Answer 1

You can use geonames zip code search . For example:

http://ws.geonames.org/postalCodeSearch?adminCode1=CA&placename=San+Francisco&maxRows=3

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<geonames>
<totalResultsCount>76</totalResultsCount>
<code>
<postalcode>94102</postalcode>
<name>San Francisco</name>
<countryCode>US</countryCode>
<lat>37.781334</lat>
<lng>-122.416728</lng>
<adminCode1>CA</adminCode1>

<adminName1>California</adminName1>
<adminCode2>075</adminCode2>
<adminName2>San Francisco</adminName2>
<adminCode3/>
<adminName3/>
</code>
<code>
<postalcode>94103</postalcode>
<name>San Francisco</name>
<countryCode>US</countryCode>
<lat>37.77254</lat>

<lng>-122.414664</lng>
<adminCode1>CA</adminCode1>
<adminName1>California</adminName1>
<adminCode2>075</adminCode2>
<adminName2>San Francisco</adminName2>
<adminCode3/>
<adminName3/>
</code>
<code>
<postalcode>94107</postalcode>
<name>San Francisco</name>

<countryCode>US</countryCode>
<lat>37.762147</lat>
<lng>-122.397099</lng>
<adminCode1>CA</adminCode1>
<adminName1>California</adminName1>
<adminCode2>075</adminCode2>
<adminName2>San Francisco</adminName2>
<adminCode3/>
<adminName3/>

<ZipCodeLookupResponse>
