South Africa formatting implementation notes
For South Africa, format numbers with the explicit locale en-ZA; the reference value 1234567.89 renders as 1 234 567,89.
South Africa's reference format uses "," as the decimal mark and a narrow non-breaking space (U+202F) for grouping. The integer uses repeating groups of three digits. Pass "en-ZA" directly to Intl.NumberFormat instead of replacing punctuation in a preformatted string.
ZAR is shown with R immediately before the amount; the same reference value renders as R 1 234 567,89. 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 af-ZA, zu-ZA, 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-ZA
- Decimal and grouping: 1 234 567,89
- Currency: ZAR → R 1 234 567,89
- Digits: Western 0–9 digits

// Basic number
new Intl.NumberFormat('en-ZA').format(1234567.89)
// → "1 234 567,89"
// Currency
new Intl.NumberFormat('en-ZA', {
style: 'currency',
currency: 'ZAR'
}).format(1234567.89)
// → "R 1 234 567,89"
// Percentage
new Intl.NumberFormat('en-ZA', {
style: 'percent',
minimumFractionDigits: 1
}).format(0.125)
// Compact notation
new Intl.NumberFormat('en-ZA', {

}).format(1234567)Negative Number Formats
new Intl.NumberFormat('en-ZA').format(-1234567.89)new Intl.NumberFormat('en-ZA', { style: 'currency', currency: 'ZAR', currencySign: 'accounting' }).format(-1234567.89)Edge Cases & Notes
en-ZA uses comma as decimal — same as European format despite English language.
