In an increasingly interconnected world, making international calls has become a routine part of both personal and professional life for many Americans. Whether it’s staying in touch with family abroad, collaborating with international colleagues, or expanding business reach, understanding international dialing codes is essential. One such code, the +37 country code, represents a cluster of nations primarily in Eastern and Central Europe. For an American audience, knowing how to navigate this dialing prefix can unlock a world of communication possibilities.

The Evolution of the +37 Country Code Block
The story of the +37 country code is rooted in the shifting geopolitical landscape of the late 20th century. While the original “+37” code was historically assigned to East Germany, it became obsolete after German reunification. This freed up a valuable block of numbering space. Following the dissolution of the Soviet Union and other significant political changes, several newly independent or re-emerging nations were assigned codes within the +37 country code range.
Today, the +37 country code is not a single code for one nation, but rather a series of distinct country codes starting with “+37”. These include:
- +370 for Lithuania
- +371 for Latvia
- +372 for Estonia
- +373 for Moldova
- +374 for Armenia
- +375 for Belarus
- +376 for Andorra
- +377 for Monaco
- +378 for San Marino
- +379 (reserved for future assignment, often associated with Vatican City numbers that fall under Italy’s +39 code)
Understanding this distinction is crucial, as simply dialing “+37” won’t connect you to a specific country. You need the full three-digit code that follows.
How to Dial the +37 Country Code from the US
For Americans looking to call a number within the +37 country code block, the process is straightforward but requires adherence to the international dialing format.
Dialing from a Landline:
- Dial the U.S. Exit Code (011): This code signals that you are making an international call from the United States.
- Dial the Full Country Code: Next, enter the specific three-digit +37 country code for your desired destination (e.g., 370 for Lithuania, 371 for Latvia, etc.).
- Dial the Local Number: Finally, enter the local phone number, which typically includes an area code specific to that country.
Example (calling Lithuania): 011 + 370 + [Lithuanian Local Number]
Dialing from a Mobile Phone:
Mobile phones offer a slightly simpler method due to the universal “+” sign functionality.
- Press and Hold “0” for the “+” Sign: On most smartphones, pressing and holding the “0” key will automatically generate the “+” symbol. This acts as a universal international access code, automatically recognizing the correct exit code from your location (in this case, the US).
- Dial the Full Country Code: Immediately after the “+”, enter the specific three-digit +37 country code (e.g., 372 for Estonia, 375 for Belarus, etc.).
- Dial the Local Number: Complete the call by entering the local phone number.
Example (calling Estonia): +372 + [Estonian Local Number]

Navigating Time Zones and Calling Rates
Before making your call, especially for business purposes, it’s always a good idea to consider the time difference. The countries utilizing the +37 country code are primarily located in Central and Eastern European time zones, meaning there can be a significant time gap compared to the various U.S. time zones. A quick online search for the current time in the specific country will help you avoid calling at inconvenient hours.
Calling rates to countries within the +37 country code block can vary widely depending on your mobile carrier or landline service provider.
- Standard Rates: Without an international calling plan, per-minute rates can be expensive.
- International Calling Plans: Many carriers offer international calling plans or add-ons that significantly reduce per-minute costs for frequently called countries. If you anticipate making regular calls to any of these nations, investing in such a plan can lead to substantial savings.
- VoIP Services: Voice over Internet Protocol (VoIP) services like Skype, Google Voice, or WhatsApp often provide very competitive rates or even free calls to other users of the same service, requiring only an internet connection. This can be a highly cost-effective alternative for both personal and business communication.
The Significance of the +37 Country Code for Americans
Beyond personal connections, understanding and utilizing the +37 country code has growing importance for American businesses and individuals alike:
- Business Expansion: The nations within the +37 country code block are increasingly active in global trade and technology. For American businesses looking to expand into new markets, collaborate with international partners, or source talent, seamless communication with these countries is vital.
- Tourism and Travel: These countries offer rich cultural experiences and diverse landscapes, attracting American tourists. Knowing how to dial home or reach local contacts while traveling is essential.
- Cultural Exchange and Education: Educational programs and cultural exchanges between the U.S. and these nations are common. Effective communication facilitates these valuable interactions.
- Global Connectivity: In a world where geographical boundaries are less of a barrier, knowing how to connect across different numbering systems promotes overall global literacy and connectivity.
conclusion
the +37 country code is more than just a sequence of digits; it’s a gateway to connecting with a vibrant and diverse part of the world. For an American audience, understanding its composition and proper dialing procedures is a practical skill that enhances both personal connections and professional opportunities in our increasingly globalized society. By mastering these simple steps, you can confidently reach out and bridge the distance, one call at a time.
