How Police in Vietnam Request Data from WhatsApp, Instagram and Facebook
Authorised police and government officials in Vietnam can send preservation, emergency and records requests directly to Meta through its law-enforcement portals. For the content of messages, Meta says a mutual legal assistance treaty (MLAT) request or letter rogatory may be required. Vietnam has no bilateral mutual legal assistance treaty with the US in force, so where content is needed Meta's guidance points to a letter rogatory (a court's letter of request), sent through diplomatic channels.

How to make the request
- Preserve first. Send a preservation request so the account data is kept while legal process is prepared; Meta preserves records for 90 days pending formal process.
- Use the official portals with an official government email. Facebook and Instagram: Meta’s Law Enforcement Online Request System (facebook.com/records). WhatsApp: whatsapp.com/records. Step-by-step: our Facebook & Instagram and WhatsApp portal guides.
- Attach valid legal process under Vietnam’s law for records requests, and identify the account precisely (username, profile URL, phone number with country code).
- Emergencies: where there is imminent harm to a child or a risk of death or serious physical injury, use the portal’s emergency request route.
- Content: Vietnam has no bilateral mutual legal assistance treaty with the US in force, so where content is needed Meta's guidance points to a letter rogatory (a court's letter of request), sent through diplomatic channels. When to use which channel: MLAT vs LERS vs Interpol.
