I see a code with numbers when I active my host and request for voucher ( google adwords voucher ) . So , is it Google adwords voucher ? . Or I have to wait for an email from my hosting service ?
You should probably wait for the e-mail from your hosting service. If you have registered using Godaddy, then they usually e-mail you about the status of your voucher, and typically the voucher is in your Order History page in Godaddy.
