USPS Not Offering Shipping Options To Locations within Store Zone

[rodeospot]

I am in dire need of help with the Shipping Module for USPS. USPS told me we are on the production server, my store is setup, Anyone trying to purchase items from my client's store, with the same zip code as my client's store, do not get the USPS Shipping option at checkout. I can use my address in a different state I get all the options. I setup a test account with the same zip code as the store's, and only get a flat rate shipping option, nothing from USPS. This is the first time I have ever running into this. Any help would be greatly appreciated. I have been researching solutions for days to no avail. THANK YOU!! I have installed the latest USPS Shipping Module, USPS_2018_03_28_K10

Do you have your Modules->Shipping->usps configured to use a "Shipping Zone"?
