Dear All Banks,

Here is code for your website, so that you can parse numbers, like SSNs, EINs, Telephone #s, etc. entered by your customers instead of locking them out of their online account when they don't read the mostly invisible text on your page that tells them not to enter any dashes, because every other time in their entire life they write them with dashes.
