The country code 120 is not assigned to any specific country or region within the global telecommunication numbering plan.
Understanding International Dialing Codes
International country codes are standardized numerical prefixes essential for routing phone calls to different countries and administrative regions around the world. These codes are primarily governed by the International Telecommunication Union (ITU), which sets guidelines and assigns these unique numbers to ensure seamless global communication.
The Structure of +1 Country Codes
Many countries and territories, primarily in North America and the Caribbean, share the overarching country code +1. This system is known as the North American Numbering Plan (NANP). Within this comprehensive plan, additional digits following the +1 are used to designate specific countries or regions.
For example, country codes are assigned following a format where +1 is succeeded by additional digits. While these additional digits typically form a three-digit Numbering Plan Area (NPA) code (e.g., +1-242), the fundamental structure conceptually uses +1 followed by unique numerical sequences. The specific sequence +120 does not currently correspond to any recognized or assigned country or regional entity within the NANP. This means no active telecommunication area utilizes +120 as its dialing prefix.
Examples of +1 Codes Assigned to Countries and Regions
To illustrate how regions are assigned codes within the +1 system, here are some examples of actual +1 country and regional codes:
| Country/Region | Assigned +1 Code |
|---|---|
| United States | +1 (various NPAs) |
| Canada | +1 (various NPAs) |
| The Bahamas | +1-242 |
| Barbados | +1-246 |
| Bermuda | +1-441 |
| Cayman Islands | +1-345 |
| Dominican Republic | +1-809, +1-829, +1-849 |
| Jamaica | +1-876 |
| Trinidad and Tobago | +1-868 |
| Turks and Caicos Islands | +1-649 |
| United States Virgin Islands | +1-340 |
As demonstrated by these examples, while +1 is the core country code, specific two or three-digit codes after the 1 are allocated to distinguish between different countries or regions participating in the NANP. The number 120 remains unassigned in this sequence.
