it is the in the UK, and is missing numbers. im from england and call there all the time, but you wont be able to call that since he left off the country code. to call him you would have to add 011 in front...(01144...) otherwise it wont go through. id say cash the check and tell him he has to wait 3 days for it to clear? but i thought some checks can clear, then the money dissapears on them? id say tell him once you recieve the check theres a 7 day processing time.
