# How to use a GregMat Voucher Code

If you've been given a voucher code for a GregMat subscription, you can follow the instructions on this page to redeem it.

|| GregMat voucher codes are provided to students who subscribe to GregMat through an external organization. They are NOT discount codes and cannot be requested by contacting us.

||| You cannot activate a voucher code on a GregMat account with an active subscription. Please wait for your subscription to expire before activating a voucher code.

You need to be logged in to a free GregMat account to redeem a voucher code. Please see [this page](https://help.gregmat.com/en/article/how-do-i-create-a-gregmat-account-1nuq65m/) if you need help creating an account.
