After Renaming Your Company: 7 Key Things to Do

Short answer: After renaming a company, the enterprise must update consistently across its entire system: (1) make a new seal under the new name and destroy the old one; (2) update e-invoices and digital signatures; (3) notify the bank account; (4) adjust sectoral licenses (if they bear the name); (5) replace the signboard; (6) update contract templates, the website, and publications; (7) notify partners, customers, and the tax authority. Missing any step can cause transaction obstacles or invalid invoices. The company inherits all rights and obligations under the old name — contracts do not need to be re-signed.

Legal basis

• The Law on Enterprises 2020, as amended and supplemented by Law No. 76/2025/QH15 — provisions on registering a change of enterprise name; the principle of inheriting rights and obligations;
• Decree No. 168/2025/ND-CP on enterprise registration.

Checklist: 7 things to do after renaming

1. Make a new seal

Make a new seal under the new name; destroy/recall the old seal (prepare seal-destruction minutes); update the seal management and use regulations.

2. E-invoices and digital signatures

Update the new name on the e-invoice system; update digital signature information. An invoice bearing the old name after the renaming date is an invalid invoice — expenses may be disallowed and input tax not deductible.

3. Bank account

Notify the bank of the renaming; update the account holder’s name and the representative’s signature (if changed simultaneously).

4. Sectoral licenses

Licenses bearing the company name (conditional business licenses, eligibility certificates…) must undergo the name adjustment procedure under sectoral regulations.

5. Signboard

Replace the signboard at the head office, branches, representative offices, and business locations under the new name.

6. Contract templates, website, publications

Update the new name on: contract templates, quotations, the website, email, name cards, catalogues, product packaging…

7. Notify relevant parties

• Partners and customers: notify in writing of the renaming (with a copy of the new certificate) to align on payments and deliveries;
• Tax authority: update information (usually synced through enterprise registration, but should be checked);
• Social insurance: update the name of the employing unit.

Legal points to remember

• Inheritance: all rights, obligations, and contracts under the old name remain unchanged — no re-signing is needed;
• Tax code: unchanged;
• Transition timing: set an official date for using the new name and clearly notify all parties to avoid document confusion;
• Brand: if the new name is tied to a brand, register the corresponding trademark and domain names.

Frequently asked questions

What if the e-invoice update is forgotten?

An invoice issued under the old name after the renaming date risks being deemed invalid; invoices must be adjusted/replaced as prescribed and updated immediately.

Must each customer be notified of the renaming?

Regular partners and customers should be notified in writing (especially those with debts or long-term contracts) so payments and reconciliations are not disrupted.

Can the old seal still be used?

It should not be. After renaming, a new seal must be made and the old one destroyed; continuing to use the old-name seal causes confusion and legal risk.

Notes on applying current regulations

Many enterprises complete only the renaming on the license and forget to update invoices and the bank — only discovering the problem at payment or invoicing time. Prepare a checklist and complete it within 30 days after renaming. Contact an ANT Legal lawyer at 0966.475.966 for assistance.

Common risks to note
