Confirm the enterprise constitution. Proprietorship, partnership, company and other forms link identity differently.
Compare PAN and GST records. Fix the government source record first if the legal name or identifier is wrong there.
Use the official Udyam update route. Keep the Udyam number and acknowledgement; do not file a second registration for the same enterprise.
Save screenshots and references. Record the error before and after each correction attempt.
Escalate through the official grievance channel. Avoid look-alike sites or agents charging for a guaranteed correction.
Decision rule: one enterprise should not create duplicate registrations merely to hide a data mismatch. Repair the identity chain instead.
