Email Address Regex

A practical check that text looks like an email address: a name, an @, a domain and a top-level domain of two or more letters.

/^[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,}$/

Piece by piece

1. ^the start of the text
2. [A-Za-z0-9._%+-]+one of A–Z, a–z, 0–9, “.”, “_”, “%”, “+”, “-”, repeated 1 or more times, as many as possible
3. @the character “@”
4. [A-Za-z0-9.-]+one of A–Z, a–z, 0–9, “.”, “-”, repeated 1 or more times, as many as possible
5. \.the character “.”
6. [A-Za-z]{2,}one of A–Z, a–z, repeated 2 or more times, as many as possible
7. $the end of the text

Examples

• It doesn't accept every address the standard allows (quoted names, IP-address domains, non-Latin domains).
• Matching the shape doesn't prove the mailbox exists; only sending an email does.
