Dear Pooja ji,
Your question is how to change company name in PF and ESI office?
I myself and some more members gave you appropriate answer.
If your question is how to change company name? My answer to it, is as under:
In case of proprietary firm or partnership firm, change of name means saperate entity. You need to obtain fresh registration with PF, ESI, PT, LWF, Factory Licence etc. Also with service Tax, sales Tax, VAT etc.
In case of Private Limited or Limited Company, name change can be obtained by making an application to ROC by adopting due procedure under the Company Act and obtaining fresh certificate of incorporation upon change of name.
Name change on account of mergers and acquisition, on the basis of order by respective HCs apply to ROC and obtain fresh certificate of incorporation.
Intimation of change of name so done, shall be given to all the concern authorities with supporting. You need to get endorsement or fresh certificate upon this change. Additionally, you need to submit prescribed Form, if any by any authority, e.g. EPF.
Some of the members opened out this subject in this thread by you, so I thought of giving clear and correct answer to you and viewers.
