Issue with coordinates on zipcode 80226 Lakewood CO #3

Closed jlariza closed 4 years ago

jlariza commented 5 years ago

Good day,

I am using the library to get the coordinates of a zipcode and retrieve the closest location from a database.

I'm having an issue with zipcode 80226 for Lakewood, CO. Its coordinates are incorrect and it is generating problems.

This is the output I get:

zip_info = zipcodes.matching("80226")
[{'active': True,
  'city': 'DENVER',
  'country': 'US',
  'lat': 39.76,
  'long': -104.87,
  'state': 'CO',
  'world_region': 'NA',
  'zip_code': '80226',
  'zip_code_type': 'STANDARD'}]

But when I get that point on google maps, I am getting a point 12 miles further than Lakewood.

Could you please check if the zipcodes database are updated and correct?

Thank you,

Hello @jlariza,

The zipcodes data file used in this project was compiled from the free version of the zipcode information packaged provided here. As stated within the free version of the download, the coordinate information is approximate and is not precise (this is an intentional feature of the free version).

I apologize for the trouble caused, however no fix can be made unless a free data source is provided with precise coordinate data.

In the latest version, I have used a different, freely-available zipcode database to provide hopefully more accurate GPS coordinates. Please let me know if you continue to have issues. Thanks!
