The exchange is the first three numbers and still is. In the past they were referred to as the HOBART 7 exchange, for example. Look at the way your telephone numbers are allocated. The numbers in a particular area share the first 3 numbers. If your hypothesis were correct then I would expect to see numbers like 554-3343 555-1111 and 556-3431 in the same area and you don't. The exchanges that served my area in Baltimore were 338, 467, 243, 235, and 889. Since this area was around JHU I would guess that the 467 is HOPKINS 7. I don't know about 235 but it may have been CENTRAL 5. -Ron PEnnsylvania 6-5000.
