Technical Background
Promo codes (also called coupon codes or discount codes) are a common promotional tool in e-commerce and marketing. A good promo code should be: unique (avoid duplicate usage), readable (avoid ambiguous characters), and trackable (use prefixes to identify source channels). Common formats include: PREFIX-XXXX-XXXX (with prefix groups), XXXXXXXX (pure random), WORD-NUMBER (word + number combination). Security tip: codes should be at least 6 characters long. Using uppercase + numbers provides approximately 36^8 \u2248 2.8 trillion combinations, far exceeding typical needs.
