License Verification Details

Technical Support - Help desk representatives are available to answer login or registration questions by calling (855) 405-5514 weekdays from 8:00 am to 5:00 pm EST.

Callers may experience extended wait times due to the high number of calls. If you’re unable to wait for a representative, you can leave a call back number.
