Washington Department of Fish and Wildlife.
Operators of watercraft not registered in Washington State, seaplanes, and commercial transporters of specified vessel types must purchase aquatic invasive species (AIS) prevention permits to help prevent the spread of AIS in Washington. AIS prevention permits are valid for one year and can be purchased online
(under the "Other" Product Categories tab) or from any of the department's authorized license dealers
. When purchasing online, you may select a preferred activation date. The permit will be valid for one year from that date.
