There are two possibilities:
Depending on what you mean by "the area code of a call," it's either the area code of the phone you're calling from or the area code of the phone you're ringing. The fact that the call is "collect" (reverse charges) is irrelevant.
Of course, without it they can't call back.
+1 (area code) (phone number)
001 + code area + phone
dial 1 and the area code
re- recall
There is no area code 278 in North America (USA, Canada, etc.).
look up the first part of there area code for the number and CALL :)
how can I phone call from India to medellin(area code 4),Colombia(country code57)and phone no.3360484
The point of a phone number is that it uniquely identifies the phone you wish to call. When you dial an area code, you are asking the system to connect you to that area code. So, you would dial the area code of the location you are calling TO.
First, dial 00, then the country code (1), and then the area code and phone number.
Absolutely. Just call the area code and the subscribers number.
