How North American Numbering Plan (NANP) Phone Numbers Work
In the United States and Canada, all phone numbers adhere to the North American Numbering Plan (NANP) standards governed by the Federal Communications Commission (FCC). A standard US phone number consists of exactly 10 digits structured into three distinct blocks:
- Area Code (3 Digits - AAA): Identifies the regional geographic zone (e.g., 212 for Manhattan NY, 310 for Los Angeles CA). The first digit cannot be 0 or 1.
- Central Office Exchange Code (3 Digits - NXX): Specifies the specific telephone exchange switch within the area code. The first digit (N) must be 2 through 9.
- Subscriber Line Number (4 Digits - XXXX): Identifies the individual phone line assigned to a household or mobile device (0000 through 9999).
