Referral Code Not Working? A Universal Troubleshooting Checklist

If a referral code doesn’t work, it’s usually one of these nine issues. Walk through this checklist to fix it fast.

Quick Checks

1. Try in a fresh browser or incognito (logged-in state can block bonuses)
2. Confirm region and eligibility (new customer, time-bound, device limits)
3. Verify the link isn’t expired or already claimed
4. Disable ad blockers or privacy extensions temporarily
5. Check brand status page or promotions fine print

Advanced Fixes

• Use a verified invite flow from the brand’s app (vs. pasted URL)
• Switch to mobile or desktop—the offer may be device-specific
• Try a different network (VPNs/proxies can break tracking)
• Clear cookies for the brand’s domain and retry

If it still fails, ask the referrer for a fresh link or try another verified link on Codiroo.
