Usually the certificate number is right below the barcode (if there is one) or it's printed towards the top and labelled as such. On some occasions, I've seen other formats, but that's generally how it appears. If you have more than one My Best Buy™ membership, that could be causing the error as certificates can only be used when attached to the membership they were issued to.
Alternatively, you can try to see if the certificate/offer is listed in your online account. The first article below explains the steps in more detail.

Good afternoon, tdorf,
Welcome to the Best Buy forum, and thank you for connecting with us.
This is the time of year when a bonus certificate can really come in handy. Maybe you have one or two more gifts to purchase and a bonus certificate would help tie the ribbon on your holiday shopping for the year. I will have to double check the mail when I get home. The option to manually enter a certificate during checkout on BestBuy.com was removed a few years ago, and in most cases, a certificate will already be attached to a member's rewards account and they would just need to select the certificate during checkout. Did the mailer you receive mention a start and end date for the bonus certificate?
