The easiest thing to provide for proof of insurance is to show a Certificate Of Insurance (COI). It a one-page form that basically gives all the same data with today's date on it. That shows that your policy is still active and not canceled (for non-payment of premium). I reviewed the aMMP program that allnurses has in place and it provides this COI that can be printed or forwarded as a pdf - quick and easy. https://allnurses.com/medical-malpractice-insurance/
