Before you even pick up the phone, it helps to understand the components of an international call. Every international call from the USA to Ireland follows a specific sequence. This sequence ensures your call reaches the correct country, city, and individual phone line.

The Essential Dialing Sequence

To call Ireland from USA, you will always follow this pattern:

  • USA Exit Code: This tells your phone provider you are making an international call.
  • Ireland Country Code: This directs your call to Ireland.
  • Area Code (or Mobile Prefix): This narrows your call down to a specific region or mobile network within Ireland.
  • Local Phone Number: This is the specific number of the person or business you want to reach.

Let’s break down each part.


Calling Ireland from a Landline

Using a traditional landline phone to call Ireland is a common method. It requires a specific dialing sequence to ensure your call connects properly.

Step-by-Step Landline Dialing

When you make international calls to Ireland from a landline in the United States, you need to dial three key numbers before the actual local Irish phone number.

  1. Dial the USA Exit Code (011): This is the international access code for all calls originating from the United States. It tells your phone network you are calling outside the country.
  2. Dial Ireland’s Country Code (353): After the exit code, you must dial Ireland’s specific country code. This number directs your call to Ireland.
  3. Dial the Irish Area Code (without the leading ‘0’): Irish landline numbers include an area code that starts with a ‘0’. When dialing from outside Ireland, you must drop this ‘0’. For example, Dublin’s area code is normally ’01’, but you would dial just ‘1’.
  4. Dial the Local Phone Number: Finally, enter the specific local phone number you wish to reach.

Example for a Dublin landline number (e.g., 123 4567):

011 + 353 + 1 + 123 4567

Example for a Cork landline number (e.g., 21 987 6543):

011 + 353 + 21 + 987 6543

Ensure you dial each number carefully without rushing. A single incorrect digit can prevent your call from connecting.


Calling Ireland from a Mobile Phone

Calling Ireland from your mobile phone is often more convenient than a landline, especially when you are on the go. The dialing process is slightly different but still very simple.

Mobile Phone Dialing Explained

Mobile phones offer a handy shortcut for international dialing. Instead of the ‘011’ exit code, you can use a plus sign (+).

  1. Use the Plus Sign (+): On most smartphones, you can press and hold the ‘0’ key until a ‘+’ appears. This symbol automatically replaces the need for the ‘011’ exit code. It’s universally recognized as an international dialing prefix.
  2. Dial Ireland’s Country Code (353): Immediately after the ‘+’, dial Ireland’s country code. This code directs your call to the right country.
  3. Dial the Irish Mobile Number (without the leading ‘0’): Irish mobile numbers typically start with ’08x’. When calling from the USA, you must omit the leading ‘0’. For example, if the number is 087 123 4567, you would dial 87 123 4567.
  4. Dial the Rest of the Local Phone Number: Complete the number by dialing the remaining digits of the mobile phone number.

Example for an Irish mobile number (e.g., 087 123 4567):

+353 + 87 + 123 4567

Key Difference for Mobile: The main distinction is using the ‘+’ symbol instead of ‘011’ and remembering to drop the leading ‘0’ from both landline area codes and mobile prefixes. This makes calling Ireland from America very straightforward from your smartphone.


Ireland’s Dialing Codes: Understanding the Structure

To effectively call Ireland, you need to understand the country’s specific dialing code structure. This includes the country code itself and the various area codes for cities and mobile numbers.

The Country Code for Ireland

The international dialing code for Ireland is +353. This code always comes after your exit code (011 from the USA) or the ‘+’ symbol from a mobile phone. It is crucial for directing your call specifically to Ireland.

Irish Area Codes for Landlines

Ireland uses geographic area codes for its landline numbers. These codes vary depending on the region or city you are trying to reach. It’s important to remember that when dialing from outside Ireland, you must omit the leading ‘0’ from these area codes.

