Frequently asked questions
Can a regex fully validate an email address?
Not perfectly, because the official rules are very complex. Use a simple pattern for typos, then verify ownership by sending a confirmation email.
Why does a phone regex fail for my number?
Phone formats differ a lot between countries. Choose a pattern for your region or loosen it, and test it with real numbers.
Should I rely on a regex for user input?
Use it as a first check and also validate on the server. A pattern only checks the shape of the text, not that it is real.
