Sir, appropriate Branch Office of ESIC to which the insured person is attached is the appropriate authority/office to make corrections etc. in names of insured persons, dependants, family members etc. Therefore, it is better to contact the said office. However, in case needful is not done by the Branch Office Manager, the issue can be raised either telephonically or through e-mail or personally with the Branch Officer of Benefit Branch at the appropriate Regional/Sub-Regional Office of ESIC.