Here are some common Irish area codes:

City/RegionLocal Area Code (with 0)Dial from USA (without 0)
Dublin011
Cork02121
Galway09191
Limerick06161
Waterford05151
Belfast (Northern Ireland)028 (different country code for NI: +44)28 (when calling NI)

(Note: Northern Ireland is part of the UK and uses country code +44, not +353. This guide focuses on the Republic of Ireland.)

Mobile Number Prefixes in Ireland

Irish mobile phone numbers generally begin with ’08’ followed by another digit, such as ‘085’, ‘086’, ‘087’, ‘089’. Similar to landline area codes, you must drop the leading ‘0’ when dialing from outside Ireland.

Example Mobile Prefixes:

  • 083: Dial as 83
  • 085: Dial as 85
  • 086: Dial as 86
  • 087: Dial as 87
  • 089: Dial as 89

Understanding these specific codes is vital for successful international calls to Ireland. Always double-check the area code or mobile prefix for the number you are trying to reach.


Putting It All Together: The Phone Number Format

Now that you know the components, let’s see how an entire Irish phone number looks when you dial it from the USA. Proper phone number format is crucial for your call to connect.

Standard Format for Calling Irish Landlines

For landline numbers, the sequence is:

USA Exit Code (011 or +) + Ireland Country Code (353) + Irish Area Code (without 0) + Local Phone Number

Example: If you want to call a Dublin landline with the number (01) 123 4567:

  • From a Landline: 011 353 1 123 4567
  • From a Mobile: +353 1 123 4567

Standard Format for Calling Irish Mobile Phones

For mobile numbers, the sequence is:

USA Exit Code (011 or +) + Ireland Country Code (353) + Irish Mobile Prefix (without 0) + Local Mobile Number

Example: If you want to call an Irish mobile number 087 987 6543:

  • From a Landline: 011 353 87 987 6543
  • From a Mobile: +353 87 987 6543

Quick Reference Table: Ireland Phone Number Formats

Type of CallDialing Format (from USA Landline)Dialing Format (from USA Mobile)Example (Hypothetical Number)
Irish Landline011 353 [Area Code without 0] [Local Number]+353 [Area Code without 0] [Local Number]Dublin: 011 353 1 1234567 or +353 1 1234567
Irish Mobile011 353 [Mobile Prefix without 0] [Local Number]+353 87 9876543 or +353 87 9876543

Always ensure you have the correct and complete number before dialing to avoid any connection issues.


Best Time to Connect: Mind the Time Difference

One of the most crucial aspects of international calls to Ireland is understanding the time difference. Calling at an inconvenient hour can lead to missed connections or interrupted sleep for the person you’re trying to reach.

Ireland’s Time Zone

Ireland observes Irish Standard Time (IST) during the summer months, which is Greenwich Mean Time (GMT+1). During winter, it reverts to GMT. For most of the year, Ireland is 5 hours ahead of Eastern Standard Time (EST) in the USA.

Example:

  • If it’s 10:00 AM EST in New York, it’s 3:00 PM IST in Dublin.
  • If it’s 1:00 PM PST in Los Angeles, it’s 9:00 PM IST in Dublin.

Common US Time Zones and Their Difference from Ireland

Here’s a simple breakdown of the time difference between various US time zones and Ireland:

  • Eastern Standard Time (EST): Ireland is 5 hours ahead.
  • Optimal Calling Window: 10:00 AM – 4:00 PM EST (corresponds to 3:00 PM – 9:00 PM in Ireland, typical evening hours).
  • Central Standard Time (CST): Ireland is 6 hours ahead.
  • Optimal Calling Window: 9:00 AM – 3:00 PM CST (corresponds to 3:00 PM – 9:00 PM in Ireland).
  • Mountain Standard Time (MST): Ireland is 7 hours ahead.
  • Optimal Calling Window: 8:00 AM – 2:00 PM MST (corresponds to 3:00 PM – 9:00 PM in Ireland).
  • Pacific Standard Time (PST): Ireland is 8 hours ahead.
  • Optimal Calling Window: 7:00 AM – 1:00 PM PST (corresponds to 3:00 PM – 9:00 PM in Ireland).

