Regular Expression Details

Title Test Find US ZIP (5 or 5+4)
Expression
^\d{5}$|^\d{5}-\d{4}$
Description
This regular expression will match either a 5 digit ZIP code or a ZIP+4 code formatted as 5 digits, a hyphen, and another 4 digits. Other than that, this is just a really really long description of a regular expression that I'm using to test how my front page will look in the case where very long expression descriptions are used.
