WASHINGTON, D.C, – 10/01/25 – This week, Senator Jim Banks (R-Ind.) introduced the bipartisanZip Code Bill. This bill would require the Postal Service to give certain communities in Indiana their own ZIP Codes, making mail delivery clearer and more efficient.

Senators Michael Bennett (D-Colo.), Markwayne Mullin (R-Okla.) and John Hickenlooper (D-Col.) are original cosponsors of the legislation.

Senator Jim Banks (R-Ind.): “I’ve heard from too many Hoosiers frustrated by mail delays and mix-ups. Our growing communities deserve their own ZIP Codes so families and businesses can count on reliable service.”

Mayor of Carmel, Sue Finkam: “Having multiple zip codes in our area creates confusion for residents and homebuyers. For example, people purchase homes with Carmel addresses, assuming they are within the Carmel city limits and school district, only to later learn that’s not the case. I support an effort to establish a single zip code that reflects our true community boundaries, protects families from this kind of confusion, and fosters one identity.”

Mayor of Lawrence, Deb Whitfield: “Having our own Zip Code is more than just a number on mail. It’s about identity, efficiency, and opportunity. It gives our city the recognition it deserves, improves services for residents and businesses, and strengthens the sense of community we all share. Thus, this step ensures that the people of Lawrence, that I serve are better connected, better represented, and better supported.”

Mayor of Noblesville, Chris Jensen: “I support legislation for USPS to assign single, unique ZIP Codes for communities. This will eliminate longstanding address confusion for businesses, residents, and newcomers by saving time, reducing errors, and improving local services. The clear boundaries also help ensure tax collections are accurately divided among the communities they serve, I applaud Senator Banks for introducing a bill to give cities a dedicated zip code, provide clarity, and have a lasting impact on residents and business owners.”

Mayor of Westfield, Scott Willis: “We fully support this bill, as a single zip code offers a number of advantages for Westfield. It enhances clarity in identifying business and residential locations, eliminates confusion caused by multiple zip codes, and simplifies addressing for both mail delivery and emergency response. One zip code improves the accuracy of data and analytics, especially with demographics and marketing, by not being fragmented.”

Mayor of Zionsville, John Stehr: “We have people who live in Zionsville, but they have a Brownsburg, Lebanon or Whitestown ZIP code, so this bill will help foster community by reflecting our true boundaries, it will also simplify services and make emergency response more efficient by eliminating confusion over who has jurisdiction for a particular location.”
