Free Random Code Generator
Generate codes for testing and simple use cases.
If these codes will be redeemed in person, shared publicly, or must only work once — you'll need more than a generator. See how Coupon Carrier handles secure redemption.
No redemption protection
This tool creates random codes only. It does not prevent reuse, track redemptions, or verify codes in person.
Can't generate {{formattedNumberOfCodes}} codes with that code length and character set.
Built for Any Usecase

The Hard Part
You've Got Codes. Now What?
Generating codes is easy. Making sure they're only redeemed once — especially in person — is where most systems fail.
- For Restaurants & Retail
Run in-person offers that staff can verify by tap or scan — no POS integration required.
- For E-commerce Stores
Automate delivery of unique codes through your online stack.
This free generator is not a fit if:
- You need to prevent multiple redemptions
- Staff must validate offers in person
- You need an audit trail of usage
- The campaign cannot fail on launch day
Frequently Asked Questions
- What's the difference between this generator and the full service?
- This free tool is great for generating a simple list of codes. The full Coupon Carrier service automates the entire delivery process. It connects to your apps to automatically send codes, tracks redemptions, and creates trackable digital vouchers for in-store use.
- Can I use this as a gift card generator?
- Yes. Many of our customers use the generator to create lists of unique gift card numbers. You can set a numeric-only character set and a pattern like `####-####-####-####` to match the format of standard gift cards, then import the list into your POS system.
- Is this tool suitable for creating voucher codes?
- Absolutely. You can create human-readable codes (e.g., `FREE-DRINK-123`) and then import them into Coupon Carrier to deliver them as trackable digital vouchers using our "Mark as Used" button or QR code scanner service.
