C&P additions force changes in D.C. dialing

September 18, 1990|By Ross Hetrick | Ross Hetrick,Evening Sun Staff

Starting on Oct. 1, making a telephone call in the Washington metropolitan area will require an extra three digits if the call is being made across area code boundaries. The new arrangement also will change the first six numbers for the Defense Department from (202) 694 to (703) 614.

The change is being made to provide about 800 new telephone exchange numbers, which will allow the Chesapeake & Potomac Telephone companies in Maryland, Virginia and Washington to create hundreds of thousands of new numbers for the Washington area. The exchange is the first three digits of a seven-digit telephone number.

Currently, a caller in the Washington metropolitan area dials the basic seven-digit number to reach any number in Washington or its Virginia and Maryland suburbs. But starting next month, a caller must use 301 for Maryland suburbs, 703 for Virginia suburbs and 202 for Washington, if he is calling a number in a different area code.

For example, someone living in a Maryland suburb will have to use 202 to call Washington and 703 to call Virginia. Callers to the the Defense Department, which is in Virginia, will have to use the 703 code.

Despite use of area codes, calls in the Washington area will continue to be considered local calls and there will be no additional charges. For the local calls, it is not necessary to use 1 before the 10 digits, as is done with a long-distance call.

The change will also affect telephone customers in other parts of Maryland who have exchanges that work as if they were in Washington. If a person or business has such a number, they will also have to use the additional three numbers.
