FIFA did not officially reveal the specific details behind the decision.
Ittihad became the sixth Egyptian club to serve a transfer ban as Zamalek, Modern Sport, Eastern Company, Tala YC, Raya SC and Ismaily are all already banned for different reasons.
Ittiahd was remarkably active in the latest winter transfer window in January; adding five new players into the squad.
The Alexandria-based club currently lie in the 14th place of the league table with 20 points, 23 behind leaders Zamalek.
