I had buy adwords voucher, but not use it now. Can help me, how to check if that voucher valid or not? thanks
You'll have to use it in your AdWords account. I'm going to guess (99.99999999999% likely correct) that nobody here has access to Google validation checking for vouchers...
you cant really check it, got to put it an try it.. but remember there is an expiry date for each voucher
I would say just go to the manage billing tab and go to the bottom and you will see coupon code, just type in the coupon code and it will automatically tell you if it is valid or not.
Make a new account, add it and then sell that account. (btw that's totally against their tos and you'll get banned, but it's an option)
Actually there is a way of verifying if a voucher is valid, you have to do is enter the code into your google adwords account, but DONT activate the account, just at last step click back in your browser, and the voucher will remain active Remember DONT ACTIVATE your account
I have a software which can be used to test Voucher validity in bulk. If you are a bulk seller/buyer, just copy-paste the vouchers into it and run it. it will tell you which all vouchers are valid/not valid or expired. It will separate vouchers of each kind from the others, so that you can know the exact status of your vouchers. Contact me for more details
Just type it in your account. There's really no other way to do this as far as I know. And why wouldn't you want to use it right now? What's the difference if you get billed on clicks from your credit card or from the cash credit that voucher provides to your account?
Its simple. Just enter the coupon code into "redeem coupon" and submit. If you get message at top "coupon already redeemed" then its already used. If you see just error message of First name, last name. Then its means your coupon is ok. I test with this technique.
I know a method of testing. Have a look here: http://www.adwords-vouchers-shop.com/index.php?route=information/information&information_id=6
