Product Introduction

009 International Direct Dialing (IDD) allows customers to directly dial international phone numbers using the prefix 009, without going through an operator via the 100 international switchboard. Currently, this service is available for 244 countries or regions and is commonly referred to as IDD.


Dialing Method

International Access Code (009/002) + Country Code + Area Code + International Phone Number
For example, to dial Tokyo(area code 03), Japan directly from Taiwan:

009 81 3 xxxxxxxx
Or
002 81 3 xxxxxxxx

To make an international call, first dial the international access code (009 or 002), followed by the recipient’s country code, area code, and phone number. Note: Do not dial the leading zero in the area code.


If you have any questions regarding the "International Direct Dialing" service, please call our customer service hotline at 0800-080123, and our representatives will be happy to assist you!

Note: 002 is a public international access code. Chunghwa Telecom customers can also use 002 to make international calls. However, 009 is Chunghwa Telecom’s exclusive international code. Using 009 may offer promotional rates from time to time (please refer to promotional announcements). We recommend using 009.
