I needed sample ZIP codes from all 50 states, so that I could test a website feature I’ve been working on. There are many sites that allow you to look up a ZIP code by city and state, but I was looking for a quick reference all on one page.
I couldn’t find one right away, so I built my own. I thought it may be useful to someone else, so I’m posting it here.
[Update, 11-Dec-2014: When I posted this initially, I accidentally transposed the ZIP codes for Annapolis, MD, and Boston, MA. I have fixed that now.]

i need zip codes by states and cities
I haven’t needed that kind of detail, but it looks like there are a lot of options for downloading complete ZIP code listings. I searched for “usps zip code file”, and found several, both free and paid products like this one, https://www.aggdata.com/free/united-states-zip-codes
Thank you for saving me an hour of work!
Thank you, I use this everyday for testing different states at work.
Again. Thank you so much for this.
Very helpful, thanks for doing this. Used for a UPS pricing test, saved me a lot of time. 🙂
Thank you
This was FANTASTICALLY helpful for a search on states with a specific energy provider. Thank you for saving me about a hundred clicks and three hours’ time.
I have a customer who wanted average freight rates to each of the lower 48 states. I was able to use this list to pick cities, instead of having to find them all on my own. Thanks!!
