Circle App Referral Code — Discontinued

Why Your Circle App Referral Code Doesn’t Work Anymore

Referral codes only work if there’s a live app on the other end for a new signup to land in, and Circle’s consumer app is the piece that’s gone. We tested the referral link directly (circle.com/invite/U42PTG) and it returns a plain 404 — not a redirect to a new signup flow, just “not found.” Circle’s own homepage now describes itself as a platform for banks, fintechs, and developers building on USDC, with no mention of a peer-to-peer app, referral bonuses, or anything aimed at individual consumers. Between the dead link and the company’s own repositioning, that’s our two confirmations that the referral program specifically — not just this one code — is discontinued.

If you’re curious about the broader Circle Pay shutdown rather than just the referral mechanics, see our sister page, Circle Pay Promo Code: Status Update, which covers the app’s discontinuation in more depth.

For context, since people still search this term: entering U42PTG at signup got you $5 in bonus cash, conditional on sending at least $25 through the app within your first two weeks. Once you had an account, you could share your own personal referral code with friends and earn another $5 every time someone signed up through it and hit that same $25-sent threshold. It was a fairly standard fintech-app referral loop — give $5, get $5 — for a product that no longer exists in that form.
