My query is that can we issue them appointment letter now by mentioning their actual date of joining and on the existing company letter head?
or is there any other way to fulfill the compliance of joining date etc.
Request for your valuable advise regarding the same.

Is your management ready for this?
Whether workers ask for appointment letter?
Whether your establishment have same code under EPF & ESI althrough the changes of name?
If the reply is 'yes', you can go ahead with issue of letters but you have to give the details of employment for 2 companies that were existing prior to present one. All the respective letters are to be signed by your MD only.

Thanks for your valuable advise on the matter. The PF and ESI code is remain same for all the employees, in spite of changing the name of orgnaization.
Employee are not asking for any letter etc but on a safer side, my organization wants to close the loop.
So can we issue them appointment letter on existing company name letter ?
