In less than a month, all those flying domestically will only be able to board an airplane if they have a Real ID — that gold star in the upper corner of your driver’s license — or a valid passport.

It’s been 20 years since Congress passed the Real ID Act. It’s been delayed numerous times but is now set to take effect May 7.

If you don’t have one, and you don’t have a valid passport, it’s simple: you won’t be able to fly. With only four weeks remaining, DMV offices are busy getting people signed up.

In West Virginia, the Division of Motor Vehicles offers a couple of options. Those who are ready to hop online to start the process can go to http://go.wv.gov/realidheadstart, though a visit to the DMV is still required. Those who prefer a total in-person experience can be sure of which documents are necessary by checking here before stopping in: https://appengine.egov.com/apps/wv/DMV/RealID.

Ohio’s Bureau of Motor Vehicles also suggests those whose IDs do not expire until after May 7 should consider renewing early. Buckeye State residents can check here: https://www.bmv.ohio.gov/dl-real-id.aspx

Along with not being able to board an airplane, those without a Real ID may not be able to enter some federal facilities.

If your ID does not have a star on it, or if it explicitly says “Not for federal ID,” it’s time to get a new one. Don’t wait until May to do it. Do yourselves, and those working on the other side of the counter, a favor and get this done.
