The artifact-by-artifact lookup follows below. | Evidence area | Documents needed | | ---------------------- | ------------------------------------------------------------------------------- | | Legal Registration | Giấy chứng nhận đăng ký doanh nghiệp | | Constitutive Documents | Điều lệ công ty | | Tax Registration | *Any one of:* Giấy chứng nhận đăng ký thuế · MST confirmation | | Operating Permit | Giấy phép kinh doanh | | Ownership Records | *Any one of:* Danh sách Thành Viên · Danh sách Cổ đông Sáng lập | | Governance Records | *Any one of:* Danh sách thành viên HĐQT · HĐTV và người đại diện theo pháp luật | | Signing Authority | *Any one of:* Nghị quyết · Quyết định Ủy quyền | | Address | *Any one of:* Hợp đồng thuê · Hóa đơn dịch vụ · Sao kê ngân hàng | | Good Standing | Giấy chứng nhận đăng ký doanh nghiệp | ## Documents to collect The physical documents you'll collect from your customer, with the evidence area each one proves. One document can prove multiple areas — for example, Brazil's Cartão CNPJ covers both tax and business-registration proof, so it appears once with both areas listed. | Document | Proves | | ---------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ | | **Giấy chứng nhận đăng ký doanh nghiệp (ERC)** | Legal Registration, Good Standing | | **Điều lệ công ty (Company Charter)** | Constitutive Documents | | **Giấy chứng nhận đăng ký thuế** | Tax Registration | | **MST confirmation** | Tax Registration | | **Giấy phép kinh doanh (Business License)** | Operating Permit | | **Danh sách Thành Viên** | Ownership Records | | **Danh sách Cổ đông Sáng lập** | Ownership Records | | **Danh sách thành viên HĐQT** | Governance Records | | **HĐTV và người đại diện theo pháp luật (Director/Council list on ERC + Charter)** | Governance Records | | **Nghị quyết** | Signing Authority | | **Quyết định Ủy quyền** | Signing Authority | | **Hợp đồng thuê** | Address | | **Hóa đơn dịch vụ (trong vòng 90 ngày)** | Address | | **Sao kê ngân hàng (trong vòng 90 ngày)** | Address | | **Sector-Specific License** | SBV — State Bank of Vietnam (banking/payments), SSC — State Securities Commission, MoF / ISA — Insurance Supervisory Authority | ### Collection notes * **Legal Registration:** Issued by DPI; carries enterprise code = tax code. For FIEs, also collect IRC. Verify current status at dangkykinhdoanh.gov.vn. * **Constitutive Documents:** Filed with DPI at incorporation; amendments must be re-filed. Single constitutive document covering capital, governance, and representative authority. * **Tax Registration:** GDT issues; since 2010 unification, ERC itself displays the enterprise code = tax code. Standalone tax certificate or GDT portal printout accepted. * **Operating Permit:** Issued by provincial or district People's Committee. Annual business license fee abolished from January 2026; the license document itself remains required where applicable. * **Sector-Specific License:** Required only for regulated-sector entities. * **Ownership Records:** For LLC entities collect the members list (Danh sách thành viên); for JSC entities collect the founding shareholders list (Danh sách cổ đông sáng lập). Current shareholder registers are company-maintained documents. * **Governance Records:** ERC names legal representative(s); charter or filed resolution lists Members' Council (LLC) or Board of Directors (JSC). * **Signing Authority:** Board resolution authorizing signatory, or notarized power of attorney (Giấy ủy quyền công chứng). Legal representative named on ERC has inherent authority; additional signatories need explicit authorization. * **Address:** Conduit universal policy: lease (no time bound) OR utility bill OR bank statement, with utility/bank dated within 90 days. Same evidence satisfies both registered-address and operating-address checks. * **Good Standing:** Vietnam does not issue a separate Certificate of Good Standing; a dated ERC printout or real-time lookup at dangkykinhdoanh.gov.vn confirming active registration status serves as the live-status equivalent (subsumed-by-portal pattern). ## Person roles When you submit a person on the application body, set their `role` to one of Conduit's canonical `BusinessPersonRole` values. Use this table to map a local corporate-governance title onto the right canonical role. | Local role | Canonical API role | Description | | --------------------------------------------------------------------------- | ---------------------- | ------------------------------------------------------------------------------------------------------- | | Chủ tịch Hội đồng quản trị (Board of Directors Chairman — JSC) | `CONTROLLING_PERSON` | Chair of JSC Board of Directors; governance role. | | Thành viên Hội đồng quản trị (Board of Directors Member — JSC) | `CONTROLLING_PERSON` | Non-executive member of JSC Board; governance oversight. | | Chủ tịch Hội đồng thành viên (Members' Council Chairman — multi-member LLC) | `CONTROLLING_PERSON` | Chair of Members' Council; governance role in LLC. | | Thành viên Hội đồng thành viên (Members' Council Member — LLC) | `CONTROLLING_PERSON` | Member of LLC governing council; governance role. | | Tổng Giám đốc / Giám đốc (General Director / Director) | `CONTROLLING_PERSON` | Day-to-day operational executive; appointed by Board or Members' Council. | | Người đại diện theo pháp luật (Legal Representative) | `LEGAL_REPRESENTATIVE` | Person(s) named on ERC authorized to legally bind the company; must be Vietnam-resident (at least one). | ## Additional fields Country-specific fields you'll need to collect during onboarding, beyond the document uploads. | Field | Applies to | Reason | | ---------------------------------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------ | | `Nationality + Vietnam residency status` | shareholder | Enterprise Law 2020 and Investment Law 2020 impose foreign ownership caps in certain sectors; DPI tracks nationality to enforce FIE rules. | ## Notes * Enterprise Code = Tax Code since 2010: The 10-digit MST on the ERC is the same identifier used by GDT; do not request a separate tax registration certificate — the ERC itself suffices as dual proof unless a standalone GDT certificate is needed for banking purposes. * FIE dual-document requirement: Foreign-invested enterprises must produce both the IRC (issued under Investment Law 2020, Law No. 61/2020/QH14) and the ERC; neither alone establishes full legal status. As of 2026, ERC-first sequencing is permitted before IRC, but both must eventually be obtained. * Apostille Convention transition: Vietnam acceded to the 1961 Hague Apostille Convention on 31 December 2025; convention enters into force for Vietnam on 11 September 2026. Until that date, consular legalisation (notarisation + Vietnamese embassy/consulate stamp) remains required for foreign documents. From 11-IX-2026, apostille replaces the consular legalisation chain.
