Sierra Leone

Sierra Leone, located in West Africa, is identified in international systems by the ISO 3166-1 codes SL (alpha-2) and SLE (alpha-3). To call a Sierra Leonean number from abroad, dial the calling code +232. The country's official top-level domain (ccTLD) is .sl, used for local website registration. The national currency is the Sierra Leonean leone, abbreviated as SLE under the ISO 4217 standard, which replaced the old SLL code following currency redenomination in 2022. These identifiers are essential for telecommunications routing, establishing local web presence, and conducting financial or commercial transactions within the nation.
