Ways to dial

Various methods to call Vietnam

Several routes connect you to Vietnam (+84) landlines, calling cards and modern VoIP services. Pick the one that fits your call volume and budget.

01

Calling Vietnam from a landline or mobile

Dial your exit code (00 from most countries, or 011 from North America), enter +84, then the local Vietnam number — dropping any leading 0. Vietnam's 2-digit country code puts it in ITU Zone 8 of the global E.164 numbering plan.

See dialing steps→Classic
02

International calling cards for Vietnam

Vietnam uses a 2-digit country code (Zone 8). Check that the card lists +84 rates explicitly — mobile numbers in Vietnam often carry a different per-minute charge than landlines. Factor in the Asia/Ho_Chi_Minh time zone when planning the call.

See dialing steps→Pre-paid
03

VoIP services for contacting Vietnam

Apps like Skype, WhatsApp and Viber, and business VoIP from TKOS are the cheapest route to Vietnam (+84) — calls to Vietnam (Asia/Ho_Chi_Minh) travel across trans-Pacific or Indian Ocean fibre — a solid broadband or 4G connection keeps latency below 180 ms.

Tips for clear & uninterrupted calls

Whether you're reaching Vietnam for business or family, three habits keep every conversation crystal clear and a clean route from TKOS handles the rest.

  • 01

    HD audio for Vietnam calls

    East Asian routes to Vietnam support G.722 wideband — an HD-compatible headset delivers noticeably clearer voice on these high-traffic transoceanic links.

  • 02

    Connection quality to Vietnam

    Trans-Pacific and Indian Ocean routes to Vietnam run 120–180ms round-trip — wired ethernet keeps packet loss below 0.1% where Wi-Fi adds jitter spikes on these longer paths.

  • 03

    Best time to call Hanoi

    Schedule Vietnam calls during Hanoi business hours — 09:00–17:00 Asia/Ho_Chi_Minh — your contact will be at their desk in a quiet space rather than taking the call on the move.

Decision guide

Choosing the right service for calling Vietnam

When selecting an international calling service for Vietnam, four factors separate the durable providers from the noise. Look for a proven track record on each.

Coverage

Trans-Pacific routes to Vietnam vary — verify direct Hanoi interconnects, not East Asian hub routing.

Reliability

Trans-Pacific fibre cuts happen — require redundant cable paths and a sub-1-hour failover SLA for Vietnam.

Customer support

Confirm coverage for Asia/Ho_Chi_Minh hours — a Hanoi route issue at 09:00 needs a human response, not a next-day ticket.

Transparent pricing

East Asian rates vary per city — request a full rate deck for Hanoi and every city you'll dial.

FAQ

Questions about calling Vietnam, answered.

Everything a business or traveller needs to know before dialling Vietnam (+84). Can't find an answer? Our team is one click away.

Q1.What is the country code for Vietnam?
Vietnam's international calling code is +84. Dial it immediately after your exit prefix and before the local subscriber number whenever calling from outside Vietnam.
Q2.What is the + sign for when dialling Vietnam?
The + replaces your local international exit code. When you call Vietnam using +84, your carrier automatically substitutes the correct exit prefix (00 in Europe, 011 in North America, 0011 in Australia) before the call goes out.
Q3.What time zone does Vietnam use?
Vietnam uses the Asia/Ho_Chi_Minh time zone. Factor in the Hanoi local time before placing calls — the best window for business calls is typically 09:00–17:00 Asia/Ho_Chi_Minh.
Q4.How do I call Vietnam from abroad?
Dial your international access prefix (press + on mobile, or dial 00 / 011 from a landline), enter 84, then the local Vietnam number — dropping any leading 0 from the area or mobile code.
Q5.Why won't my call to Vietnam connect?
Common causes include dialling the wrong exit code, keeping the leading 0, or missing digits in the subscriber number. Double-check the format: + 84 [area code without 0] [local number]. Also confirm your plan includes international dialling to Vietnam.
