  • You could just find a list online e.g. https://greatdata.com/proddata/info/areacodetimezone and build a map of area code to timezone. – Mr. Polywhirl Dec 16 '19 at 12:53
  • It is not possible - in any language. Area codes can cover more than one time zone, and people can take their phone numbers with them when they move to other areas, on both mobile and land-lines. See the linked duplicate for examples. – Matt Johnson-Pint Dec 16 '19 at 15:29

I just grabbed the info from this page and built a look-up map:

https://greatdata.com/proddata/info/areacodetimezone

const timeZoneMap = getTimeZoneMap()
// See: https://stackoverflow.com/a/33561517/1762224
const phoneNumberPattern = /^[+]*[(]{0,1}\d{1,3}[)]{0,1}[-\s\./0-9]*$/g

console.log(timeZoneMap[extractAreaCode('(619) 555-5555')]) // California (PST)

function extractAreaCode(phoneNumber) {
  if (phoneNumberPattern.test(phoneNumber)) {
    return /\d{3}/.exec(phoneNumber)[0] // first three sequential
  }
  return null
}

function getTimeZoneMap() {
  return {
    "201" : { "timezone" : "EST", "state" : "New Jersey" },
