Sorry for the misuse of AIBU.
I've sold an item on Vinted and it's telling me the buyer it using InPost 24/7 and has given me a digital label to download. This label is not like the Evri ones - it has no address on it, it's just a QR code. Apparently I need to scan it at my nearest drop off point and put the parcel in a locker. Im so confused as to how it will arrive at someone's address this way?! How does anyone know where it's going if it gets placed in a locker with no label on? 
I'm a bit concerned about things not arriving!
