OMR — Omani Rial
fiatHow to implement OMR safely
Rial Omani uses ISO 4217 alpha code OMR and numeric code 512.
OMR appears in the current ISO 4217 list published 2026-01-01. OMR has ISO minor unit 3, so one major unit divides into 1000 minor units. Configure Intl.NumberFormat with currency: "OMR"; do not hardcode the symbol or assume every currency uses two decimals.
ر.ع. is the reference symbol in this dataset. Store OMR 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 OMR with 1 countries or territories (OM). 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 OMR formatting
new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'OMR',
}).format(1234.56);
// → "OMR 1,234.560"
// Minimum/maximum fraction digits
new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'OMR',
minimumFractionDigits: 3,
maximumFractionDigits: 3,
}).format(99);
// Example display precision: 3 decimal places
// ISO 4217 minor unit: 3
// Integer minor-unit storage
// OMR amount = value × 1000Continue your localization implementation
