Vietnam Corporate Seal: Rules, Management and Legal Use

Vietnam Corporate Seal: Rules, Management and Legal Use in 2026

Introduction

A Vietnam corporate seal remains an important part of company administration and document control. However, Vietnam’s corporate seal framework has changed significantly compared with older business practices.

Today, enterprises have greater flexibility over their seals. Therefore, companies should focus not only on whether a document carries a physical stamp, but also on who has authority to sign, approve and use company documents.

For foreign investors, understanding these rules is particularly important. A clear seal-management process can reduce operational risks and support stronger corporate governance.

What Is a Vietnam Corporate Seal?

A Vietnam corporate seal, also called a company seal or corporate stamp, provides an authentication tool for company documents and records.

Traditionally, physical company stamps played a central role in Vietnamese business transactions. However, modern Vietnamese corporate law gives enterprises more freedom to determine how they design, manage and use their seals.

In practice, a company may use a physical seal, an electronic seal or other appropriate authentication methods, depending on the transaction and applicable requirements.

Therefore, companies should establish clear internal rules before employees use the corporate seal.

Is a Corporate Seal Mandatory in Vietnam?

Vietnamese enterprises do not generally need to use a physical corporate seal on every business document.

Under the current enterprise-law framework, an enterprise decides the type, quantity, form and content of its seals. The company also manages and stores its seals according to its charter or internal regulations.

Therefore, the absence of a physical stamp does not automatically make a business document invalid.

Instead, companies should examine the applicable law, transaction requirements and authority of the person signing the document.

For the current legal framework, businesses should review the Law on Enterprises and its subsequent amendments.

Who Decides the Vietnam Corporate Seal?

The enterprise generally has the authority to determine its corporate seal arrangements.

Depending on the company’s charter and internal governance structure, the competent corporate body may decide:

The number of company seals
The form and design of the seal
The information shown on the seal
Who has custody of the seal
Who may use the seal
When employees may use the seal
How employees should record seal usage
How the company should replace or cancel a seal

Therefore, companies should document these rules clearly.

For larger businesses, a written seal-management policy can help separate signing authority from physical seal custody.

What Can a Vietnam Company Seal Contain?

A company has considerable flexibility when determining the form and content of its seal.

A corporate seal may identify the company through information such as:

Company name
Enterprise identification information
Other information approved under internal company procedures

However, businesses should avoid designs that could create confusion with another company’s identity or cause uncertainty during official transactions.

Furthermore, companies should maintain consistency between the information shown on their seal and their official corporate records.

How Should a Vietnam Corporate Seal Be Managed?

Effective seal management represents an important internal-control function.

Companies should establish clear procedures covering custody, approval, usage and record keeping.

1. Define Seal Custody

The company should appoint a responsible person or department to keep the physical seal.

For example, the company may assign custody to:

Corporate administration
Legal and compliance
Finance and accounting
A designated company officer

However, the person holding the seal should not automatically receive unlimited authority to approve documents.

2. Establish Approval Procedures

Before applying a seal, the responsible team should confirm that the document has received the necessary review and approval.

A practical approval process may include:

Document preparation
Legal or commercial review
Management approval
Signature by an authorized person
Seal application where appropriate
Record keeping

Therefore, the seal should form part of a broader document-control system.

3. Keep Seal-Use Records

Companies should consider maintaining a seal-use register for important documents.

The register may record:

Date of use
Document title
Responsible department
Approving person
Signatory
Purpose of the seal
Filing date

As a result, the company can investigate unauthorized or incorrect seal use more efficiently.

4. Protect the Physical Seal

Companies should store the physical seal securely.

In addition, management should limit access to authorized personnel. Companies should never leave the seal in an unsecured location where employees or third parties can access it without approval.

5. Protect Digital Credentials

If the company uses digital signatures or electronic authentication, management should apply the same security principles.

Companies should protect digital signing credentials with appropriate access controls. Furthermore, employees should never share passwords or authentication devices without proper authorization.

When Is a Vietnam Corporate Seal Used?

Companies may use a corporate seal for different types of corporate and commercial documents.

Depending on the transaction, examples may include:

Contracts
Corporate resolutions
Internal decisions
Authorization documents
Administrative documents
Banking documentation
Tax-related documentation
Employment records
Commercial correspondence

However, the need for a physical seal depends on the specific document and applicable requirements.

Therefore, companies should not automatically stamp every document simply because it represents a company document.

Does Every Contract Need a Company Stamp in Vietnam?

No general rule requires every commercial contract to carry a physical company stamp.

Instead, businesses should examine:

Applicable contract law
Industry-specific regulations
Contract terms
Counterparty requirements
Signing authority
Internal corporate procedures

For this reason, companies should distinguish between signature authority and seal authority.

A person may properly sign a document without applying a physical company seal when the applicable legal and contractual requirements do not require one.

