Dear,

A gazetted officer is one whose initial appointment is published in the official gazette of the government concerned. Usually it is group B and above. You can easily catch Gagetted officer in Electricity offices, Municipality offices, Revenue offices, District Collectorates, City Civil Courts, State Government Hospitals or any Central Government offices including the Railways. Character certificate can only be attested by Police record verification and Group A gazetted officer. For copies of original documents, both Group A and Group B officers can attest the documents.

Hope this helps!
