Free Random Code Generator
Generate static codes for testing and simple use cases.
Not suitable for real campaigns, in-store redemption, or preventing reuse. For that, see how single-use vouchers work — or explore printable vouchers for offline campaigns.
This tool does not:
- Prevent code reuse
- Track redemptions
- Work for in-store campaigns
- Support staff validation
Test a real single-use voucher
Get a voucher → redeem once → try again (blocked)
Can't generate {{formattedNumberOfCodes}} codes with that code length and character set.
Know the Limits
Where Static Codes Fail
Random codes work for testing. But the moment they're used in the real world, things break down fast.
- In-Store Promotions
No way to mark codes as used. One screenshot turns a single-use offer into unlimited redemptions.
- Events & Venues
No validation at the door. Anyone can screenshot and share a code. Staff have no way to check if it's already been used.
- Multi-Location Campaigns
No central control. Each location is a silo with no shared view of which codes have been redeemed.
Need printed coupons that actually work?
Static codes on a flyer get shared and reused. Printable vouchers give each piece its own unique, trackable QR code.
The Hard Part
You've Got Codes. Now What?
Generating codes is easy. Making them work in the real world is where most campaigns fail.
- For Restaurants, Retail & Events
Run in-person offers that staff can verify by tap or scan — no POS integration required. Codes are marked as used in real time, so they can't be redeemed twice.
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
- You need redemption tracking or reporting
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.
