(B) The appropriate State or local election official shall establish a free access system (such as a toll-free telephone number or an Internet website) that any individual who casts a provisional ballot may access to discover whether the vote of that individual was counted, and, if the vote was not counted, the reason that the vote was not counted.
States described in section 1973gg–2 (b) of this title may meet the requirements of this subsection using voter registration procedures established under applicable State law.
