At present there is no facility with epf to check your account balance on line.
you will get annual statement of your account through your employer
The statement of account will show the opening balance at the beginning of the period, amount contribution during the year, the total amount of interest credited at the end of the period or any withdrawal during the period and the closing balance at the end of the period.
any mistake in statement that can be apealed to RPFC through employer
