often incur charges, depending on your carrier and calling plan. In some cases, the call may not connect at all.

Businesses serving international customers should never assume toll-free accessibility across borders. If you buy a local phone number or virtual numbers, it will avoid this friction entirely.

Best Time to Call Ireland

Timing plays a critical role in successful international communication. The US spans multiple time zones, which creates a noticeable gap between Irish and American business hours.

1. Ireland Time vs US Time Zones

Without proper planning, calls can easily land outside working hours, leading to missed connections or delayed responses.

2. Best Time to Call for Business or Family

• Business calls: 2:00 PM–5:00 PM Ireland time
• Personal calls: Early evening Ireland time

This window aligns Irish afternoons with US mornings, when professionals are typically more available and less overwhelmed by meetings.

3. Daylight Savings Impact

Daylight savings changes in spring and fall temporarily alter the time differences between Ireland and the US. These shifts can move ideal calling windows by an hour, which is often overlooked when scheduling recurring calls or meetings.

Key Insight

For business calls, aim for US mornings. Call answer rates are higher, and decision makers are more responsive before their local workday becomes congested.
