Calling Vietnam: what to know

Vietnam answers on the country code +84, with the capital in Hanoi and most business concentrated around Ho Chi Minh City, Hanoi and Da Nang. The working language for business is Vietnamese, and local offices generally keep hours of 8:00 to 17:30 with a long lunch 11:30 to 13:30. Many offices observe a nap break.

Outbound calls on Intercalling need no phone number and no app. You place them from the browser, and you only add a US or Canada number when you also want to receive inbound calls.

Most mobiles in Vietnam sit on operators such as Viettel, Vinaphone (VNPT), MobiFone. Vietnam restructured all mobile prefixes in 2018 to 0120-series became 070-079, 0121 became 079, etc. Older databases may have outdated prefixes.

Vietnam runs on UTC plus 7, and it does not observe daylight saving, so the time difference stays constant through the year.
