From the Costa Rica Tourism Board:
Passengers coming from the U.S. must show through their driverβs license or state identification (State ID) that they live in one of the authorized states. This requirement excludes children travelling with their family. This requirement will be necessary until Nov. 1.
Note that drivers' licenses are issued by the individual states in the US, not by any sort of federal agency, and they generally list the holder's home address.
After November 1, all US citizens & residents will be welcome to Costa Rica regardless of their place of residence.
