Does your listing on the "do not call" list expire after a period of time?

I don’t know where you are from but f you are a inhabitant of the Netherlands your listing does not expire (only when you unlist yourself).

Yes it does, and you have to have a different listing for each phone number. There is also a growing list of people exempt from having to honor the no call list. Mostly politicians and polling companies are exempt.

@rebbel—I am in the United States

@srmorgan Then I think that @WestRiverrat‘s answer may be of more help.
But when it comes to no call listing it would be better to live in Holland ;-)

It used to. You should sign up again. Newly listed numbers never expire.

Someone once told me it expires every ten years. Not sure if that is true.
