How to Use a DoorDash Promo Code

The promotions field sits in the checkout screen, below the payment section on mobile and in the right-hand order summary on desktop. It accepts one code per order. Codes are not case-sensitive, but a trailing space pasted from an email will cause a rejection that looks identical to an invalid code.

When you apply a code, DoorDash runs three checks in sequence: does this code exist and is it live; is this account eligible for it; and does the current cart satisfy its conditions. Failing the first returns "invalid", the second "not eligible", and the third a message naming the unmet condition — usually the minimum subtotal.

If all three pass, a named discount line appears in the order summary. That line is the confirmation. A code that is accepted without producing a discount line has applied at zero value, which happens when the qualifying item is out of stock or was added from the wrong menu section.

One further check runs at order placement rather than at code entry: the eligibility re-check. For new-customer offers in particular, this is where DoorDash matches your device, address, phone and payment method against prior accounts. A code removed at the payment step failed here, not at entry.

Finally, note what the discount applies to. The subtotal, and only the subtotal. Delivery fees, service fees, taxes, small-order fees and tips are all outside it. This is the source of most disappointment with percentage codes on small orders.
