I understand that your chain of institutions is not aided by the government but is purely self-financed private educational institutions. If so, each center should have separate registrations as per the State Shops and Commercial Establishments Act under the relevant Labour Offices. If you disburse salary centralized from one place, you can have a centralized PF registration. Your establishment will also be covered by the ESI Act for which the main office shall have to obtain registration, and the centers will have to take sub-codes based on this registration. Moreover, your establishment will be covered by all other Labor Acts like the Payment of Wages Act (which provides for payment of salaries within a specified time), Payment of Gratuity Act (provides for payment of gratuity to those who leave the organization after serving for 5 years), Maternity Benefit Act (provides for granting leave with salary for 12 weeks, etc., to women employees for delivery), Industrial Disputes Act (provides for the settlement of disputes), etc.
Steps to Begin Compliance
To start with, registration under the Shops Act, Employees' Provident Fund and Miscellaneous Provisions Act, and ESI Act are to be carried out. Besides, you have to obtain a license to run a business or profession from the Municipal Corporations/Panchayats following the Municipalities Act also.
