How to implement LKR safely

Sri Lanka Rupee uses ISO 4217 alpha code LKR and numeric code 144.

LKR appears in the current ISO 4217 list published 2026-09-17. LKR has ISO minor unit 2, so one major unit divides into 100 minor units. Configure Intl.NumberFormat with currency: "LKR"; do not hardcode the symbol or assume every currency uses two decimals.

Rs. is the disambiguated symbol used by this directory, while ₨ is common in the currency's home market. Store LKR 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 LKR with one country or territory: LK. 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.

Common mistakes with LKR

  • Rs. is also a symbol of NPR in this directory. Always pair it with the code LKR or a disambiguated symbol.
  • ₨ is also a symbol of PKR in this directory. Always pair it with the code LKR or a disambiguated symbol.
  • This directory uses Rs. to disambiguate; ₨ is the home-market symbol.

Formatting Examples

Valueen-US
1LKR 1.00
9.99LKR 9.99
100LKR 100.00
1234.56LKR 1,234.56

Intl.NumberFormat

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

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

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