Notes & gotchas

Accepts ₹ symbol, Rs., or INR prefix (or no prefix). The Indian numbering format uses comma after the first 3 digits, then every 2 digits (e.g., 1,00,00,000 = 1 crore). Decimals optional.

Token-by-token breakdown

Every part of the pattern, left to right:

Token	Meaning
`^`	start of string (or line in multiline mode)
`(`	start of a capturing group
`₹`	literal text “₹”
`\|`	OR — try the alternative
`Rs`	literal text “Rs”
`\.?`	optional (zero or one): literal “.”
`\s?`	optional (zero or one): whitespace
`\|`	OR — try the alternative
`INR`	literal text “INR”
`\s?`	optional (zero or one): whitespace
`)?`	end of group, optional (zero or one)
`\d{1,3}`	between 1 and 3 times: digit (0–9)
`(`	start of a capturing group
`,`	literal text “,”
`\d{2,3}`	between 2 and 3 times: digit (0–9)
`)*`	end of group, zero or more
`(`	start of a capturing group
`\.`	literal “.”
`\d{1,2}`	between 1 and 2 times: digit (0–9)

About this pattern

India-specific identifiers are governed by various authorities (UIDAI for Aadhaar, Income Tax Dept for PAN, RBI for IFSC, GSTN for GSTIN, etc.). Regex confirms format; for definitive validation, integrate with the issuing authority's verification API.

Quick usage in different languages

This exact pattern — with the correct escaping and idioms for each language:

JavaScript: /^(₹|Rs\.?\s?|INR\s?)?\d{1,3}(,\d{2,3})*(\.\d{1,2})?$/.test(value)
Python: re.match(r"^(₹|Rs\.?\s?|INR\s?)?\d{1,3}(,\d{2,3})*(\.\d{1,2})?$", value)
Java: Pattern.compile("^(₹|Rs\\.?\\s?|INR\\s?)?\\d{1,3}(,\\d{2,3})*(\\.\\d{1,2})?$").matcher(value).matches()
C# / .NET: Regex.IsMatch(value, @"^(₹|Rs\.?\s?|INR\s?)?\d{1,3}(,\d{2,3})*(\.\d{1,2})?$")
Go: regexp.MustCompile(`^(₹|Rs\.?\s?|INR\s?)?\d{1,3}(,\d{2,3})*(\.\d{1,2})?$`).MatchString(value)
Ruby: /^(₹|Rs\.?\s?|INR\s?)?\d{1,3}(,\d{2,3})*(\.\d{1,2})?$/.match?(value)
PHP: preg_match('~^(₹|Rs\.?\s?|INR\s?)?\d{1,3}(,\d{2,3})*(\.\d{1,2})?$~', $value)

The explainer’s Code tab regenerates these for any pattern you paste, and the downloadable cheat sheet bundles the breakdown, all seven snippets, and the pitfalls below onto one printable page.

Common pitfalls

Anchored to the whole string. This pattern uses ^ and $, so it requires the entire input to match. To find it inside a longer text, drop the anchors and use the global (g) flag.
Escape it correctly per language. In Java and JavaScript strings each backslash must be doubled (\\d); in Python, Go, and C# use raw/verbatim strings so the backslashes survive.
Validate beyond format. Matching the format doesn't guarantee the value is real. Confirm the indian rupee amount against a source of truth (database, API, or checksum) where it matters.
