I saw a position on Craigslist that I would like to apply for. However, they asked to fax resume and copy of your license. Being that this is just a random ad on Craigslist and I have no idea of the name of the organization. Would this be OK? I'm worried about identity theft. I've read not to put my license # on my resume for that reason so I'm hesitant to fax my license to an unknown place.
