WASHINGTON, D.C.—Senator Jim Banks (R-Ind.) has introduced the bipartisan “Zip Code Bill,” legislation aimed at requiring the U.S. Postal Service (USPS) to assign unique ZIP Codes to several growing Indiana communities. The bill, cosponsored by Senators Michael Bennet (D-Colo.), Markwayne Mullin (R-Okla.), and John Hickenlooper (D-Col.), seeks to clarify and improve mail delivery.

The legislation directs the USPS explicitly to designate single, unique ZIP Codes for the following communities in Indiana:
- Carmel, Indiana
- Lawrence, Indiana
- Noblesville, Indiana
- Westfield, Indiana
- Zionsville, Indiana
Senator Banks stated, “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”.
Mayors from the affected cities have voiced strong support, citing benefits ranging from improved identity to more efficient emergency services:
- Carmel Mayor Sue Finkam noted that multiple ZIP Codes create confusion for residents and homebuyers, sometimes leading them to mistakenly believe they are within the Carmel city limits and school district.
- Lawrence Mayor Deb Whitfield said a unique ZIP Code is “more than just a number on mail,” calling it a matter of “identity, efficiency, and opportunity” that will strengthen the sense of community.
- Noblesville Mayor Chris Jensen highlighted that a single ZIP Code will “eliminate longstanding address confusion for businesses, residents, and newcomers” and improve the accurate division of tax collections.
- Westfield Mayor Scott Willis stated that a single ZIP Code enhances clarity in identifying locations, simplifies addressing for emergency response, and improves the accuracy of demographic data and analytics.
- Zionsville Mayor John Stehr pointed out that many Zionsville residents currently have Brownsburg, Lebanon, or Whitestown ZIP Codes, and the bill will “help foster community by reflecting our true boundaries” and make emergency response more efficient.
