In some places, nobody uses those CDP names, and they really shouldn't be on the map, but they're still going to show the error bubbles if you remove them.
Forget Zip Code maps. The USPS has consolidated so many towns and small cities into the nearest large city, they'll be useless.
Most of these that I've seen were caused by people adding city names outside of the city limits, where the No City box should be checked.

The reason for the city layer is to have accurate polygons to the city limits or edges of the CDPs.

The real problem is the town/township issue where in many places the individual towns within a township are better known than the township itself. But if political boundaries are that important, I guess I could just use official municipality names.
Does this also mean that all 5 boroughs of New York City should just say "New York?" That hardly sounds right in Queens, for example, where everyone commonly refers to the neighborhood names, including the post office?

In MD, much of the state is unincorporated. Zip codes boundaries are your best option there.
