Our boat did not have the sticker but you are able to purchase the decal when you start using the app since they accept the purchase order number in the certificate number field. Basically, I purchased the decal when I was setting up the boat in the app and it links you to a different site to make the purchase. I expect to receive it in a few weeks. Cost for our decal was something like 28 per year. The site to purchase the decal was not very user friendly and not integrated with the other .Gov sites but the purchase number worked perfectly when I used it on the app. We own the boat but I will share the info with our charter company so other people can use it.
