## Frequently asked questions

What is the area code for Hanoi?

The area code for Hanoi, Vietnam is 24. Calling from outside Vietnam, dial your exit code, then +84, then the area code without its trunk prefix, then the local number — written together as +84 24 followed by the subscriber number.

How do I call Hanoi from abroad?

From the United States or Canada, dial 011 + 84 + 24 + the local number. From most of Europe and from a mobile anywhere, replace the exit code with 00 or simply press and hold 0 to enter a plus sign, which works from any country without knowing its exit code.

Do I drop the 0 when calling Hanoi?

Yes. Vietnam uses 0 as a trunk prefix for domestic calls, so Hanoi's code is written 24 locally and dialled as 24 from abroad. Keeping the trunk prefix in an international number is the single most common reason the call fails to connect.

How many digits is a Hanoi phone number?

A full Vietnam number is 10 digits after the country code, area code included — for example +84 24 1234 5678. That length is fixed by the national numbering plan, so a number one digit short is a typo rather than a valid shorter number.

How much does it cost to call Hanoi?

Calling a Hanoi landline costs $0.65 a minute with Telvio and a mobile costs $0.65. Ten minutes to a landline is $6.50. Billing is per second with no connection fee, so a short call is charged for the seconds it used rather than rounded up to a whole minute.

## Call Hanoi with Telvio

From $0.65/min. Per-second billing, 1 free minute included.
