1. Approve the change through the owner, Members' Council, Board of Directors, or General Meeting of Shareholders, as applicable.
2. Prepare the relevant notice, resolution or decision, updated member/shareholder information, and supporting documents.
3. Submit the amendment electronically through the National Business Registration Portal or to the provincial business-registration authority.
4. Obtain the updated Enterprise Registration Certificate or confirmation of the registered change.
5. Update tax, banking, insurance, VNeID, e-invoicing, licenses, contracts, signs, and other affected records.

• Charter capital: register the new capital and ownership percentages. If the change follows a missed contribution deadline, register the amount actually contributed and make any required ownership adjustment. See capital contribution deadlines for the applicable timeframes and penalties.
• Business lines: submit a change notice and the relevant corporate resolution. For conditional or restricted sectors, confirm licensing, legal-capital, professional, or foreign-market-access requirements before starting the activity.
• Registered address: check zoning, office-use, tax-registration, and licensing requirements. If the move crosses a tax-administration jurisdiction, complete the tax-authority transfer or confirmation process before finalizing the enterprise-registration change.
• FDI companies: a change to the project location, investment capital, project objectives, or implementation scope may also require amendment of the Investment Registration Certificate, not only the ERC.
• Legal representative: the same registration procedure applies to a change of legal representative, subject to its own 10-day filing deadline.
