Economic Development Director Jeff Reiter says more than 100 businesses and organizations will host special events and offer refreshment throughout the city.
"We got the idea from other cities, those other cities are incredibly small. And what we've done here I would say is completely plumed into something I don't think has been seen in another city before. So it may be a new model that people adopt here for years to come in other cities."
The city has also handed out thousands of "zip code t-shirts," featuring Bettendorf's Zip Code Day logo.
Friday's party will also kickoff a week-long celebration ending next Saturday (6/4) with the annual Downtown Festival. Ten people will win a special cash prize of $527.22.
