India formatting implementation notes
For India, format numbers with the explicit locale en-IN; the reference value 1234567.89 renders as 12,34,567.89.
India's reference format uses "." as the decimal mark and comma (",") for grouping. The integer uses Indian 3-then-2 grouping, so digits group as lakh/crore values rather than repeating groups of three. Pass "en-IN" directly to Intl.NumberFormat instead of replacing punctuation in a preformatted string.
INR is shown with ₹ immediately before the amount; the same reference value renders as ₹12,34,567.89. The percent sign appears immediately after the amount. Use the ISO currency code for storage and interchange because a visible symbol can be shared by unrelated currencies.
Western 0–9 digits are the page's reference digit system, and the negative pattern is -n. This country is multilingual in software contexts: also test hi-IN, because language selection can change spacing, punctuation, and currency display without changing the region. Validate output with formatToParts() when spacing, signs, or bidirectional literals affect the interface.
- Locale: en-IN
- Decimal and grouping: 12,34,567.89
- Currency: INR → ₹12,34,567.89
- Digits: Western 0–9 digits

What's different here
- The integer uses Indian 3-then-2 grouping (en-US uses repeating groups of three).
- Uses the same number pattern (decimal mark, grouping, symbol and percent placement) as Pakistan and Bangladesh.
- Nearby differences: Singapore (en-SG) uses repeating groups of three instead of Indian 3-then-2 grouping; Japan (ja-JP) uses repeating groups of three instead of Indian 3-then-2 grouping; China (zh-CN) uses repeating groups of three instead of Indian 3-then-2 grouping; Hong Kong (zh-HK) uses repeating groups of three instead of Indian 3-then-2 grouping.
- Currency: INR has ISO minor unit 2.
- With 3-then-2 grouping the reference value renders as 12,34,567.89, so don't reuse a fixed "every three digits" mask.
- Postal address order: name → building → street number + street → district → city + postcode → region → country. See address formats.

Code Examples
// Basic number
new Intl.NumberFormat('en-IN').format(1234567.89)
// → "12,34,567.89"
// Currency
new Intl.NumberFormat('en-IN', {
style: 'currency',
currency: 'INR'
}).format(1234567.89)
// → "₹12,34,567.89"
// Percentage
new Intl.NumberFormat('en-IN', {
style: 'percent',
minimumFractionDigits: 1
}).format(0.125)
// Compact notation
new Intl.NumberFormat('en-IN', {
notation: 'compact'
}).format(1234567)Negative Number Formats
new Intl.NumberFormat('en-IN').format(-1234567.89)new Intl.NumberFormat('en-IN', { style: 'currency', currency: 'INR', currencySign: 'accounting' }).format(-1234567.89)Edge Cases & Notes
CRITICAL: Indian grouping system — rightmost group = 3 digits, then groups of 2. 1,000,000 = 10,00,000 (ten lakh). 10,000,000 = 1,00,00,000 (one crore). Intl.NumberFormat('en-IN') handles this natively.
