Today had to find some Int dialing code. Got call from interesting no then had to find out which country it is.
I find 2 sites specially very useful and easy.
It has alphabetically organized country code for all country. Its very easy to use and very simple.
It has nice looking layout. Its gives extended service too like some time dialing codes differs on from which country we are dialing. This site is nice, it shows different time on calling country and from where its been called.
