New York City has grown so much that like other big cities, availability of numbers in the original 212 area code is depleted. There are a number of alternative area codes that were overlaid on top to meet demand. These are 917, 646 and 332.
332 is the latest area code for NYC and was introduced in June 2017. (more info: CNN) If you really need a 212 number, reach out and we'll try and find one. You can also keep searching in Talkdesk on the add numbers page as they will periodically reappear as numbers are recycled. As there are no new numbers in 212, whichever number you get will have previously been used before. You might prefer to have a new 332 instead. You'll likely be the first to own it!
