PF Interest

Hello Sir
Please help me for below query.
My Provident Fund contribution was 27 March 2018. Today I downloaded my passbook and found that the interest is updated till March 31, 2018. I was heard that the PF department pays interest till three years of resignation. If I am right then advise me what I should do.
Please clear my understanding.
Best Regards
Ashish

EPF annual interest calculation process is done usually in july every year and it is updated to all members and employers through sms by department

Last Interest was credited in my passbook , that is 31.03.2017. There are may employees in our company whose interest is not credit till date. I had marked some mails to PF but no any reply receive from them.

on submission of claim forms the department calculate for specific employee. but for desk work delay for all region, you have to visit the concerned Regional Provident fund commissioner desk
