IR — Iran

Iran is a large Middle Eastern country with a rich Persian cultural heritage spanning thousands of years. Tehran, the capital, is a massive metropolitan area. Iran has significant oil and natural gas reserves and a large, educated population. The Iranian Rial (IRR) has extremely low value, meaning everyday prices are in millions of Rials — Iranians commonly refer to the Toman (1 Toman = 10 Rials) in daily speech. For developers, the IR country code maps to the fa-IR locale for Persian (Farsi), which uses a modified Arabic script with additional characters and RTL text direction. The .ir domain and +98 calling code serve Iran. Iran uses the Solar Hijri calendar (Jalali calendar) as its primary calendar system, requiring robust calendar conversion for international applications. Persian numerals (۰۱۲۳۴۵۶۷۸۹) are used alongside Western Arabic numerals. International sanctions significantly affect Iran's tech ecosystem, requiring compliance checks on IR country codes in financial applications. The Rial's potential redenomination to Toman has been discussed but not yet implemented.
