What is the difference between a RedotPay referral code and a promo code?

A referral / invite code like b30wr is entered during new-account signup for an eligible $5 path. A promo / coupon code like REDOT2 or REDOT20 is entered on the card-order checkout screen for 20% off issuance fees.

Can I stack b30wr with REDOT2 or REDOT20?

Yes in sequence: use b30wr at registration, then later use REDOT2 or REDOT20 when ordering a card. They use different fields and do not replace each other.

RedotPay referral vs promo code

b30wr is a referral / invite code for new accounts ($5 path). REDOT2 and REDOT20 are promo / coupon codes for card checkout (20% off). Mixing them is the fastest way to think a code is “not working.”

FAQ

Can I add b30wr after I already registered?

Usually no — RedotPay invite codes are for the registration step. If you skipped it, focus on REDOT2/REDOT20 at card checkout.

Does the $5 bonus pay the card fee?

Treat them as separate. The $5 path does not replace a 20% checkout discount. Confirm both rewards inside the app.
