• Make sure that the code you are entering is a redemption code (24-digit alphanumeric code).
• Make sure that you typed the code correctly. Redemption codes contain both letters and numbers. It's easy to confuse some numbers and letters, such as zero and one with the letters "0" and "I."
• Make sure that you're entering the code at the correct redemption site. Be sure that you enter the code at the redemption site noted on your insert, card, or email.  Go to Redeem a redemption code for subscription retail products or Redeem your purchase for non-subscription retail products.
• Try redeeming the code from a different browser. Access your account information. You may have your subscription or product available and registered in your Adobe account. For more information on your Adobe ID account, see Manage your Adobe ID account.
