How it works

Validates 10-digit US/Canada phone numbers (NANP) with an optional +1 country code prefix. The area code must start with 2–9, and separators (space, dot, hyphen) between groups are optional. Parentheses around the area code are also optional. It rejects numbers starting with 0 or 1, which are invalid NANP area codes.

Code Usage

JavaScript

const regex = /^(\+1[\s.-]?)?\(?[2-9]\d{2}\)?[\s.-]?\d{3}[\s.-]?\d{4}$/;
regex.test("(555) 123-4567"); // true

Python

import re
pattern = re.compile(r'^(\+1[\s.-]?)?\(?[2-9]\d{2}\)?[\s.-]?\d{3}[\s.-]?\d{4}$')
bool(pattern.match("(555) 123-4567"))  # True

Go

import "regexp"
r := regexp.MustCompile(`^(\+1[\s.-]?)?\(?[2-9]\d{2}\)?[\s.-]?\d{3}[\s.-]?\d{4}$`)
r.MatchString("(555) 123-4567") // true
