QR code time frame?

[sarahdore84]

Does anyone know if the QR codes have a time limit before they expire?

Buyer paid for Royal Mail postage, I let them know that I am away at the moment and can't post until the 23rd which they are fine with. But I don't know if the QR will have expired by then

Postage labels/QR codes have to be used within 14 calendar days.
