Area code 808 is Hawaii. Area code 301 is in Maryland. Unless you have nationwide long distance included in your calling plan, there will be a charge for that call.
Area code 647 is one of the area codes for the city of Toronto. On most calling plans, that is long distance from Longueuil, Québec.
It depends on your long-distance company and calling plan. Area code 203 is in Connecticut, and area code 507 is in Minnesota.
The International Dialing Code for Italy is 39. There may be an additional code for the city or area for which you're calling. Depending on your long distance carrier, generally the procedure to call internationally is 011 (International Long Distance) 39 (for Italy, or whatever country code you're calling) city or area code you're calling telephone number
It depends on your long-distance company and the specific calling plan you signed up for.
If you are calling a different area code, yes, of course - otherwise how will the system know you are trying to call a number in that area rather than your own?
Area code 340 is the U.S. Virgin Islands. It is thus a domestic call, and should be included if you have unlimited nationwide long distance calling.
It depends on your long-distance company and the particular calling plan you have.
Area code 575 is most of the state of New Mexico, except the northwest part. Area code 915 is El Paso, Texas. The cost to call from 915 to 575 depends on which long-distance company you use, what calling plan you have, and where in 575 you're calling (if the rates are sensitive to distance).
It depends whether the call is local or long distance, which is a different question from whether it is in the same area code or a different area code, unless you're in Mexico. (In Mexico, your area code is exactly the same as your local calling area.) For example, from San Francisco, California, in area code 415, there are local numbers in area codes 415, 650, and 510, but there are also long-distance numbers in area code 415.To make it even more complicated, a "short-distance" call (long distance, but carried by your local phone company) may cost more than a coast-to-coast long-distance call. A call from San Francisco to Eureka, CA, on Pacific Bell will cost more than a call from SF to New York.Bottom line: it depends.
That depends on where you're calling from and what calling plan you have. In North America, area code 212 is for the borough of Manhattan in New York City. It's an ordinary area code, not a toll-free code, but if you are within the local calling area or if your calling plan includes nationwide long distance, you won't pay a toll charge for the call, although you may use "message units."
Area code 876 is Jamaica in the Caribbean. The cost depends on your long-distance carrier and calling plan, but it is an international call even though you dial it "one-plus."
