All of Delaware (area 302) falls into one of 3 calling areas: Newark (NOT Wilmington, which misses 378 in Middletown) Dover Georgetown Area 301 (Maryland): In the northeastern area, Elkton is local to all of Cecil County except the 658 prefix in Rising Sun, the only Maryland prefix not directly under C&P. Bel Air is local to all of Harford County AND some suburbs bordering on Baltimore city. I believe Towson is local to all of Baltimore County (I know it's local to Baltimore city). Also notice that in general, phone prefixes can cross county lines. I was just in Ellicott City, Maryland in Howard County (prefixes 461 and 465 in area 301), and noticed that the phone prefixes and the zipcode both pick up a neighboring part of Baltimore County. In Delaware, 653 Smyrna is mostly in Kent County but picks up a little bit of New Castle County, and nearby in 215 in Pennsylvania, 388 Menden- hall is mostly in Chester County but picks up a little bit of Delaware County.
