Get a real Vietnamese virtual phone number — Hanoi 024, Ho Chi Minh City 028, Da Nang 0236, plus toll-free 1800. Vietnam's MIC regulator requires KYC. From $4.00/month, activation in 3-7 business days.
What is a Vietnam virtual phone number?
A Vietnamese virtual phone number is a real Vietnam DID delivered over SIP. Vietnamese numbering uses 3-4 digit area codes (with trunk prefix 0) — Hanoi 024, Ho Chi Minh City 028, Da Nang 0236, Hai Phong 0225. Internationally these are dialed as +84 followed by the area code without the leading 0. Vietnam is regulated by the Ministry of Information and Communications (MIC).
MIC requires KYC for Vietnamese number allocations — Vietnamese business registration for companies, or proof of identity plus a Vietnamese address for individuals. DIDHub manages the paperwork. Activation typically takes 3-7 business days. Vietnam is a fast-growing ASEAN market with strong manufacturing and tech sectors.
Common reasons businesses get a Vietnam virtual phone number:
- Vietnam market entry — Hanoi 024 and HCMC 028 numbers signal credibility to Vietnamese enterprise buyers.
- Manufacturing presence — Vietnam is a major manufacturing hub; local DIDs are essential for supply-chain operations.
- ASEAN regional — pair Vietnam with Thailand, Malaysia, Singapore, Indonesia, and Philippines DIDs.
- Tourism and hospitality — Da Nang 0236 for resort/travel-industry presence.
- Toll-free 1800 — free for Vietnamese callers, standard for customer service.
