Where is Area Code 624?
Area code 624 is located in western New York and serves as an overlay for the historic 716 area code. This area code covers several major cities and communities, including Buffalo, Cheektowaga, Tonawanda, and Niagara Falls. As an overlay, 624 was introduced to provide additional phone number capacity for the rapidly growing region, and it serves the same geographic area as 716.
What Time Zone is 624 Area Code in the USA?
Area code 624 operates within the Eastern Time Zone (ET). This means all communities within the area, including Buffalo, Cheektowaga, Tonawanda, and Niagara Falls, observe Eastern Standard Time (EST) during the winter months and Eastern Daylight Time (EDT) during daylight saving time, in alignment with New York State regulations.
History of the 624 Area Code
Area code 716 is one of the original area codes established in 1947, serving western New York for decades. Due to increasing demand for new phone numbers—driven by population growth, new businesses, and the rise of mobile and internet-connected devices—the supply of available 716 numbers began to run low.
To address this, area code 624 was introduced as an overlay rather than splitting the region geographically. This means current residents and businesses kept their 716 numbers, while newly issued numbers may have the 624 prefix. Overlaying allows for a seamless transition and ensures continued access to vital telephone services without requiring number changes for current users. Ten-digit dialing is now required for all local calls within the 716/624 area.
How Many People Use the 624 Area Code?
The 624 area code, as a new overlay, is in the early stages of being assigned to new phone numbers in western New York. The area it serves—together with the 716 code—covers more than one million residents, especially in the cities of Buffalo and Niagara Falls. As demand increases, more residents and businesses will receive numbers with the 624 area code alongside the legacy 716 code.
Is the 624 Area Code Toll-Free?
No, area code 624 is not a toll-free area code. It is a standard geographic area code assigned to western New York. Calls placed to numbers with the 624 area code are charged according to the caller’s phone plan and carrier guidelines, just like calls to or from area code 716.
Toll-free area codes in the United States include 800, 833, 844, 855, 866, 877, and 888.
