i may sell an item to someone in norway, to receive payment they want my bank account number and sort code number to transfer the money, is this safe to do?
I agree with both cheekychops and sqad.
If you are nervous of this, though, you could set up a Paypal account for them to transfer money into.

In your case though providing this is not a response to an unsolicited transaction and providing you're not a celebrity with details of things like your date of birth readilly available on line you should be OK
