Quick usage in different languages

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

JavaScript: /^[A-Z0-9]{13,15}$/.test(value)
Python: re.match(r"^[A-Z0-9]{13,15}$", value)
Java: Pattern.compile("^[A-Z0-9]{13,15}$").matcher(value).matches()
C# / .NET: Regex.IsMatch(value, @"^[A-Z0-9]{13,15}$")
Go: regexp.MustCompile(`^[A-Z0-9]{13,15}$`).MatchString(value)
Ruby: /^[A-Z0-9]{13,15}$/.match?(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.
Uppercase only. Ranges like [A-Z] won't match lowercase. Add a-z (or the i flag) if lowercase input should be accepted.
Validate beyond format. Matching the format doesn't guarantee the value is real. Confirm the puc certificate number against a source of truth (database, API, or checksum) where it matters.
