# How long are QR codes valid for? Do they expire?

Static QR Codes are valid for as long as you want and will never expire. The only instance where the Code might “expire” is when the link is changed or deleted, rendering it unscannable. We encourage you to create Dynamic Codes so that you have total control as the content or links are replaceable no matter what happens. Plus, it has plenty of other advantages for your campaigns!
