Changing your GST registration? OTP verification is now a must (GSTN Advisory 686)

GSTN has issued Advisory No. 686 (1 November 2026) on a revised process for amending GST registration in FORM GST REG-14. It follows Notification No. 05/2026-Central Tax dated 26 October 2026, which replaced the Rule 19 provisions on amendment of registration in the CGST Rules, 2017. The new process applies from 1 November 2026.

What has changed

• OTP verification is mandatory. The mobile number and email of the Primary Authorised Signatory and of one selected promoter, partner, director, Karta, member or trustee must be verified by OTP.
• 3-day window. The OTP verification has to be completed within 3 days of submitting the application. If it is not done, the ARN will not be generated and the amendment does not go through.
• Online checks. PAN, DIN and CIN, wherever applicable, are validated online before the ARN is generated.
• Faster approval for most changes. Amendments other than the principal place of business (for example legal name, adding or removing partners or directors, additional places of business) stand amended once the online verification and validations are completed. A change of principal place of business is still examined by the proper officer.

Reports differ slightly on exactly which kinds of amendment need the OTP step, so check the advisory on the GST portal before you file.

What to do

• Before filing REG-14, make sure the signatory and the promoter or director whose details you select have their registered mobile and email at hand.
• Complete the OTP step the same day, from Services > Registration > OTP verification of GSTIN on the GST portal.
