How long is the QR code for a label good for?

I purchased a QR code label last night, forgetting that today is a government-observed holiday. Will my QR code still work tomorrow at the post office? TIA

@ndbluegold   It should just like a regular shipping label.  I print mine a day in advance often and don't change the date I will ship on the label, I always forget that spot.

Great. Thanks so much!
