How to implement KWD safely

Kuwaiti Dinar uses ISO 4217 alpha code KWD and numeric code 414.

KWD appears in the current ISO 4217 list published 2026-01-01. KWD has ISO minor unit 3, so one major unit divides into 1000 minor units. Configure Intl.NumberFormat with currency: "KWD"; do not hardcode the symbol or assume every currency uses two decimals.

د.ك is the reference symbol in this dataset. Store KWD 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 KWD with 1 countries or territories (KW). 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 KWD formatting
new Intl.NumberFormat('en-US', {
  style: 'currency',
  currency: 'KWD',
}).format(1234.56);
// → "KWD 1,234.560"

// Minimum/maximum fraction digits
new Intl.NumberFormat('en-US', {
  style: 'currency',
  currency: 'KWD',
  minimumFractionDigits: 3,
  maximumFractionDigits: 3,
}).format(99);
// Example display precision: 3 decimal places
// ISO 4217 minor unit: 3

// Integer minor-unit storage
// KWD amount = value × 1000
