IDEA: Take highlighted address and add +4 to zip code

[dpupello]

Can someone whip up a program or AHK script that would take a highlighted address, such as:

123 Main Street, Anyville, ST 55555
or...

123 Main Street
Anyville, ST 55555

...and "lookup" the Plus 4 zip code, so that it would return:

123 Main Street
Anyville, ST 55555-1234

or

123 Main Street, Anyville, ST 55555-1234

...depending on the input format.  Even just returning the Plus 4 code (1234) to the clipboard might also be useful.  Would beat the hell out of going to the USPS +4 lookup web page, then individually typing/pasting in the pieces of the address, then clicking "LOOKUP", etc.

Thanks for consideration!

This is the only thing I found that seemed close. I don't know what Yahoo Widget Engine is though:

If I or someone can find me a text file listing of 9-digit zip codes with associated city and state, I can easily do this. I found this webpage but it's only got 5-digit zip codes. Using a CSV text listing, this coding snack would be a piece of cake.

I might be able to leverage the USPS website itself.  Hang tight...

Here's a quick'n'dirty proof of concept:

Please let me know if it works for you.
