Narrative:

I intended to hand an air carrier X to R72 sector. Because of the close proximity of the number 7 and 4 on dsr keyboard I put the aircraft into handoff to R42. When I observed a radar handoff was accepted on air carrier X; I switched the aircraft to R72 frequency when in fact R42 had the handoff. The aircraft entered R72 sector as a limited data tag without a handoff. Air carrier X went over to R72 frequency but never checked on so R72 did not know about the aircraft. Several things could have helped stop this situation. 1) I could have taken notice of what sector the handoff went to. 2) R42 could have noticed they took a handoff not intended for them. 3) the pilot should have checked on R72 frequency so the controller could have told him he was on the wrong frequency and sent him back to me and I could have noticed R72 did not have a handoff yet. 4) what did cause it is the fact that R72 and R42 are in close proximity to each other; and the 7 and 4 on the dsr keyboard are easy to hit by accident when you mean to hit the other. Remedy ZDC management should be advised to change either R72 or R42 handoff numbers.

Title: ZDC CTLR EXPERIENCED OPDEV WHEN MAKING A HDOF TO THE WRONG SECTOR AND THE ACFT ENTERED AN ADJACENT SECTOR WITHOUT A HDOF.

Narrative: I INTENDED TO HAND AN ACR X TO R72 SECTOR. BECAUSE OF THE CLOSE PROX OF THE NUMBER 7 AND 4 ON DSR KEYBOARD I PUT THE ACFT INTO HDOF TO R42. WHEN I OBSERVED A RADAR HDOF WAS ACCEPTED ON ACR X; I SWITCHED THE ACFT TO R72 FREQ WHEN IN FACT R42 HAD THE HDOF. THE ACFT ENTERED R72 SECTOR AS A LIMITED DATA TAG WITHOUT A HDOF. ACR X WENT OVER TO R72 FREQ BUT NEVER CHKED ON SO R72 DID NOT KNOW ABOUT THE ACFT. SEVERAL THINGS COULD HAVE HELPED STOP THIS SITUATION. 1) I COULD HAVE TAKEN NOTICE OF WHAT SECTOR THE HDOF WENT TO. 2) R42 COULD HAVE NOTICED THEY TOOK A HDOF NOT INTENDED FOR THEM. 3) THE PLT SHOULD HAVE CHKED ON R72 FREQ SO THE CTLR COULD HAVE TOLD HIM HE WAS ON THE WRONG FREQ AND SENT HIM BACK TO ME AND I COULD HAVE NOTICED R72 DID NOT HAVE A HDOF YET. 4) WHAT DID CAUSE IT IS THE FACT THAT R72 AND R42 ARE IN CLOSE PROX TO EACH OTHER; AND THE 7 AND 4 ON THE DSR KEYBOARD ARE EASY TO HIT BY ACCIDENT WHEN YOU MEAN TO HIT THE OTHER. REMEDY ZDC MGMNT SHOULD BE ADVISED TO CHANGE EITHER R72 OR R42 HDOF NUMBERS.
