CDA, Guwahati was established at Guwahati in deference to the request of the GOC-in-C Eastern Command, Calcutta on 15th July, 1983(AN). CDA Guwahati was set up with a tentative charter of serving as a LIAISON CELL and Financial Advice Agency for the ARMY and Border Roads Units in this area under CDA, PATNA with a nucleus staff serving at North Eastern States and Bhutan. CDA Guwahati had to expand its activities in the light of periodical discussion with HQrs Office. The evolution of Main Office of CDA Guwahati from 15.07.1983 to its growth into a full fledged regional CDA is as follows. With the assumption of work relating to Accounts Section and Store Audit Section form 1st April 1986, CDA Guwahati functions as full-fledged Regional CDA as Financial Advisor to the GOC-in-C Eastern Command and the Formation Commanders as well as Border Road Organization, Units/Establishments located in Assam, Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland and Tripura as well as Bhutan.
