Where area code 416 is used

Numbers in the code are written (416) NXX-XXXX at home and +1 416 NXX-XXXX when dialled from outside Canada and the United States. Since the NANP moved to 10-digit dialling you must always include the area code, even for a local call.
Other area codes in this footprint: 289, 905, 613, 807, 519, 705, 437, 647. They serve towns in the same territory, so a single street can contain numbers from more than one code. That is normal in the NANP and does not change how you dial.
