Having trouble contacting us?
Global Affairs Canada has changed from its 30-year-old phone system to a new Voice over IP (VoIP)* or IP Telephone system. As a result, we now are using the new National Capital Region (NCR) area code “343”. All new Global Affairs Canada phone numbers in the NCR are now 343 with the new “203” prefix.
There may be cases where private telephone systems across Canada have not yet been programmed to recognize this new “343” area code and “203” prefix. If you have problems phoning us, please contact your local phone line provider and ask them to ensure that your phone system allows you to call 343-203 numbers. You may provide them with the phone number of +1-343-203-0100 as a test line; this is our voice mail line and it will be answered 24/7.
