WikiIran has exposed recently how one of Iran's largest money exchange houses, The Tahayyori Guarantee Society (شرکت تضامنی تحیری و شرکاء)/ARZ-IRAN (صرافی ارز ایران), operates an expanded international network of over 60 front companies for money laundering and circumventing the international sanctions against the Islamic Republic. See Part 1 and part 2.

WikiIran is exposing here more information regarding the Iranian banks and companies which had worked with those front companies operated by Tahayyori. Based on a close review of the records from Tahayyori's servers, WikiIran highlights here top-10 of these entities, filtered by their scope of financial activities.

These Iranian banks and companies work through Tahayyori’s network using front companies abroad which operate internationally on their behalf and help them regain access to the international financial system despite sanctions.
