The badge has been awarded 64 years after the war ended in Europe
Some 9,000 former workers at the top secret Bletchley Park station have received recognition for their efforts cracking enemy codes during WWII.
The secret army of men and women have been given an award known as the Bletchley Park Commemorative Badge.
Veterans who are no longer alive will be commemorated by a Roll of Honour, to be put on display at Bletchley Park, Buckinghamshire.
"We were all proud of what we were doing," said recipient Jean Whitney.
The awards were given out at Bletchley Park's modern replacement, GCHQ in Cheltenham, Gloucestershire.
Some of Britain's best brains spent the war cracking enemy codes at Bletchley Park, with some historians suggesting their efforts shortened the war by two years.
The codebreakers' success allowed the Allies to know in advance what German forces were planning.
