NEWARK, N.J. - July 19, 2000 - IDT Corporation (NASDAQ: IDTC) today announced that IDT Europe, its European telecom subsidiary, is expanding its highly successful "Unity Card" into four new European markets, as the Company continues its rapid growth in the retail telecom sector.

Starting this month, IDT Europe's Unity card, the Company's flagship pan-European calling card product, will be launched in four additional countries - Belgium, Ireland, Sweden and Spain. With this geographic expansion, IDT's prepaid phone cards will be available in nine European countries.

"This product expansion is confirmation of IDT Europe's growing strength and visibility in the European marketplace," said Yoav Krill, Managing Director for Europe.
