Yes, coupon codes and promo codes typically have an expiration date. This is usually set by the company issuing them. After this date, the code may not provide the same discounts or may not work at all. It's always a good idea to check the terms and conditions of the code for details about its validity period. However, some codes may be valid indefinitely until the company decides to deactivate them. It's always best to use your codes as soon as possible to avoid missing out on the deal.