Tips for Scheduling Your Calls

  • Consider Weekends: Weekends might offer more flexibility for both parties, but still be mindful of early mornings or late nights.
  • Check for Daylight Saving Changes: Both the US and Ireland observe Daylight Saving Time, but they may start and end on different dates. This can temporarily change the time difference by an hour. Always check a reliable time zone converter online before making an important call.
  • Communicate in Advance: If possible, send a quick message or email to the person you plan to call to confirm a suitable time. This prevents any inconvenience and ensures a successful connection.

Planning your call around the time difference will make communication much more convenient and effective for everyone involved.


Understanding the Cost of Calling Ireland

The cost of making international calls to Ireland from the USA can vary significantly depending on the service you use. Traditional landline or mobile carriers often charge high per-minute rates, while modern alternatives offer more affordable solutions.

  • Landline Carriers: Traditional phone companies might charge anywhere from $0.05 to $0.50 per minute for international calls to Ireland. These rates can also vary based on whether you’re calling a landline or a mobile number, and if you have an international calling plan. Without a plan, costs can be even higher.
  • Mobile Carriers: Your US mobile carrier might offer international calling packages that reduce per-minute rates. However, if you don’t have such a plan, standard international roaming rates or pay-as-you-go rates can be very expensive, sometimes exceeding $1.00 per minute. These costs can quickly add up during longer conversations.

Hidden Fees: Be aware of potential connection fees, minimum charges, or even higher rates for calling Irish mobile numbers versus landlines. Always check with your specific provider for their detailed international calling rates.

Modern, Cost-Effective Alternatives

The good news is that advancements in technology have made calling Ireland from America much more affordable. Internet-based calling services, known as Voice over Internet Protocol (VoIP) services, are often the cheapest option.

  • VoIP Services: These services route calls over the internet, drastically reducing costs. Many VoIP providers offer:
  • Unlimited International Calling Plans: For a flat monthly fee, you can make unlimited calls to certain countries, including Ireland.
  • Low Per-Minute Rates: If you prefer pay-as-you-go, per-minute rates are typically much lower than traditional carriers, often just a few cents per minute.
  • Virtual Numbers: Some services allow you to purchase a virtual Irish number, making it seem like you’re calling from within Ireland, which can be beneficial for businesses or frequent callers.

Benefits of VoIP: Besides lower costs, VoIP services often provide better call quality (especially with a strong internet connection), and offer additional features like call recording, SMS, and even WhatsApp integration, which traditional carriers don’t always provide.

While traditional methods work, exploring VoIP options is highly recommended for anyone looking to make frequent or long international calls to Ireland without breaking the bank.

Troubleshooting Common Calling Issues

Even with the correct dialing sequence, you might occasionally encounter issues when calling Ireland. Here are some common problems and their potential solutions.

1. Call Not Connecting

  • Double-Check the Number: The most common error is a misdialed digit. Carefully re-enter the entire number, including exit codes and country codes.
  • Omitted ‘0’ for Area/Mobile Code: Remember to drop the leading ‘0’ from Irish landline area codes (e.g., 01 becomes 1) and mobile prefixes (e.g., 087 becomes 87) when dialing from the USA. This is a very frequent mistake.
  • Insufficient Funds/Credit: If you are using a prepaid service or a service that charges per minute, ensure you have enough credit.
  • Network Issues: There might be a temporary issue with your phone provider or the Irish network. Try again after a few minutes, or try calling from a different phone or service.
  • Incorrect Exit Code: Ensure you’re using ‘011’ for landlines or ‘+’ for mobiles as the USA exit code.

