Area code 185 is not assigned to any region in North America. In fact, there is no area code 185 in the North American Numbering Plan (NANP). The NANP includes area codes ranging from 201 to 999, but 185 is not among them.
It’s possible that the number 185 is being confused with a country calling code. For example, China uses the country calling code +86, and within China, mobile phone numbers often start with prefixes like 185, 186, or 187, which are assigned to specific mobile carriers.
