Get the app. It’s listed as “Upside: Gas & Food Cash Back” on the App Store and Google Play — or jump straight there via this link or this one.
Sign up with your phone number or email. This has to be a first-time account — the bonus doesn’t apply to existing users.
Code: 594CWW
Enter code 594CWW when prompted for an invite or referral code.
Turn on location access so the app can show gas, grocery, and restaurant offers near you.
Claim a gas offer and fill up for $10 or more before tax and tip, then check in at the pump in the app to confirm your purchase and trigger the bonus.
Is Upside Available Where You Live?
Upside covers more than 30,000 gas stations, grocery stores, and restaurants nationwide and keeps adding new markets. Coverage still varies by city and even by neighborhood — the app will show you what’s actually live once location access is on. If your area is thin right now, it’s still worth signing up with the code; your referral credit is attached to your account and ready whenever offers show up near you.

The referral bonus is a one-time-per-account thing, but it’s not the only ongoing earning built into the program: you get 10¢ every time someone you personally refer makes a purchase over $5 through the app, for as long as they keep using it. Combined with everyday cash-back offers on gas, groceries, and dining, most of what you save comes from continuing to use the app after the initial bonus, not just the sign-up itself.
Curious how much 15¢/gallon really saves you? See GetUpside Promo Code for Gas App (savings breakdown). For the full guide with every FAQ we’ve got, see GetUpside Promo Code. And for another free receipt-based cash-back app, check out ReceiptJar.

Who’s Eligible
You need to be a new Upside user — if you’ve had the app before under any account, the invite code won’t add a bonus retroactively. You also need to be 18 or older with a valid U.S. payment method, and your first purchase has to hit the $10 minimum before tax and tip for the referral bonus specifically (separate from whatever everyday cash-back offer is showing at your local station).
Frequently Asked Questions
What’s the GetUpside promo code for the gas app?
594CWW. New users get an extra 15¢/gallon on their next gas purchase plus 10% off dining or groceries, once their first purchase is $10 or more.
Do I need to live somewhere Upside is fully active?
No — sign up regardless. Upside adds markets constantly, and your invite code and bonus stay valid on your account.
Is this a one-time bonus or does it keep paying out?
The referral bonus itself is one-time, but you also earn ongoing 10¢ credits whenever people you’ve referred make purchases over $5, plus regular everyday cash back on gas, groceries, and dining as you keep using the app.
