Arknights codes not working?

Promo codes expire fast and have specific rules. Here's why your Arknights code might be throwing an error:

• The code has expired. Event codes and milestone codes tend to expire quickly, sometimes within hours. Try redeeming new codes as soon as they appear on our list to avoid missing out.
• Check for typos and capitalization. Most codes are case-sensitive. Make sure you’ve entered it exactly as shown, including capital letters, numbers, and special characters. Copying and pasting is the safest approach.
• Check your in-game mail. In Arknights, rewards are often sent to your in-game mailbox rather than appearing on screen. Check your mail, gift box, or inbox after redeeming to collect your items.
• Update required. New codes are sometimes tied to the latest game version. If a brand-new code isn’t working, make sure your client is fully updated.
