How Many Countries Officially Use the US Dollar as Legal Tender?

Six sovereign countries officially use the US dollar as their national currency. In these countries, the US dollar is the primary and legally recognized medium of exchange for all public and private transactions.
Countries That Use the US Dollar Officially
| Country | Year Adopted | Reason for Adoption |
| United States | 1792 | National currency |
| Panama | 1904 | Monetary stability & trade |

It is important to note that this list refers only to sovereign nations. Some US territories, such as Puerto Rico and Guam, also use the US dollar, but they are not independent countries.
Countries That Use the US Dollar Alongside Their Own Currency
Several countries don’t officially adopt the US dollar as legal tender but allow it to circulate alongside their domestic currency, this practice is called partial dollarization and helps stabilize local economies, facilitate international trade, and provide a trusted medium for transactions.
4 Examples of Partial Dollarization
- Cambodia: US dollars are widely accepted in major cities for retail and real estate, though the Cambodian riel remains official.
- Bahamas: The Bahamian dollar is pegged 1:1 to the US dollar, and both currencies are commonly used.
- Jamaica: US dollars are often accepted in tourism and banking sectors alongside the Jamaican dollar.
- Lebanon: Due to economic instability, US dollars are widely used for savings, loans, and large transactions.
This distinction helps users understand the difference between full dollarization (official use) and informal acceptance, which affects financial policies, currency stability, and trade dynamics.
Why Do Some Countries Use the US Dollar?
Many countries adopt the US dollar either officially or partially to achieve economic stability, control inflation, and facilitate international trade. Using a globally trusted currency like the US dollar reduces the risk of local currency devaluation and increases confidence among investors and citizens.
4 Key Reasons for Dollar Adoption
- Economic Stability: Countries facing volatile currencies often adopt the US dollar to stabilize prices and prevent hyperinflation.
- Trade and Investment Benefits: The US dollar is widely accepted globally, making import-export transactions smoother and more predictable.
- Inflation Control: Dollarization limits a government’s ability to print money excessively, helping control inflation.
- Investor Confidence: Foreign investors are more likely to engage in countries where a strong and stable currency is in use.
Understanding these reasons explains why countries like Ecuador, El Salvador, and Panama officially adopted the US dollar, while others maintain partial dollarization for practical and economic advantages.

Its dominance ensures stability in global markets and makes it the most widely used currency for cross-border transactions.
