What this page answers
This page answers a city-and-state ZIP-code query without pretending that the city has one universal code. It filters the active postal snapshot to the exact source place name Springfield and the state Missouri, groups the matching rows by ZIP code and keeps county or administrative labels visible. That method prevents same-name places in other states from being mixed into the answer.
Springfield is one of the most ambiguous US place names. This page is specifically the Missouri result and never combines records from Illinois, Ohio or other states.
How to choose the correct code
Start with the recipient’s full address rather than choosing a code solely because it appears under the city name. Compare the street, unit, county or area label, and any postal-operator result available to you. A code can serve several place descriptions, and a city name used for mailing can differ from a legal municipality. Open the linked postal result to see every active record sharing that country-and-code pair.
Preserve leading zeroes and store ZIP codes as text. Do not calculate or fill a missing code from nearby coordinates. If the address is important for shipping, billing, identity or compliance, confirm it with the recipient or the relevant postal operator.
What the source statistics mean
The unique-code count is calculated from the active imported snapshot, while the record count includes every matching place row. County or area labels are displayed as supplied and can be absent. The coordinate count reports source rows with numeric coordinates; those points are useful for approximate nearby exploration but are not official postal polygons or property locations.
Snapshot totals can change after a new GeoNames import. The visible source date and correction route make the result auditable. ZipCodeGlobe preserves raw values separately from normalized search text and never collapses a shared ZIP code to one arbitrary location.
Useful next steps
After selecting a code, open the full result, compare nearby codes, calculate distance to another postal code or review the United States address-format reference. The guided finder is useful when you know the state and city but need to narrow a list. Related city guides below provide a natural next step without placing thousands of repetitive links in the footer.
Limits of a ZIP-code city guide
This page does not establish city limits, tax jurisdiction, voting districts, school zones, emergency coverage or proof of residence. Postal routing geography and government boundaries serve different purposes. It also does not certify deliverability to a street, building, apartment, business or recipient. Use the page as a transparent lookup and research aid, then consult the authoritative service for decisions requiring official boundaries or current delivery confirmation.
