Dear Vaidy,
You might have filled your account number in the withdrawal form as MH/xxxxx/yyyy. In this, MH denotes the state in which your PF account lies. 'xxxxx' denotes the establishment number, and 'yyyy' denotes your account number with the establishment where you have worked. After collecting the above details, you can browse epfindia.nic.in, where you can get the status of your claim under "KNOW YOUR CLAIM STATUS."
I hope this information helps you in checking the status of your PF claim at the Maharashtra EPF office. If you need further assistance, feel free to ask.
Best regards
