There are three different kinds of public phones depending upon the type of call being made. Phones for making international calls are bright yellow. Phones for local calls and domestic, long distance calls can be a variety of colors. Look at the signs on the phone to determine the type. International phones take a special phone card available at post offices and convenience stores. Phones for local calls and domestic, long distance take either coins or cards. Phone numbers have 3-digit area codes, plus 7-digit local numbers in the form 123-4567. Within the local calling area, it is not necessary to dial the 3-digit area code.
