The telephone country code +120 is not specifically assigned to a single country. However, it is part of the North American Numbering Plan (NANP), which includes countries like the United States, Canada, and several Caribbean nations. Typically, country codes in the range of +1 to +199 are assigned to countries within the NANP. The country code +1 is followed by an area code, and 120 is likely the beginning of a specific area code under that plan.
If you are receiving a call with this code, it could be an area code starting with 120, which is part of the broader NANP system.
