    X is a random character; every other symbol is kept as typed. If a pattern is set, the length slider is ignored.
    Generation runs in your browser with crypto.getRandomValues(); uniqueness is checked only within the current export.
    Your CRM or store sets the discount, expiration date, usage limit, and brute-force protection after code import.

    Generate bulk promo codes

    Use this promo code generator to create a batch of random coupon-style codes for email campaigns, referral tests, loyalty experiments, offline flyers, QA data, or ecommerce imports.

    • Generate 1 to 1,000 codes in one browser session.
    • Add a prefix such as SALE-, VIP-, or SPRING-.
    • Use a pattern such as XXXX-XXXX when codes need separators.
    • Export TXT for a simple list or CSV for import workflows.

    Uniqueness and brute-force limits

    Codes are generated with `crypto.getRandomValues()` and deduplicated only within the current export. The tool does not compare against earlier exports or your ecommerce database.

    N is the possible code space, A is alphabet size, and L is the number of random characters.

    Short public codes are easier to guess. Real brute-force protection must be enforced by the server or store: rate limits, attempt throttling, expiry dates, usage limits, and validation against old code batches.
