Each full-time worker is given a 4-digit pin code that gives them access to outside calls both off-calls and international calls. Pin codes are not to be shared with others.
Making a local call: 9 + local digits
Off-island/U.S Mainland: 9 + 1 + area code + local digits + [4-digit pin code] + #
International: 9 + 011 + country code + city code + local digits # + [4-digit pin code] + #
