Every Dollar Currency in the World: USD, AUD, CAD, and 20+ More
When someone says "dollar", they usually mean the US Dollar. But over 20 countries have currencies named "dollar", spanning every inhabited continent. If you build multi-currency applications, you need to handle these correctly -- they have different ISO 4217 codes, symbols, and exchange rates despite sharing a name.
This guide lists every dollar currency with its ISO code, the countries that use it, and code examples for working with them programmatically.

By Region
North America and Caribbean
The US Dollar (USD) dominates this region. Beyond the United States, it is the official currency in:
- Ecuador -- fully dollarized since 2000 after abandoning the Sucre
- El Salvador -- dollarized since 2001 (also accepts Bitcoin as legal tender)
- Panama -- uses USD alongside the Balboa (PAB), which is pegged 1:1
The East Caribbean Dollar (XCD) serves 8 island nations and territories, managed by the Eastern Caribbean Central Bank.
The Canadian Dollar (CAD) is the 6th most traded currency globally and is heavily correlated with commodity prices, especially oil.
Asia-Pacific
The Australian Dollar (AUD) is used by Australia and three Pacific island nations (Kiribati, Nauru, Tuvalu). It is the 5th most traded currency globally.
The Singapore Dollar (SGD) and Brunei Dollar (BND) are interchangeable at par through a Currency Interchangeability Agreement since 1967.
The Hong Kong Dollar (HKD) is pegged to the USD through a linked exchange rate system, trading in a narrow band of 7.75-7.85 HKD per USD.
The New Taiwan Dollar (TWD) is the currency of Taiwan and uses the ISO code TWD (not NTD, despite the common NT$ symbol).
Africa
The Namibian Dollar (NAD) is pegged 1:1 to the South African Rand (ZAR), and both currencies circulate freely in Namibia.
The Liberian Dollar (LRD) circulates alongside the US Dollar, which is also widely used in daily transactions.
The Zimbabwe Dollar (ZWL) was reintroduced in 2019 after years of hyperinflation and multicurrency use. USD and other currencies still circulate widely.
South America
The Guyanese Dollar (GYD) and Surinamese Dollar (SRD) are the two South American dollar currencies. Both are relatively low-value compared to USD.
Oceania
The Fijian Dollar (FJD), Solomon Islands Dollar (SBD), and New Zealand Dollar (NZD) serve the Pacific region. NZD is also used by several smaller Pacific territories.
Working with Dollar Currencies in Code
import { currency } from '@koshmoney/countries/currency';
import { country } from '@koshmoney/countries';
// Look up any dollar currency
currency.getCurrency('AU'); // { code: 'AUD', symbol: 'A$', name: 'Australian Dollar' }
currency.getCurrency('SG'); // { code: 'SGD', symbol: 'S$', name: 'Singapore Dollar' }
currency.getCurrency('JM'); // { code: 'JMD', symbol: 'J$', name: 'Jamaican Dollar' }
// Find all countries using a specific dollar
currency.getCountriesByCurrency('NZD');
// ['CK', 'NU', 'NZ', 'PN', 'TK']
// Find all countries using USD
currency.getCountriesByCurrency('USD');
// ['AS', 'BQ', 'EC', 'FM', 'GU', 'IO', 'MH', 'MP', 'PA', 'PR', 'PW', 'SV',
// 'TC', 'TL', 'UM', 'US', 'VG', 'VI']Common Pitfalls
Assuming $ means USD. The $ symbol is used by most dollar currencies. Always use the ISO code (USD, AUD, CAD) to identify currencies unambiguously. Never store or transmit amounts with just a $ symbol.
Confusing currency names with values. A "dollar" in Suriname (SRD) is worth far less than a dollar in the US (USD) or Singapore (SGD). Currency name similarity has no bearing on exchange rates.
Mixing up pegged and independent currencies. Some dollars are pegged (HKD to USD, NAD to ZAR, BND to SGD), meaning their exchange rate is fixed. Others float freely (AUD, CAD, NZD).
Summary
Over 20 currencies worldwide use the name "dollar", each with its own ISO 4217 code and independent (or pegged) exchange rate. The US Dollar is by far the most dominant, serving as both the currency of 18 territories and the world's primary reserve currency. When building financial applications, always use ISO currency codes rather than currency names to avoid ambiguity.
