Referral Codes Not Working? The Ultimate Troubleshooting Guide (2025)

If a referral code isn’t working, it usually comes down to eligibility, expired promotions, region limits, device mismatches, or broken tracking. This long-form guide walks you through fast checks and advanced fixes, plus brand-specific patterns we see across finance, crypto, travel, and food apps.

Quick Checks (Do These First)

1. Use incognito or a fresh browser profile to avoid cookie conflicts.
2. Confirm new-user eligibility and region availability.
3. Open the link in the app after installing (mobile-first flows).
4. Disable aggressive ad/tracking blockers temporarily.
5. Check promotion terms and end dates.

Advanced Fixes (Tracking & Device)

• Try a different device (some offers are mobile-only or desktop-only).
• Switch networks (VPNs/proxies can invalidate tracking).
• Clear cookies for the brand domain and retry the flow.
• Request a fresh invite link or use a verified Codiroo link.

Common Eligibility Pitfalls

• Already registered or previously claimed a similar promo.
• Existing device/account footprints from family or shared devices.
• Payment or identity verification requirements not completed.

Brand Patterns (Examples)

• Finance apps: strict new-user and KYC checks; device/account conflicts.
• Crypto exchanges: region and compliance limits; in-app flow preferred.
• Travel/food: time-limited promos; device-specific deep links.

When to Contact Support

If all fixes fail, contact the brand with timestamps, device, browser, and country. Ask whether the promotion is active for your account and region.

FAQ: Referral Code Not Working

• Why do I lose bonuses when I’m logged in? (tracking attaches to current user)
• Why do VPNs break referrals? (geo + fraud rules)
• How do I know if a link is expired? (brand terms + timestamped posts)
