Five Ames place-name ZIPs, one county
Iowa State University anchors Ames in Story County. The five ZIP rows DialWick shows for that place name all come from GeoNames' US postal-code export (CC BY 4.0), retrieved 2026-08-03, not from a live scrape of USPS's web lookup form.
For the exact place string Ames in Iowa, that export yields five rows. All five say Story County. There is no GeoNames county split of the kind you see on multi-county city pages in other DialWick ZIP guides.
Iowa's Department of Public Safety NIBRS ZIP appendix lists the same five codes under Ames / Story and marks 50010 and 50014 as Standard and 50011, 50012, and 50013 as Unique [Iowa DPS NIBRS ZIP appendix, checked 2026-10-25]. zip-codes.com likewise labels 50011-50013 as unique Iowa State University codes and puts the city in Story County with area code 515 [zip-codes.com: Ames, IA, data note read 2026-10-25].
Iowa's Department of Public Safety ZIP reference marks 50010 and 50014 as Standard and 50011-50013 as Unique. Unique rows usually mean a large single recipient such as a university mail plant, so only use those three when the recipient prints them.
Commercial city pages sometimes list aliases or nearby codes GeoNames does not attach to the primary label Ames. This guide stays on the five primary rows; anything outside 50010-50014 needs a USPS lookup before it goes on a label.

Standard street ZIPs vs university unique codes
If you are filling a shipping form for a house or apartment in Ames, 50010 and 50014 are the usual street-delivery codes in public directories. 50011, 50012, and 50013 exist as unique assignments associated with Iowa State University mail; they still carry the Ames place name in GeoNames, but they are not interchangeable neighborhood street ZIPs.
Some commercial pages also list 51108 under an Ames heading with an alias such as James. That code does not appear as an Ames primary place-name row in the GeoNames extract used here, so it is left off this table on purpose.
There is no single "main" Ames ZIP that covers every address. Match the five digits printed on the mail piece rather than guessing from a campus or downtown landmark.
Street mail for ordinary Ames houses and apartments usually lands on 50010 or 50014. Campus departments and residence halls explain why Unique codes sit beside the city name in public directories.
Do not infer a campus code from a building nickname. ISU mail instructions and the recipient's letterhead beat a color-coded ZIP map. Putting a Unique code on a Standard street address is a common form reject.
Population and alias columns on commercial sites refresh on their own schedule. DialWick's county column stays pinned to the 2026-08-03 GeoNames extract. If a commercial page disagrees on county, prefer GeoNames here and re-check USPS for delivery type.
For tax, banking, or shipping forms, copy the ZIP from recent mail to that address. Marketing names for neighborhoods are not postal authorities.
Area code 515 is separate from the ZIP list
Telephone numbering and postal codes are different systems. DialWick's area-code dataset (compiled from the public North American Numbering Plan area-code list, retrieved 2026-08-03) places code 515 in Iowa and names Ames among the communities it covers, alongside Des Moines and other north-central Iowa towns. The record notes a 2000 split that created 641.
A ZIP change does not move your area code, and an area-code overlay does not rewrite postal routes. For the ZIP-versus-NPA distinction in general, see ZIP code vs area code.
For other city ZIP tables built the same way, see Boynton Beach ZIP codes and Charleston WV ZIP codes.
A ZIP change does not retune a phone number. Mail sorting and call routing use different maps. Use DialWick's 515 pages when you only need the phone side.
Other Story County place-name lists in other DialWick ZIP guides share the same GeoNames pull. For ZIP versus other countries' postal codes in general, see postal code vs ZIP code.
