Need help registering my new Starbucks card - keeps giving an error

Hi! Just wanted to ask if anyone here has experienced this. I’m trying to register a new Starbucks card but I keep getting an error saying there may be an issue with the card number or the security code.

I already tried entering the card number with and without spaces. I also used the SKU number at the top of the sticker (the one that looks like a scratch code), but it still won’t work.

Has anyone dealt with this before? Any tips on how to fix it or what exact numbers I should be using? 🙏
