City name under Delivery settings

I think it would be helpful to not only have the zipcode but also the city name under delivery settings. From time to time I I may increase or decrease the delivery charge but am just staring at a list of zip codes but may not necessarily know what town corresponds to each code. I then have to open a 2nd window and google searchthe zip code in order to figure out what town that code belongs to. Having the names listed would simplify that routine maintenance.
