The majority of free sites have been created in such a way that they accommodate US citizens.
There are sites that do accommodate other countries but they are a few. Like if you wanted to find someone free (Canada) are there any tools that are suited for this type of search? The answer to that is an obvious yes, and I will mention some of those ways in the following paragraphs
A number of countries comprise of local headquarters of large search engines like Google and Yahoo. I will concentrate on Yahoo since it is the only search engine that puts forward a free people service. Besides the USA, countries like the UK, Canada, Australia and Ireland are some of the countries that you can find Yahoo. Yahoo has a people search service that you can use to find someone for free (Canada).
There are a number of searches that can be done using yahoo people Canada. The directory will give you permission to do a reverse email search, browse with a name only, you can perform a reverse address search and a reverse phone number search. Since this is a Canadian directory, the searches that you perform from here will put its mind only on Canadians.
The phone book is also an appropriate place to search for pelple.
There are very few countries that do not have a copy of their own white pages and you can also use the Canadian whitepages to find someone for free (Canada). Besides the email address search, you will be able to execute the same kinds of searches in Yahoo.
The way people can be found can be sizeable by the info in the phone directory. In my opinion these two places provide the best chance for you to find someone for free (Canada).
