You can find your Jetty membership number within the Account Settings section after you log into your account.
Keep in mind that your membership number is different from a plan (or policy) number. Every Jetty Member receives his or her own membership number—think of it like a user ID. Then, for every plan you buy, you'll receive a unique plan ID related to each specific plan purchased.
So, as an individual Jetty Member (i.e., for any given membership number), you could have zero, one or multiple plan (or policy) IDs, depending on how many plans you purchased with us.
