Here I would like to add to Indian user that for INDIAN phone number this might not work correct for all phone number. for Indian phone number  because  database is all based on crowd-data that means if some one has sync his /her phone number with truecaller then it possible that your number can be searchable.so finally you can't relay fully on this search result.Suppose someone using this application and he has allowed to sync the phone book with database of True caller then all his phone book will get added to True caller database. Since in India there is no Public mobile phone directory so relevancy of the search number may not be always correct. Some time if someone has added some nick name or wrong name with his friend phone number in his mobile phone book then same it will be get added to true caller database after sync and it will be visible as nick name while searching.

It is supported everywhere in the world.
Truecaller caller id will only be activated on incoming or outgoing calls where the number isn't previously stored on your phonebook. (Some limitations like hidden numbers or smartphone platform restrictions apply)
