Though a number of queries out there, all I have noticed are those that ultimately refer to an internal database that would have to be created and maintained as a solution.

I see that the USPS has a web based API set up and noted another called SmartyStreets (for some reason I associate them with the USPS), but the material goes right over my head.

Does anyone know of any developed procedures that would allow Excel to send query and receive results from resources such as these?

I recognize that I could easily have a huge disconnect here as though I know I can craft a call to the internet, I have no idea if I could receive a response somehow, but that's what makes this forum and you folks so great!

Best Regards,
