AUD — Australian Dollar
fiatHow to implement AUD safely
Australian Dollar uses ISO 4217 alpha code AUD and numeric code 036.
AUD appears in the current ISO 4217 list published 2026-01-01. AUD has ISO minor unit 2, so one major unit divides into 100 minor units. Configure Intl.NumberFormat with currency: "AUD"; do not hardcode the symbol or assume every currency uses two decimals.
A$ is the disambiguated symbol used by this directory, while $ is common in the currency's home market. Store AUD alongside the amount so exports, payments, and accounting data remain unambiguous. Format for display only after choosing the user's locale, because symbol placement and separators belong to the locale rather than the currency record.
This site's coverage associates AUD with 7 countries or territories (AU, CX, CC, NR, NF, TV, KI). Region and language still need separate locale selection; the currency code alone does not choose punctuation or digit shapes. The record was checked against the SIX ISO 4217 source on 2026-07-19; recheck status-sensitive records when the Maintenance Agency publishes a new list.

Intl.NumberFormat
// Basic AUD formatting
new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'AUD',
}).format(1234.56);
// → "A$1,234.56"
// Minimum/maximum fraction digits
new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'AUD',
minimumFractionDigits: 2,
maximumFractionDigits: 2,
}).format(99);
// Example display precision: 2 decimal places
// ISO 4217 minor unit: 2
// Integer minor-unit storage
// AUD amount = value × 100Countries Using AUD
