The Ecuadorian peso, also referred to as the Ecuadorian sucre, was the official currency of Ecuador until the country adopted the US dollar in 2000. However, the term "Ecuadorian peso" may still be used colloquially by some individuals. Other synonyms for the Ecuadorian peso include the Ecuadorian currency, Ecuadorian money, and Ecuadorian notes. Additionally, the term "sucre" may still be used in some instances, as it was the official name of the Ecuadorian currency before its replacement with the US dollar. Regardless of the terminology used, it is important to note that the US dollar is the current official currency of Ecuador.
