How WhatsApp is used in Vietnam
Vietnam is inexpensive across the board, but WhatsApp competes with Zalo, which dominates domestic messaging. That makes WhatsApp most useful for cross-border sellers and for audiences with international ties rather than as a mass domestic channel. Where it does reach, the low rates make rich transactional flows easy to justify.

Meta bills every country in “Rest of Asia Pacific” at the same rate, so these markets cost exactly the same to message as Vietnam: Afghanistan, Australia, Bangladesh, Cambodia, China, Japan, Laos, Mongolia, Nepal, New Zealand, Papua New Guinea, Philippines, Sri Lanka, Taiwan , and others.

Frequently asked questions
Should I use WhatsApp or Zalo for Vietnamese customers?
For a purely domestic audience, Zalo has far greater reach. WhatsApp earns its place for cross-border commerce, expatriate customers and businesses that already run a single WhatsApp stack across several markets.
Does my own country matter, or only Vietnam?
Only your customer's. Billing follows the recipient's country code, so a business anywhere pays the Vietnam rate to message a Vietnam number.
What is free when messaging Vietnam?
Replies inside the 24-hour customer service window cost nothing. The window opens whenever a customer messages you and resets on every new message from them, so a support-led setup can run at a fraction of a campaign-led one.
Why is there no separate Vietnam rate?
Meta prices about thirty markets individually and groups the rest into regions. Vietnam sits in “Rest of Asia Pacific”, so that regional rate is the actual price you are charged — there is no separate Vietnam line on the rate card.
