used to be instant code!! it is not anymore in my case

I have bought these previously in 2018 and have gotten my code instantly right after purchase. In 2019, however, it has been about 3 hours and it is still pending verification. I have not received any emails from amazon or anything else for that matter. Prior to purchase, I was asked to verify my card number, and I am assuming this was done to prevent fraudulent charges; however, why does this verification take so long? Just send an email to verify the purchase and be done with it!
