If you live in Texas, it's easy. Go to the Dept of Motor Vehicles website, which has a link for "Donate Life Texas". You go to their website and UNLIST yourself as a donor.

The first step to removing your name from the registry is to either go on your state's DMV website or else call them to find out who manages the state’s donor registry. If you just want to do a quick search, most states' registries are shown on the U.S. Department of Health & Human Services’ site organdonor.gov.

In the state of Washington, LifeCenter Northwest manages the donor list. In Oklahoma, the organ donor registry is maintained by LifeShare Transplant. In Mississippi, the Mississippi Organ Recovery Agency, also known as Donate Life Mississippi, oversees the list.

You may be able to go to the organ donor registry site online, create a profile and un-designate yourself as an organ donor or limit which organs you will allow to be donated. This new record replaces any previous record, even if the donor symbol is still on your license. If you do not see a way to do this online, call the donor registry organization.

Good luck. Remember that, just because you remove yourself from a registry doesn't always mean that everyone gets the message. It might not hurt to print "NOT AN ORGAN DONOR, WILL SUE!!!" on a small piece of paper, then use polyurethane to laminate it to the back of your drivers license (not over the scan strip). :>)
