hello guys can we use the same adsense code with same Publisher id on 2 different sites registered in 2 different countries...like one site Registered in india and second one registered in canada ...can they both use the same adsense code without being banned ?
This has been mentioned quite a number of times previously. Once the account has been approved, the same one can be used on multiple sites as long as the page is not against the program policies.
If your other sites adhere to adsense terms like the one which you got approved you can implement the code as many sites as you want.
