Some Mathematica packages contain wording at the bottom of the box that states: “Not for Export; U.S. and Canada Use Only.” International licenses for use outside the U.S. and Canada may be purchased from a Mathematica distributor or directly from Wolfram Research, Inc.

Customers who have already purchased a U.S. and Canada license but are moving out of the country should contact Wolfram Research for options. International license transfers are available for permanent relocation. Customers who need to use Mathematica while traveling may inquire about internationalized passwords if they will be abroad for less than six months before returning to the U.S. or Canada.
