How can I identify a call made from overseas?
For easy identification, all calls made from overseas will have a "+" sign as a prefix.
Will calls made from local numbers also have the same display format?
No, local calls will not have a "+" prefix. Local numbers have 8 digits and will usually start with "6", "8" or "9". For example, 90123456.
How can I identify a possible scam call from overseas?
An overseas number being disguised as a local number will have a "+" prefix. For example, if the overseas caller is trying to use the local number 61005678, it will instead appear as +61005678.
