Iran

Iran, identified by ISO codes IR (alpha-2) and IRN (alpha-3), uses the international calling code +98 for inbound calls and the country-code top-level domain (ccTLD) .ir for web addresses. The national currency is the Iranian rial (IRR), abbreviated IRR in financial and business transactions. These identifiers are essential for international telecommunications, enabling direct dialing to Iranian phone numbers, and for domain registration under .ir, which supports local web presence. In economic contexts, IRR formatting and exchange rates are critical for trade, banking, and e-commerce operations involving Iran, making accurate code usage fundamental for global communication and commerce with the country.
