ZIP Codes vs ZCTAs
These ZIP codes are based on USPS postal data and US Census ZCTA references. ZIP codes represent mail delivery areas rather than precise legal boundaries. For exact service coverage—especially for utilities, emergency services, or official purposes—verify with the specific service provider or USPS.
Frequently Asked Questions
How do I verify the correct ZIP code for an exact address in Iowa City?
