Universal international freephone number
From Wikipedia, the free encyclopedia.
A universal international freephone number (UIFN) is a worldwide toll free "800 number" issued by the ITU. Like the 800 area code issued for the NANP in the U.S and Canada, the call is free for the caller, and the receiver pays the charges. UIFN uses ITU country code 800, so that no matter where the caller is, only the international access code (IAC) and the 8-digit UIFN need to be dialed. Currently, about 30 countries participate in the UIFN programme.