2. Poor Call Quality

  • Internet Connection (for VoIP services): If using a VoIP service like Telfon, a weak or unstable internet connection will degrade call quality. Try moving closer to your Wi-Fi router, connecting to a stronger network, or restarting your modem/router.
  • Background Noise: Both on your end and the recipient’s end, excessive background noise can make communication difficult. Move to a quieter environment if possible.
  • Headset Quality: A poor-quality microphone or speaker on your phone or headset can affect clarity.
  • Network Congestion: At peak times, networks can become congested, leading to lower call quality. Try calling at a different time.

3. Voice Mail Only

  • Time Zone Error: You might be calling at an inconvenient time when the person is asleep, at work, or simply unable to answer. Double-check the time difference and try calling during typical waking hours in Ireland.
  • Recipient Busy/Unavailable: The person you’re calling might be on another call, away from their phone, or deliberately not answering.
  • Blocked Number: In rare cases, your number might be blocked by the recipient.

4. High Costs

  • Check Your Plan: If you’re using a traditional carrier, review your international calling plan or lack thereof. Standard rates can be very high.
  • Consider VoIP: For significant savings, switch to a VoIP service like Telfon that offers competitive per-minute rates or unlimited international calling plans.
  • Use Virtual Numbers: If you call frequently for business, a virtual Irish number from Telfon can reduce costs for your Irish contacts calling you.

By systematically troubleshooting these common issues, you can often quickly resolve connection problems and ensure smoother communication when calling Ireland from the USA.


Frequently Asked Questions (FAQs)

Here are some common questions people ask about calling Ireland from the USA, with clear and concise answers.

Q1: What is the international dialing code for Ireland?

A1: The international dialing code for the Republic of Ireland is +353. You will use this after the USA exit code (011) or the ‘+’ symbol.

Q2: Do I need to remove the leading ‘0’ from Irish phone numbers when calling from the USA?

A2: Yes, absolutely. For both Irish landline area codes (e.g., 01 for Dublin) and mobile prefixes (e.g., 087), you must drop the leading ‘0’ when dialing from outside Ireland. So, 01 becomes 1, and 087 becomes 87.

Q3: How many hours ahead is Ireland compared to New York (EST)?

A3: Ireland is typically 5 hours ahead of Eastern Standard Time (EST). If it’s 10:00 AM EST in New York, it’s 3:00 PM in Ireland.

Q4: What is the best time to call Ireland from the USA to avoid disturbing anyone?

A4: Generally, aim to call between 10:00 AM EST and 4:00 PM EST (or equivalent in your US time zone). This typically corresponds to 3:00 PM to 9:00 PM in Ireland, which is a good window for business calls or personal chats in the evening.

Q5: Can I send text messages (SMS) to Ireland from my US mobile phone?

A5: Yes, most US mobile carriers support international SMS. The format for texting is similar to calling: +353 followed by the Irish mobile number (without the leading ‘0’). Services like Telfon also offer SMS capabilities.

Q6: Are calls to Irish mobile numbers more expensive than landlines?

A6: Often, yes. Traditional phone carriers frequently charge higher per-minute rates for calling international mobile numbers compared to landlines. However, VoIP services like Telfon usually offer more uniform and lower rates for both.

Q7: What are the main differences between calling from a landline versus a mobile phone?

A7: The primary difference is the international exit code. For landlines, you dial 011. For mobile phones, you can simply use the ‘+’ symbol before the country code, which automatically acts as the international exit code. Both methods require you to drop the leading ‘0’ from Irish area/mobile codes.

Q8: What if my call to Ireland isn’t connecting?

A8: First, double-check that you have dialed the full number correctly, including the 011 or +, 353, and the Irish number without its leading 0.

Q10: Is Northern Ireland part of the Republic of Ireland for dialing purposes?

A10: No, Northern Ireland is part of the United Kingdom and uses the UK country code +44, not +353. If you’re calling Northern Ireland, the dialing code would be different. This guide focuses on the Republic of Ireland.
