Code or Referral Link — Which Should You Use?
They land in the same place. Tapping a referral link before you install the app pre-fills the invite code automatically, so there’s nothing to type. Typing 594CWW manually during sign-up does the same thing — useful if you already have the app store listing open, or if a link got stripped out somewhere (some messaging apps mangle deep links). Use whichever is easier in the moment.

Where to Type the Code
Install “Upside: Gas & Food Cash Back” from the App Store or Google Play.
Start creating a new account — this only works for first-time sign-ups.
Code: 594CWW
During onboarding, find “Enter Invite Code” and type 594CWW.
If you don’t see that screen, check your profile or referral settings after sign-up — it’s sometimes tucked in a different spot depending on the app version.
- You’ve had the app before. Invite codes only apply to brand-new accounts — reinstalling doesn’t count as new if the account already exists.
- You added it after finishing sign-up. Some app versions lock the invite-code field once your account is created.
- Your first purchase was under $10. The referral bonus needs a qualifying purchase of $10 or more before tax and tip.
- You typed it with a typo. It’s 594CWW — no spaces, all caps doesn’t matter, but double-check the characters.

Code Not Working? Common Fixes
Frequently Asked Questions
Do I have to use the code, or can I just click the link?
Either works. The link pre-fills the code for you; typing it manually does the exact same thing.
What do I get for using the GetUpside code?
An extra 15¢/gallon on your next gas purchase and 10% off your next restaurant or grocery order, once your first purchase is $10 or more.
I entered the code but don’t see a bonus — why?
Check that your account is genuinely new, the code was entered before you finished sign-up, and your first purchase met the $10 minimum. Any one of those being off is the usual culprit.
