Why does my delivery referral code say invalid?

Most often the code is region-locked to a different city, or the minimum basket has not been met. Try a second code before giving up.

Do delivery referral credits expire?

Usually yes, commonly 14 to 30 days after being issued. Use them on the next order rather than saving them.

Can I use a referral code on the web instead of the app?

Sometimes, but app-only offers are common in delivery. If the web checkout rejects it, retry inside the app.

Do both people get the reward?

In grocery and courier apps, almost always. Some rapid-delivery promos reward only the new user, so read the offer text.

Delivery apps with referral codes: what each one pays

28 January 2026·6 min read·Delivery

Delivery is the category where referral codes get used the most, because the barrier is tiny: someone is already hungry, already out of milk, or already needs a parcel collected. A code that removes the delivery fee converts on the spot.

The trade-off is size. Delivery bonuses are small compared with finance or travel, so the strategy is volume and timing rather than a single big payout.

Grocery delivery: credit on the first basket

Grocery apps almost always structure the offer as money off a first order above a minimum basket value, with matching credit to the referrer once that order is delivered. Because grocery baskets are large, the minimum is easy to clear.

These are the most reliable delivery referrals to share, since the friend was going to buy food anyway.

Parcel and courier apps

Peer-to-peer courier and parcel platforms pay a flat credit after the first completed shipment. Marketplace sellers are the ideal audience — they ship constantly and are highly price sensitive.

Best audience — Anyone selling on second-hand marketplaces.
Typical trigger — One completed, non-refunded shipment.
Watch for — Credits that expire within 30 days of issue.

Convenience and rapid delivery

Rapid delivery apps run aggressive new-user offers, sometimes stacking a referral credit with a first-order promo. They also churn hardest: an app that pays €10 today may pull the program entirely when a funding round ends.

Check the program page for the last time a code was reposted. Freshness matters far more here than in stable categories.

Why delivery codes go stale so fast

Delivery platforms rotate offers city by city. A code can be perfectly valid in Berlin and dead in Lisbon on the same day. If a code fails, try another from the same program page before concluding the program has ended.

How to share a delivery code well

Lead with the practical detail: what the friend gets, the minimum basket, and the city. Vague posts get ignored; a line like "€8 off a first grocery order over €30, works in Dublin" gets used.
