Updating FORM 5A in EPFO - changed our factory location from one place to another place

Need your guidance on updating form 5A in EPFO portal. We have changed our factory location from one place to another.
When I try to update Form 5A in EPFO portal, I get the following error message:
* PAN not getting verified
* Area pin code not able change
Our Concern is Proprietor

Please consult with PF department.
Or send me the details and I will do it. For further query, do not hesitate to contact with undersigned.

Same is the problem with me, PAN not verified.
What is the PIN area and how it is different from PIN code.
