I want to give feature to my users to search something in a specific postal code with in specific miles. Say for e.g. search cars in 98760 with in 30 miles radius.
From where can I get this database?
Thanks
1. google "zipcode database" and you will find plenty of commercial available db's for under $50.
2. the distance is a separate issue. You need to find a db with the longitude and latitude for each zipcode. Then, google for "longitude latitude distance formula" = you can use that formula to calculate the distance between any two zipcodes or to get a list of all zipcodes within x miles of a zipcode.
But I have found one containing both longitude and latitude which is used in calculating distance.
That's the way I 've done this in the past.
