Major Components of Argentina’s Phone Number
The Argentine phone number format includes the country code, trunk code, area code/mobile prefix, and the local phone number. Each component plays a unique role in ensuring the call connects accurately.
1. Country Code
The country code is a crucial element of the international phone number formats. It directs your call to the right country when calling internationally. Without this, your call won’t route correctly to your target country. For Argentina, the country code is +54.
2. Trunk Code
The Argentine phone number format includes the trunk code ‘0 ' before the area code when making a domestic call within the country. However, it is not applied to international calls. The country code replaces it when calling Argentina from overseas.
3. Area Code
The area code identifies the specific geographical region within the country. Argentina has 25 area codes, and they are typically 2 to 4 digits long. You must include these codes to route your calls to a specific region in Argentina, whether dialing locally or internationally.

4. Mobile Prefix
In Argentina, mobile numbers include a specific prefix ‘15’ after the area code when dialed domestically. This prefix helps identify the number as a mobile line within the country. However, when calling an Argentine mobile number from abroad, this ‘15’ is not used. Instead, it is replaced by the digit ‘9’.
5. Subscriber’s Number
The subscriber’s number is the unique phone number assigned to a specific individual or business line. It is the final part of any phone number. Subscriber numbers in Argentina typically consist of 6 to 8 digits. The total number of digits varies depending on the length of the area code.

Common Mistakes When Calling Argentina from Abroad & How to Avoid Them
When dialing Argentina, avoid using the trunk code ‘0’ for international calls and correctly use the mobile prefix for local and international calls. Also, consider the time difference between your country and Argentina, to ensure your call reaches the right time for your receiver.
- Including the Trunk Code ‘0’: The trunk code ‘0’ is used only for domestic calls within Argentina. When dialing from abroad, you should omit the trunk code; otherwise, the call will fail or may route to the wrong destination.
- Keeping the Domestic Mobile Prefix ‘15’: The ‘15’ prefix is used for mobile calls within Argentina, but should not be included for overseas calls. Instead, you must replace it with the international mobile prefix ‘9’ after the country code.
- Missing the International Exit Code: Most of the time, phone numbers are written without the international exit code. That’s why many people forget to include the exit code even when dialing internationally. You must include the exit code whenever placing calls outside of your country.
- Ignoring Time Zone Differences: Argentina is in a different time zone from many other countries. Be mindful of the time difference when dialing to avoid calling at inconvenient hours. For this, it’s recommended to check the current local time in Argentina before placing your call.
