Instacart can code as a grocery store, a delivery service, or something else entirely, depending on your bank and the order type. That single variable determines which card earns the most. Here is how to figure out which category your card sees, and which card to use in each scenario.
How Instacart Codes: The Key Variable
Instacart processes transactions through several merchant category codes depending on the order:
- MCC 5411 (Grocery Stores and Supermarkets): The most common code for Instacart orders. When this appears, grocery bonus categories apply.
- MCC 5912 or 5999 (Drug Stores / Miscellaneous Retail): Appears for some pharmacy or non-grocery Instacart orders
- MCC 7299 (Services): Sometimes used for delivery fees or Instacart+ membership charges specifically
The core order itself (groceries) most commonly codes as MCC 5411, but this is not guaranteed across all issuers. Check your first Instacart statement and look at the merchant category shown in your card app or statement details. Your bank may display “Grocery” or the actual MCC.
Best Cards When Instacart Codes as Grocery (MCC 5411)
| Card | Grocery Rate | Annual Cap | Annual Fee | Verdict |
|---|---|---|---|---|
| Amex Blue Cash Preferred | 6% cash back | $6,000/yr then 1% | $95 | Best overall if you spend under $6K/yr on groceries |
| Amex Gold | 4x Membership Rewards | $25,000/yr then 1x | $325 | Best if you value transferable points over cash back |
| Chase Sapphire Preferred | 3x on online groceries | None stated | $95 | Note: excludes Target, Walmart, wholesale clubs; Instacart may qualify |
| Citi Custom Cash | 5% auto-detected | $500/mo then 1% | $0 | Best no-AF option if grocery is your top monthly spend category |
| Capital One SavorOne | 3% on grocery stores | None | $0 | Solid no-AF fallback |
All rates verified from issuer terms as of 2026-03-22. Instacart must code as MCC 5411 (grocery) for these category rates to apply.
Amex Blue Cash Preferred: The Grocery Leader
The Blue Cash Preferred Card from American Express earns 6% at U.S. supermarkets, capped at $6,000 per year in grocery purchases (then 1%). At $500/month in grocery spending, you hit the cap exactly, earning $360 in cash back before the cap and $60 after, for a total of $420 per year. At $95 annual fee, the net grocery benefit alone is $325, before considering the card’s other benefits (6% on select streaming, 3% on gas and transit).
Important Amex BCP exclusions: Costco, Walmart, and Target do NOT earn the 6% grocery rate. They are classified as wholesale clubs and superstores, not supermarkets. If Instacart is your primary grocery source and codes as MCC 5411, the BCP applies. If you use Instacart to order from Costco specifically, verify whether the Costco-via-Instacart order codes as 5411 or 5411 is overridden by Costco’s own MCC.
The Instacart Mastercard: Worth Considering?
Instacart offers its own co-branded Mastercard, which earns 5% back on Instacart purchases, 5% back on travel booked through its portal, and 2% on other purchases. The card has no annual fee.
The 5% on Instacart is competitive with the Amex BCP’s 6% on grocery, but the gap is notable: if you spend $4,000 per year on Instacart, the BCP earns $240 vs. the Instacart Mastercard’s $200. The BCP’s $95 annual fee costs $95, leaving a net advantage of $-55 for low spenders but a growing advantage as spend increases. At $6,000/year in Instacart/grocery purchases, BCP earns $360 vs. Instacart card’s $300, netting BCP ahead by $-35 after the fee. Above the $6,000 BCP cap, the Instacart card wins on Instacart purchases specifically.
The Instacart Mastercard’s 5% is also locked to Instacart. The BCP’s 6% applies to all U.S. supermarket purchases, making it more versatile for households that shop in-store too.
Best Cards When Instacart Codes as Services (Not Grocery)
If your bank categorizes Instacart as a service rather than a grocery purchase, category bonus cards lose their advantage. In that case:
- Citi Double Cash (2% on everything): Best flat-rate no-AF card. If grocery categories do not apply, 2% is a reliable baseline.
- Capital One Venture X (2x miles everywhere, verified as of 2026-03-22): Premium option at 2x if you value miles over cash back
- Chase Freedom Unlimited (1.5% on everything): Weaker than Citi Double Cash but useful if you are in the Chase ecosystem
How to Check Your Instacart Coding in 30 Seconds
- Make a small Instacart purchase (even $20)
- Check your card statement or banking app 1-2 days after the charge posts
- Look for the merchant category label: “Grocery,” “Supermarkets,” “Services,” or similar
- Many card apps show category icons (shopping cart for grocery, etc.) next to the transaction
- If you cannot tell from the app, call your card’s customer service and ask what MCC was applied to the Instacart charge
Bottom Line
When Instacart codes as grocery (most common with personal accounts ordering from standard grocery chains), the Amex Blue Cash Preferred at 6% is the highest-earning option up to $6,000/year, beating the Instacart Mastercard’s 5%. If grocery categories do not apply, use a flat-rate card like Citi Double Cash. Check your first Instacart charge category to confirm how your bank classifies it before optimizing.
Frequently Asked Questions
Q: Does Instacart+ membership fee earn grocery rewards?
A: The Instacart+ subscription charge may code separately from grocery orders, often as a service fee (MCC 7299). Grocery category bonuses typically do not apply to the membership fee itself, only to the grocery order charges.
Q: Does ordering from Costco via Instacart earn grocery rewards?
A: This is issuer-dependent. Costco orders via Instacart may code as Costco (warehouse club, MCC 5300) rather than grocery, bypassing grocery bonus rates. Test with a small order and check your statement.
Q: Is the Amex BCP 6% cap per calendar year or per membership year?
A: The $6,000 cap on U.S. supermarket purchases resets each calendar year (January 1). Plan large grocery spending accordingly.
Q: Does the Amex Gold 4x apply to Instacart?
A: The Amex Gold earns 4x at U.S. restaurants (MCC 5812 and similar) and 4x at U.S. supermarkets (MCC 5411). If Instacart codes as MCC 5411, the 4x applies. If it codes as restaurants or services, the rate varies. Amex typically categorizes Instacart grocery orders as supermarkets.
