Find any 387- phone number in Ontario

The 387 area code is a telephone numbering plan area code assigned by the North American Numbering Plan to the province of Ontario. This area code was created in 2020 through an overlay plan designed to meet the growing demand for phone numbers. The 387 area code covers the Ajax, Brampton, Caledon, Pickering, and part of Toronto, although there are several local exceptions. The first three-digit digits of 387 are shared with area code 905, however other numbers with the 905 prefix may be switched to the 387 area code over time.

The North American Numbering Plan is the system that designates area codes and is administered by Neustar, formerly known as the Numbering Plan Administration. This system allows for the routing of calls placed from one area code to another, giving flexibility to people making long-distance or international phone calls. Neustar continually monitors the demand for phone numbers throughout North America and designs plans such as the 387 overlay to ensure each area has the capacity necessary for new citizens and businesses to make and receive phone calls.
