Code Activation | Avast

Activation codes never use the letter "O" (they use the number zero) or the letter "I" (they use the number one).

If you bought the software via a third-party retailer (like Amazon or Best Buy), there may be a delay of a few hours before the code becomes valid in Avast's system. If the issue persists for more than 24 hours, contact Avast Support with your proof of purchase. avast code activation
