How to implement TWD safely

New Taiwan Dollar uses ISO 4217 alpha code TWD and numeric code 901.

TWD appears in the current ISO 4217 list published 2026-01-01. TWD has ISO minor unit 2, so one major unit divides into 100 minor units. Configure Intl.NumberFormat with currency: "TWD"; do not hardcode the symbol or assume every currency uses two decimals.

NT$ is the disambiguated symbol used by this directory, while $ is common in the currency's home market. Store TWD 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 TWD with 1 countries or territories (TW). 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

JavaScript
// Basic TWD formatting
new Intl.NumberFormat('en-US', {
  style: 'currency',
  currency: 'TWD',
}).format(1234.56);
// → "NT$1,234.56"

// Minimum/maximum fraction digits
new Intl.NumberFormat('en-US', {
  style: 'currency',
  currency: 'TWD',
  minimumFractionDigits: 2,
  maximumFractionDigits: 2,
}).format(99);
// Example display precision: 2 decimal places
// ISO 4217 minor unit: 2

// Integer minor-unit storage
// TWD amount = value × 100
