[edit] history of 510
Telegraphy#Telex states the following:
TWX had special area codes: 510, 610, 710, 810 and 910. With the demise of TWX service, these codes were re-provisioned as standard geographic NPAs in the 1990s.
Can anyone add a history section for this area code? —Preceding unsigned comment added by 65.42.230.51 (talk) 23:14, 8 September 2007 (UTC)
