The Pepsi "Number Fever" fiasco: marketing's most expensive mistake

We have all made a mistake from time to time. The odd typo on a Facebook post, liking the wrong photo, or firing off an email to exactly the wrong person. We are only human, after all. But let me tell you a story that will make you squirm.

The setup

It is 1992, Manila, in the Philippines. Pepsi-Cola Philippines is being comprehensively outsold by Coca-Cola, roughly 75 per cent to 17 per cent market share. Something had to give.

Enter Number Fever

Great name. Simple plan. Every bottle of Pepsi, Mountain Dew and 7 Up would carry a three-digit number printed inside the cap, with cash prizes ranging from 1,000 pesos all the way up to a life-changing grand prize of 1,000,000 pesos.

The campaign took off. Sales jumped by close to 40 per cent. High fives all round.

And what do we do when a campaign is going well? We go harder. Elated officials added five more weeks to the original twelve-week run. The new ads promised: "More chances to be a millionaire!" (Drogin, 1993)

As the weeks wore on, more than 51,000 people won cash prizes. The vast majority won the smallest prize, 100 pesos, but 17 lucky people won a full million pesos and were paraded through Pepsi's advertising like conquering heroes. (Drogin, 1993)

What could possibly go wrong?

It is time to announce another grand-prize winner of one million pesos. And the winning number is...

349.

Someone, somewhere, had missed a rather important memo. 800,000 caps had the number 349 printed inside them. Take a moment to imagine being the person responsible for that. You would not tidy your desk. You would simply gather your things and quietly leave the country. This was not a stray typo on a Facebook post.

Someone missed the memo. 800,000 caps had the number 349 printed inside them. Imagine being the person responsible.

When things go pear shaped

Thousands upon thousands of Filipinos turned up to claim their million pesos. Pepsi ducked and weaved, citing improper security codes on the caps and a computer glitch. The message, essentially: "Sorry folks, our mistake, you have not actually won a million pesos, but here, have a Pepsi."

It got serious fast. Riots. People were killed. Pepsi trucks were set alight, bottling plants were firebombed, and executives quietly left the country. Thousands of furious Filipinos formed anti-Pepsi organisations. One member, Paciencia Salem, 64, said her husband had died of heart failure at an anti-Pepsi rally, and she was prepared to do the same.

"Even if I die here, my ghost will come to fight Pepsi," she promised. "It is their mistake. Not our mistake. And now they won't pay. That's why we are fighting." (Drogin, 1993)

Eventually everyone settled down enough to file a 400 million peso class action against PepsiCo. The company paid out roughly 10 million in restitution and legal fees, and, as a gesture of goodwill, close to 500,000 to non-winning claimants. It is fair to say the campaign had well and truly lost its sparkle. In 2006, the Supreme Court of the Philippines cleared Pepsi of all criminal charges and ruled it was not liable for the riots.

An epic failure by any measure.

What every marketer can learn from it

Now, I could just leave you with the schadenfreude, but there are real lessons buried in the wreckage, and they apply whether you are running a national soft-drink promotion or boosting a post for fifty dollars.

• Test small before you go big. Number Fever was scaled up, an extra five weeks, "more chances!", before anyone had properly stress-tested the mechanics. When a campaign is working, the instinct is to pour fuel on it. Pour it on a fire you have actually checked is under control.
• One point of failure is one too many. The entire disaster hinged on a single printing process with no real safeguard. Whether it is a promo code, a landing page or a tracking pixel, the bit you are not watching is the bit that will bite you.
• Own the mistake fast, and generously. Pepsi's ducking and weaving turned a printing error into a national crisis. When something breaks, and it will, the businesses that come out intact are the ones that front up quickly and make it right, rather than reaching for "computer glitch".
• Read the fine print before you promise the world. "Be a millionaire" is a wonderful hook, right up until 800,000 people take you literally.

None of that requires a marketing degree. It just requires checking the thing before you shout about it, which remains the least glamorous and most valuable habit in the business. It is exactly why we test, QA and sanity-check every campaign before we scale it, Meta ads, Google Ads or otherwise. The boring checks are the ones that save you from becoming a case study.

And if it is any comfort, Pepsi is in famous company. Coca-Cola once replaced its own formula with New Coke and had to bring the original back within months. Hoover offered free flights with purchase in the early nineties and very nearly gave itself away. Big brands, big budgets, big mistakes. It happens to everyone.

So there it is. Next time you make a little whoopsie, just think of Pepsi. Things could always be worse.

If you know of, or are personally responsible for, a monumental marketing mistake, feel free to confess in the comments. Unless, of course, it is something I have done, in which case we shall never speak of it again.
