Vietnam MIC Sender Registration + Marketing Rules

Vietnam (VN) runs a sender-registration regime for A2P SMS under the Ministry of Information and Communications (MIC). The country-rules row carries the current channel-specific answer, including the required registration level and accepted sender types. This page documents tenant-owned controls. Devotel Orbit provides the country-rules reference, sender-registration tracking, consent ledger, suppression, and quiet-hours surfaces; your organization owns its legal posture, filings, and message content. This page is documentation, not legal advice.

The MIC and Vietnamese carriers can filter or reject unregistered or misleading sender identities and can take action on unsolicited traffic. Confirm current filing requirements with your carrier or counsel before launch. An approved Orbit registration is not regulator approval.

1. Accepted sender types and registration level

Start with the live VN row before choosing a sender:

curl "https://api.orbit.devotel.io/api/v1/compliance/country-rules?channel=sms&country=VN" \
  -H "Authorization: Bearer $ORBIT_API_KEY"

The current feed marks Vietnam’s registration level as required and supports alphanumeric sender identities. A sender registration is a precondition for an alphanumeric A2P SMS launch; do not infer that a sender will deliver simply because it passes local format validation. If the live row lists another sender type for your channel, follow that row and confirm operator support before sending.

VN posture	What you do
Alphanumeric sender	Submit a brand-aligned sender through Sender-ID Registration and wait for the VN entry to reach `approved`.
Registration	Treat `required` as a launch prerequisite. Keep campaign traffic in rehearsal until the registration is approved.
Brand identity	Use a sender that recipients can associate with your organization. Keep the business and authorization documents that support it in your KYC profile.
Other sender types	Check `sender_types` in the live row and the operator’s current rules before using a long code, short code, or another identity.

A tenant-owned send gate may hold traffic while the registration is pending. That is different from a carrier rejection. If a send is held, inspect the VN row and the registration status before changing the message.

2. Vietnamese stop-keyword family

Publish the opt-out instruction in the language your audience understands. For Vietnamese SMS, keep the standard English terms visible and support the common Vietnamese equivalents in the tenant’s opt-out rules:

Action	Suggested keywords
Stop messages	`STOP`, `UNSUBSCRIBE`, `CANCEL`, `DUNG`, `NGUNG`, `DUNG GUI`
Resume messages	`START`, `SUBSCRIBE`, `TIEP TUC`

Configure the exact terms used in the campaign’s consent text and footer in Opt-Out Keyword Alias Table. Match case and trailing punctuation according to the alias-table rules, and test a sample reply before launch. Treat an opt-out as a tenant suppression at scope all when the recipient is asking your organization to stop contacting them, not merely as a delivery preference for one campaign. If you use a different Vietnamese-language term, add it as a tenant-owned alias and document it in the campaign record. Do not assume that a free-form sentence is an exact keyword match; make the instruction and the matcher agree.

Capture express, purpose-specific consent before sending promotional SMS. Vietnam’s marketing-SMS regime is anchored in Decree 52/2013/ND-CP on the management of telecommunications information, with enforcement by the MIC and related agencies. Keep a record of:

the recipient identifier and the sms channel;
the purpose and consent text version shown at capture;
when and how the recipient gave consent; and
a proof reference that your team can retrieve.

Record the evidence in the Consent Management ledger. A registration-approved sender does not replace recipient consent, and consent does not replace the sender-registration requirement.

curl -X POST https://api.orbit.devotel.io/api/v1/compliance/consent \
  -H "Authorization: Bearer $ORBIT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "identifier": "+84912345678",
    "channels": ["sms"],
    "opt_in": true,
    "lawful_basis": "consent",
    "purpose": "VN marketing SMS — promotional updates",
    "consent_text_version": "vn-marketing-v1",
    "consent_proof_url": "https://example.com/consent/evt_vn_123"
  }'

Set the tenant’s unknown-marketing policy deliberately. For a marketing program without a consent record, refuse is the safer tenant-owned posture; review the policy and its evidence in Consent Default Policy.

4. Quiet-hours convention

There is no single Orbit-enforced Vietnam SMS quiet-hours window. Set a recipient-local tenant window that your counsel and operator accept. A conservative starting convention is 22:00–07:00 Indochina Time (UTC+7) for marketing traffic, with emergency, transactional, or recipient-requested messages classified separately under your policy. This is a tenant choice, not a platform-wide VN block. Configure and preview it in Quiet-Hours Configuration and Quiet-Hours Preview. Keep the setting in the campaign record so the consent and send-time decisions are auditable.

5. KYC profile submission for a VN sender

Assemble the tenant-owned compliance profile before filing the sender. Follow the complete KYC Profile Submission Runbook:

Upload current business registration, address, identity, and authorization documents that support the sender and the entity submitting it. Keep the returned doc_… identifiers.
Create a profile for Vietnam with use_case: "sms_sender_id_alphanumeric" and the VN destination.
Attach the document IDs, including an authorization document when an agency submits for a brand, then submit the profile for review.
Wait for the profile to reach approved; a draft or pending profile is not carrier approval.
Submit the VN sender registration through Sender-ID Registration, reference the approved profile, and wait for the VN registration to report approved.
Recheck the live VN row, consent record, opt-out aliases, and quiet-hours preview before the first campaign send.

Renew documents before expiry. The runbook’s clone-and-replace sequence keeps an approved profile attached while its replacement is under review.

6. Worked configuration before the first VN send

Read the VN row

Call GET /compliance/country-rules?channel=sms&country=VN and record sender_types, registration, content_restrictions, and stop_requirement.

Choose and support the sender

Choose a brand-aligned alphanumeric sender supported by the live row and collect the documents that connect it to your organization.

Submit the KYC profile

Use the KYC Profile Submission Runbook and wait for the profile to reach approved.

File the VN sender registration, reference the profile, and wait for the VN entry to reach approved before production traffic.

Capture consent and publish opt-out terms

Confirm the recipient has an sms consent record and that the message exposes the English or Vietnamese stop terms configured in your alias table.

Set and preview quiet hours

Configure the tenant’s recipient-local window, starting with 22:00–07:00 Indochina Time for marketing, and verify the preview result.

Send a controlled test

Verify the sender, consent, suppression, and registration status, then send a small tenant-owned test before scaling the campaign.

This page is documentation, not legal advice. The MIC and Vietnamese mobile operators may change their requirements. Have counsel and your carrier review the sender filing, consent language, stop keywords, and sending hours before you launch.

Country Compliance Requirements — read the live VN row and its channel-specific fields.
Regional Posture Hub — the matrix of country pages and the check-the-row-first workflow.
Sender-ID Registration — submit and track the VN sender entry.
KYC Profile Submission Runbook — upload, assemble, submit, approve, and renew the profile.
Consent Management — capture and retrieve marketing consent evidence.
Opt-Out Keyword Alias Table — configure English and Vietnamese tenant aliases.
Quiet-Hours Configuration — set the tenant-owned recipient-local window.
Send Gates — understand the send-time surfaces.

The legal posture remains tenant-owned; confirm current MIC and operator requirements before each materially different campaign.