Corporate Seal vs Digital Signature in Vietnam

A physical corporate seal and a digital signature do not necessarily perform the same function in every situation.

A physical seal traditionally supports corporate document authentication. By contrast, a digital signature provides an electronic authentication mechanism for digital transactions.

Digital signatures are increasingly important for:

Tax filings
Electronic invoices
Online government procedures
Digital contracts
Electronic business transactions

Furthermore, digital signing can improve document traceability and reduce paper-based administration.

Who Should Keep the Vietnam Company Seal?

The company should determine seal custody through its charter or internal regulations.

In practice, the responsible person should have clearly defined duties.

For example, the company may establish rules covering:

Who can request seal use
Who approves seal use
Who physically applies the seal
Who records seal usage
Who stores the seal
What happens outside normal working hours
What happens when the custodian leaves the company

Consequently, companies can reduce the risk of unauthorized use.

What Happens If a Company Loses Its Seal?

A lost corporate seal creates an internal security and compliance concern.

The company should promptly assess:

Whether someone could misuse the seal
Which documents could face a risk
Whether management should notify relevant parties
Whether counterparties require notification
Whether the company needs a replacement seal
Whether the company should strengthen internal procedures

Furthermore, management should document the incident and preserve relevant evidence.

The appropriate response may depend on the company’s seal arrangements and the circumstances of the loss.

Can a Vietnam Company Change Its Corporate Seal?

Yes. Vietnamese companies have flexibility regarding their seal arrangements.

A company may change its seal because of:

Rebranding
Corporate restructuring
Changes to company information
Internal governance changes
Loss or damage
Security concerns
Operational requirements

However, before adopting a replacement seal, the company should review its internal regulations and identify documents or counterparties that may require updates.

Do Companies Still Need to Register Their Seal Specimen?

Older Vietnamese company procedures involved formal notification of seal specimens to authorities.

However, the current enterprise-law framework gives enterprises greater control over their seals.

Therefore, companies should avoid relying on outdated instructions designed for the previous regulatory system.

For current legislative developments, businesses should review the amended enterprise-law framework, including Law No. 76/2025/QH15.

Vietnam Corporate Seal Rules for Foreign-Owned Companies

Foreign-owned companies generally follow the same core enterprise-law framework regarding corporate seals.

Nevertheless, foreign investors should pay particular attention to internal governance.

For example, a foreign-owned company may have:

Overseas directors
Local authorized representatives
Regional management teams
External accounting providers
Local legal representatives
Multiple offices

As a result, seal custody can become more complicated.

A written authorization and seal-management procedure can help ensure that local employees understand exactly when they may use the company seal.

Common Vietnam Corporate Seal Mistakes

Mistake 1: Assuming Every Document Needs a Physical Stamp

Some companies continue to stamp every document because of historical business practices.

However, this approach can create unnecessary administrative work.

Mistake 2: Giving Too Many People Access

Allowing many employees to access the company seal can increase control risks.

Instead, management should restrict access according to clearly defined responsibilities.

Mistake 3: Failing to Define Approval Authority

A seal should not replace proper management approval.

Therefore, companies should establish who can approve and sign documents before employees apply the seal.

Mistake 4: Ignoring Internal Regulations

A company may have flexibility regarding its seal, but internal rules still matter.

Consequently, employees should understand and follow the company’s charter and seal-management procedures.

Mistake 5: Using Outdated Legal Information

Vietnam’s corporate regulatory environment continues to evolve.

For this reason, businesses should verify current legislation rather than rely on old guidance about seal registration or notification.

Mistake 6: Confusing Seal Use With Signing Authority

A person who physically controls the seal does not necessarily have authority to sign contracts.

Similarly, a person authorized to sign a document may not manage the physical seal.

Companies should therefore separate these functions where appropriate.

Best Practices for Managing a Vietnam Corporate Seal

A practical corporate seal policy should cover the entire document lifecycle.

Companies should consider the following measures:

Assign a designated seal custodian
Establish written approval procedures
Separate signing and seal custody functions
Keep records of important seal usage
Restrict physical access
Protect digital signing credentials
Review authorization arrangements regularly
Update internal rules when the company changes
Train relevant employees
Review applicable legal requirements periodically

Furthermore, foreign-owned companies should ensure that their Vietnam operations follow local requirements and the group’s internal compliance standards.

Why Vietnam Corporate Seal Management Matters

A Vietnam corporate seal represents only one part of a company’s document-control system.

However, poor seal management can create unnecessary operational and compliance risks.

Therefore, businesses should combine seal procedures with clear signing authority, document approval, internal controls and digital-security measures.

For foreign investors, these controls become even more important when decision-makers operate outside Vietnam.

By establishing clear responsibilities from the beginning, a company can reduce confusion and improve the reliability of its corporate administration.
