Provisions
Rule 138, CGST Rules 2017; GSTN advisory on multi-factor authentication, 2025
Analysis
If the OTP goes to an old number, update the mobile number in your GST registration first, and the e-way bill portal picks it up. Example: an accountant who left the firm still has the registered mobile; you cannot log in. Update authorised signatory details through a non-core amendment on the GST portal, then try again. You can also create sub-users for staff.
