What do DoorDash, Uber Eats, and Instacart actually code as?

Order the exact same groceries twice — once walking the aisles, once through a delivery app — and your card can pay you differently for each. Not because anyone changed the rules, but because the two purchases aren't the same merchant as far as the card network is concerned.

This is the flip side of why Walmart doesn't count as groceries: merchant codes decide everything, and delivery apps have their own.

The general rule: delivery apps are restaurants

When you pay through DoorDash or Uber Eats, the merchant is the platform, not the restaurant — and the platforms code as dining on most cards. Our dining category is defined accordingly: restaurants, bars, cafes, fast food, and food delivery, with DoorDash/UberEats coding as dining on most cards.

Practical consequences, straight from our dining ranking:

• A dining multiplier is the one that fires. The Amex Gold's 4x on dining leads our ranking, and it applies to app orders the same as to sit-down meals.
• Your 6% grocery card earns its base rate on a delivery order — even if the bag is entirely groceries.
• The delivery fee and the tip inherit the merchant's code. They're part of the same transaction, so on a dining-coded order they earn the dining rate too. That's a quiet upside: the most annoying part of the bill still earns the multiplier.

Instacart: the honest answer is "check your statement"

Instacart is the one we deliberately won't call for you. Its coding varies — orders can post differently depending on how the purchase is set up. Rather than hand you a confident answer that's wrong half the time, here's the reliable test: place one order, wait for it to post, and see which bonus your card applied. One data point from your own statement beats any blog's generalization — ours included.

What we can say from the data: if an Instacart order posts as groceries, the grocery ranking applies (Blue Cash Preferred's 6% leads it); if it posts as anything else, you're better off paying with your best flat-rate card.

Rideshare is its own bucket too

The same platform logic runs through the rest of the app economy. Uber rides aren't dining — they're transit & rideshare, a separate category covering public transit, rideshare, taxis, parking, and tolls. Right now Discover it Cash Back leads that ranking at 5% — with the usual rotating-category fine print (activate each quarter, combined cap, lower rate after).

One app, two categories: an Uber Eats order codes as dining while the Uber ride home codes as transit. The app on your phone isn't the category — the merchant code behind each transaction is.

The takeaway

Match the multiplier to the code, not the cart: dining cards for delivery apps, grocery cards for the supermarket door, and a statement check for the ambiguous platforms. Every rate above carries a verification date and an issuer source link on its card page, re-checked weekly.
