What is 332 area code?

The 332 area code is an overlay for the boroughs of New York City, specifically serving Manhattan. It was introduced in June 2017 to provide additional numbering options due to the exhaustion of numbers from existing area codes, such as 212, 646, and 917. Overlay area codes like 332 mean that multiple area codes can cover the same geographic area, allowing for more phone numbers without splitting the region geographically. People in the area must dial all 10 digits of a phone number even for local calls. This change was implemented to accommodate the high demand for new phone numbers in the densely populated and highly connected area of Manhattan.
