20miles的公司信息等， e.g.Distance: 16.21 miles 。。。
怎么实现的？有什么免费或付费的网络服务吗？
谢谢！ |

you need to purchase a zipcode database. zipcodeworld.com has one, and you
can also integrate their API. |

I found out that myvisajobs.com also has the similar but simpler feature.
Who is the owner of it? Can you give me suggestions? Thanks. |

But, I think you need to purchase a database/subscription service. |

这些zipcode对应经纬度。假设地球是个球体，用立体几何解对应的弧长。No big deal.
