How to have recipients submit their zipcodes so their results are linked to a geographic locations?
If you have not enabled the anonymous survey setting on your survey, SurveyGizmo does collect several pieces of Geodata including the Zip code of the respondent (this is all based on the IP address associated with the network that was being used when the response was submitted).
All of this information is available in an export of your survey responses (there will be columns for things like IP address, zip code, etc.).

You might bet faster results if you contact SurveyGizmo Support directly – https://community.surveygizmo.com/email-a-support-hero/
Also – probably not a good idea to post your phone number in a community forum.
