There is no area code 139 in North America. Here’s a detailed explanation:
1. Structure of North American Area Codes:
North America uses the North American Numbering Plan (NANP) for telephone numbering.
Under this system:
Area codes are three digits.
The first digit must be between 2 and 9.
The second and third digits can range from 0 to 9.
Therefore, area codes cannot begin with 1 because this is reserved for special dialing purposes (e.g., 1 is the prefix for long-distance calls).
2. Why Area Code 139 Doesn’t Exist:
Since area codes in the NANP cannot start with “1”, there cannot be an area code 139 in North America.
3. If You Encounter “139”:
If you come across a number starting with “139,” it might not be an area code. Instead:
It could be part of an international phone number.
For example, in China, many mobile phone numbers begin with “139.”
Conclusion:
Area code 139 does not exist in North America. If you’re trying to identify the origin of a number starting with “139,” it’s likely international, and additional digits would clarify its location.
