Why the Confusion About a “USA 3 Digit Country Code”?
While the correct code is straightforward (+1), the idea of a “usa 3 digit country code” persists online for several reasons:
- Confusion with ISO Codes: Some international standards, like ISO 3166-1 numeric, use three-digit codes *for identifying countries in databases* (the US is 840), but these are **NOT** used for dialing phone numbers.
- Confusion with Area Codes: US phone numbers use a 3-digit **area code** *after* the +1 country code to specify a region (e.g., +1-212-xxx-xxxx for New York City). People might mistakenly think this area code is the country code.
- Incorrect Information Online: Misleading websites or outdated data sometimes incorrectly list or imply a 3-digit code.
- Other Countries’ Codes: Some other countries *do* use 3-digit country codes, which might add to the confusion.
