They started printing activation codes on their 30915 labels. People using the FREE DYMO/Endicia stamp printing service will be prompted to enter an activation code every 200 labels. If you are using this FREE service, do NOT purchase these labels. All customers with DYMO/Endicia paid subscriptions are NOT IMPACTED by these new security features.
