How to Call the US from Ireland? (A 2024 Helpful Guide)

Initially, check whether your US phone service provider allows you to make international calls. Also, ensure your mobile phone is unlocked to use an international sim, as some phones are locked to a specific country. 

There are a few things to remember before calling the US from Ireland.
 

• Exit code of Ireland (00)
• Country code of the US (1)

To dial the US from Ireland, follow these four general steps.

Step 1: Enter the Ireland Exit Code

Before making an international call, you must use the current country's exit code. For Ireland, its exit code is 00.

Step 2: Enter the US Country Code

Every nation has a unique one or two-digit country code. The US code is one (1) and should come after Ireland’s exit code.

Step 3: Dial the US Area Code/Toll-Free Code

After entering the exit and country code, include the US area code you want to connect to. The US has as many as 335 area codes; you should know the specific area code you want to call.

There are many ways to make an international call. Let’s discuss some popular ways to reach the US from Ireland.

The dialing procedure for both the landline and mobile is the same. Follow the call format as mentioned earlier, “exit code of Ireland (00), the US country code(1), the three-digit area code (XXX) where you want to dial, and the seven-digit phone number (xxx - xxxx)”.

Your number should look like “00-1-xxx-xxx-xxxx”.

You can also use + instead of 00 while calling from mobile phones.

A prepaid calling card is a credit card-sized card used to pay for phone services. Its main application is to make international calls at reduced cost and provide a cost-effective communication option. These cards come with their access number and PIN and can be used with any phone system.

A prepaid can be of both physical and virtual form. The physical prepaid card comes with a printed access number and PIN, usually hidden under its scratch-off coating, while an access number and PIN are sent via email for a virtual calling card.

To dial using a calling card, one must use the following steps.
 

1. Buy a calling card (either online or in a retail store)
2. Dial the Access Number  of the card
3. Enter the PIN 
4. Dial the US phone number. Use the  phone number format as:
    
   • Exit code of Ireland
   • The US Country Code 
   • Area Code of the US
   • Recipient's Phone Number

The Internet is the most cost-effective way to contact the US. People can also use social media applications such as Viber, Facebook Messenger, or WhatsApp to contact each other for business or personal purposes.

Alternatively, you can rely on Voice over Internet Protocol (VoIP) services for international calls. VoIP allows you to buy local mobile phone numbers and access many features unavailable in traditional phone networks, such as a unified call box, call analytics, and sentiment analysis.
 

Apart from remembering the perfect calling format, one should also know the time zone difference between both countries.

If it’s for a business purpose, the ideal working hours in the US are between 9 AM and 5 PM. For example, to call your recipient in New York (EST) at 9 AM, you need to place a call from Ireland at 2 PM Dublin time.

Contacting the United States from Ireland can be challenging, so understanding the time zone difference between the two countries is essential.

For reference, you can consider the time zone illustrated below.
