For the contest, the company released 11 unique dollar bills in 11 U.S. cities. For 11 consecutive days starting Tuesday, Taco Bell will release a serial number for the dollar bill in the city of the day. Participants can check the website to see if they have a match.

The 11 winners will be awarded a $10,000 gift card - which Taco Bell claims is enough for life.
The company says the $10,000 figure is based on a consumption of $216 per year for 46 years.
Estimated odds of winning are one in 2.4 billion, according to the website.
So far, Taco Bell has only released a serial number for Los Angeles.
