Study Finds 76% of Coupon Codes Work at Checkout
NEW YORK, July 18, 2026 /PRNewswire-PRWeb/ — Multi-country research across 11 regions finds that most coupon code failures were not due to expired codes, but to terms and conditions shoppers did not check before checkout.
Our research shows that most coupon code failures are caused by overlooked terms and conditions not expired codes. Understanding the offer requirements can significantly improve checkout success.” — Anderson Joe, CMO, CouponDopa
A new study testing 1,000 coupon codes across 11 countries found that three in four online discount codes applied successfully at checkout, while the remaining failures were tied more often to unmet terms than to expired or invalid codes.
The research was conducted by CouponDopa, a multi-regional coupon platform operating in 11 countries. Codes were tested across multiple retail categories in July 2026 to measure real checkout success rates.
KEY FINDINGS
Overall success rate: 76%. Overall failure rate: 24%. Highest-performing country: Netherlands, 81%. Lowest-performing countries: Poland and Italy, tied at 70%. Highest-performing category: Electronics. Lowest-performing category: Travel. Desktop success rate: 78%. Mobile success rate: 74%.
The study’s most significant finding was not the failure rate itself, but the reasons behind it.
“The assumption most shoppers make is that a coupon code doesn’t work because it’s expired,” said Anderson Joe, CMO at CouponDopa. “Our testing found that expiry was rarely the primary issue. In most failed attempts, the code was still active, but the shopper’s cart did not meet a listed condition, such as a minimum spend or a region restriction.”
WHY COUPON CODES ACTUALLY FAIL
Minimum spend not met: the most common reason for failure across all 11 regions, since many codes require a basket value above a set threshold.Region-specific restrictions: codes valid in one country frequently failed in another.Unread terms and conditions: codes were applied to excluded categories, sale items, or specific product ranges without checking eligibility first.Delivery and shipping thresholds: free shipping codes requiring a minimum order value were sometimes mistaken for blanket offers.
No exact percentage breakdown of failure causes is available. Minimum spend is confirmed as the single most common cause; the other three were not ranked against each other.
“In our view, a code that fails because of an unmet minimum spend is not necessarily a broken code,” said Anderson. “It may simply be a condition the shopper did not see before checkout.”
REGIONAL FINDINGS — NETHERLANDS LEADS
Country Success Rate
Netherlands 81%
Germany 79%
United States 77%
Canada 77%
United Kingdom 76%
Australia 75%
New Zealand 74%
France 73%
Spain 72%
Poland 70%
Italy 70%
Netherlands recorded the highest success rate of the 11 regions tested. Germany followed closely. The United Kingdom matched the overall study average, and Canada and the United States recorded the same rate. Poland and Italy recorded the lowest rates in the study, tied at 70%.
ELECTRONICS OUTPERFORMS TRAVEL
Electronics recorded the highest coupon code success rate of any category tested, at 80%, while travel recorded the lowest, at 69%.
“Electronics codes in our sample tended to carry fewer conditions,” noted Anderson Joe. “Travel codes more often included conditions tied to dates, destinations, or booking windows, which may explain the difference.”
MOBILE SHOPPERS RECORD LOWER SUCCESS RATES
Desktop checkouts recorded a 78% success rate compared with 74% for mobile, a 4-point gap. Researchers said the difference may relate to how terms are displayed on smaller screens, though this was not directly tested.
“We saw a consistent gap between desktop and mobile across our markets,” said Anderson Joe. “We can’t say precisely why from this data alone, but it’s a pattern worth further study.”
