UYU — Uruguayan Peso
fiatHow to implement UYU safely
Peso Uruguayo uses ISO 4217 alpha code UYU and numeric code 858.
UYU appears in the current ISO 4217 list published 2026-01-01. UYU has ISO minor unit 2, so one major unit divides into 100 minor units. Configure Intl.NumberFormat with currency: "UYU"; do not hardcode the symbol or assume every currency uses two decimals.
$U is the reference symbol in this dataset. Store UYU 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 UYU with 1 countries or territories (UY). 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.

new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'UYU',
}).format(1234.56);
// → "UYU 1,234.56"
// Minimum/maximum fraction digits
new Intl.NumberFormat('en-US', {
style: 'currency',
