Re: I have a promotional code for $100 that doesn't work
Hello Lisa l,
Welcome to adwords community,
Promotional codes are usually only meant for new advertisers, providing an easy way to get started with the AdWords program. Therefore, these codes can only be redeemed up to 14 days after the creation of an AdWords account. If you created your AdWords account more than 14 days ago, you won't be able to redeem the code.
. Note that Google won't accept or replace expired vouchers.
