Dialing Formats
For local calls within the same area code, dial the subscriber number (usually 7 digits) without the area code. For example, to call a landline in San Nicolás from another landline in the same city, dial 442-XXXX (where XXXX is the local number).
For national long-distance calls from other Argentine cities, dial 0-336-XXXXXXX (including the trunk prefix 0). For international calls from abroad, dial +54 336 XXXXXXX (omit the leading 0).
Example: If the local number is 442-1234, the international format is +54 336 442-1234.
Overlays and Numbering Changes
As of 2024, there are no overlay codes for 336; the area code remains exclusive to its geographic region. However, due to the growth of mobile services, some mobile numbers in the area may use the same prefix but are non-geographic. Always verify if the number is a fixed line or mobile, as mobile numbers in Argentina typically start with 15 after the area code when dialed nationally (e.g., 0-336-15-XXXX-XXXX).
Caller Instructions
Local callers: If you are within the 336 area, dial the 7-digit subscriber number directly. For calls to mobile phones from a fixed line, you may need to dial the full national format.
International callers: Dial your country's exit code, then 54 (Argentina's country code), then 336, followed by the 7-digit local number. For example, from the US/Canada, dial 011 54 336 442-1234.
