How to Change Mobile Number on GST Portal?

Mobile number on the GST portal holds a very significant value since it's the major point of contact between the authorities and the registered person. All the communication, notifications, and updates issued by the department regarding the GST portal are intimated to the concerned person through a mobile number. Thus, it is always advisable to update the GST portal immediately with the current working mobile number in case of any changes.

Key considerations:

• First of all, it's important to ascertain whether changes are to be carried in “Core-Field '' or “Non-Core Field.” Any sort of alternations in Email ID, phone number, or bank details are part of the non-core field.
• Further, any changes carried out by taxpayers after the GST registration are classified as “Amendment of Registration” under GST.

In this article, you can find the entire process of how to change the mobile number on the GST portal. There are basically two ways of carrying out the changes depending on the situation, that is,
