Is 423 a country code?

No. 423 is a US area code (a domestic 3-digit code), not a country code. The country (calling) code for the United States is +1, shared across the North American Numbering Plan. So a full 423 number written for international dialing looks like +1 423 followed by the 7-digit local number.
