If you see a telephone number and are not sure what location it serves, you might want to look up the exchange number. In a 10-digit number, the fourth, fifth and sixth digits comprise the telephone exchange number, which is designated for a particular location. You can find a telephone exchange number by typing it into one of the free online databases. For example, a number with the area code "202" and the exchange number "456" is in Washington, D.C. Often you will also be able to see what telephone company services the exchange.
