Where is the 25 digit code?

I got a Minecraft gift card and wanted to play it right away. The only problem is that I can't find the 25-digit code. For me it says "it'll be added to…" but I did not receive any new messages in my email. There's a code on my card that I had to scratch, but it is definitely too short. Can someone help me with this?

What's on the card?

Is the vll a realms code

This is a map from Mojang for pc & Mac. On the back of the card are the instructions etc.

What is a realms code? 😂
