How to implement XDR safely

SDR (Special Drawing Right) uses ISO 4217 alpha code XDR and numeric code 960.

XDR appears in the current ISO 4217 list published 2026-01-01. ISO 4217 does not assign XDR a minor unit. The 2-digit precision used in examples is a display choice, not an ISO storage scale. Configure Intl.NumberFormat with currency: "XDR"; do not hardcode the symbol or assume every currency uses two decimals.

SDR is the reference symbol in this dataset. Store XDR 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.

XDR is a supranational or special-purpose unit and has no single country assignment in this directory. 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 XDR formatting
new Intl.NumberFormat('en-US', {
  style: 'currency',
  currency: 'XDR',
}).format(1234.56);
// → "XDR 1,234.56"

// Minimum/maximum fraction digits
new Intl.NumberFormat('en-US', {
  style: 'currency',
  currency: 'XDR',
  minimumFractionDigits: 2,
  maximumFractionDigits: 2,
}).format(99);
// Example display precision: 2 decimal places
// ISO 4217 minor unit: not applicable

// ISO 4217 defines no integer storage scale for XDR.
// Choose and document product-specific precision.
