Hello,
I'm looking to make some online searches by zipcode but they have a 50
mile radious limit.
I want to cover the entire USA, so I need a list of zipcodes that
would cover me the entire USA.
Minor overlaps is fine.
If the price is too low, please tell me and I'll pay a bit more, I
have no clue on how much something like this would take.
thanks |

Have you tried using the Google Local search?
You can find it at:
local.google.com
Search on the topic of your choice, and enter an address or zip code
to narrow down to a particular city or area.
When you get results, up in the right hand corner of the page is an option for:
"Search within: 1 mile - 5 miles - 15 miles - 45 miles"
Just pick 45 miles, and you'll have pretty much the radius you're looking for.
Let me know if that works for you, and if it doesn't, perhaps you can
let us know in a bit more detail what you need.
Thanks,
pafalafa-ga

Hello All,
Thank you for your responses, I'd like to clarify the question so we
all understand the exact objective.
Let me explain with an example,
1. Imagine I wish to know all the address for all the Wal-Mart Stores in the us.
2. Imagine on the Wal-Mart website a "Store Locator" that let's you
search by zip code for up to a 50 miles radius.
3. What I came to google.answers is to find the list of zip codes that
if I search this list of zip codes on the Wal-Mart site, I will get
ALL their store address.
Now, please do not send me links to all Wal-Mart stores, because this
is just an example of what I need for.
thank you so much

I'm still not sure I get what you're after 100%, but let's stick with
the WalMart example and see where we wind up.
Take a look at this link:
http://local.google.com/local?num=100&hl=en&lr=&c2coff=1&safe=off&sa=G&near=20016&sc=1&q=category:+Wal-Mart+Stores
It's all the WalMart locations (just an example!) within a 45 mile
radius of my house, showing their address and zip code, along with
other information.
Is this the sort of thing you're after?

hello pafalafa-ga,
Well, the list from your URL is good, so to work further with the
walmart example, all I still need now is a list of us zipcodes to
search on google.local to get me ALL the walmart stores in the US.
So again, I need a list of zipcodes that would cover the whole US in
clusters of 50 miles.
I was envisioning that someone can take a US map, draw circle of 50
miles, and get the zipcodes of the centers of each circle.
Again I wish to say that if this requires alot more work then I
thought, I will add more money to the price.
thanks

Hello,
Thanks for the feedback.
I don't know of a source where you can get the precise information you
asked for -- 50 circles of the US based on zip codes. And frankly, I
don't think such a source exists, and would be very difficult to
actually create, given the wild way that zip code boundaries are
shaped.
An alternative approach might be to make use of 3-digit zip code maps
as a rouch approximation. The 3-digit zones tend to have areas
roughly in line with a 50-mile radius requirement, though in dense
population zones this rule of thumb doesn't really hold.
Take a look at the 3-digit map of NY state and let me know what you think:

Hi,
Just throwing another thought into this to help. To take your map and
circle example; we would need a list of the zipcodes (some how in some
form) to center our circle on, and create the lists with. So if it
were WalMarts we are looking for, this gives us the list of zip codes
to start with.
I have (just for conversation sake), a complete list of all the
zipcodes in the US, with city and states. That part is easy, as you
know.
The post office doesn't parse the zipcodes by square miles or blocks
or anything else (not even by state lines which is why the US Census
doesn't use zip codes). They have their own methods of deciding when
and where new post offices are placed. They are also not meticulous
about having the zip codes in numerical order for square mile area, or
we could use the idea of getting the store's zipcode and then the ten
before it and the ten after it ( or something like that).
The only idea I have really is to use the Google API to query for each
"location" zipcode, as pafalafa-ga has shown, then parse the results
for zip codes and create the list from those sets. That could take
awhile since there is a limit to how many queries you can do per day
using the Google API. We could use a few other sources if we got
creative. Nevertheless, there is going to be script writing involved
and some creative thought in getting the result you are looking for.
So, yes, I'm thinking your current bid is not going to cover the work
involved in getting this list for you, and my current thinking/ideas
would also require a list of the zip codes for the center of the
circles, or a list of the "WalMarts" we are looking for.
