After long long and long interval I am again infront of you with a valuable information, which I have got from my friend of cyber crime investigation field, who gave me the link of "joewein.de", and I am bringing this in front of you as this will help you a lot for identifying the 419 spammers. So here is the details of that information as published by that website.
Scam phone numbers in the United Kingdom (+44):
If an email mentions a UK phone number starting with +4470, it usually means that the sender of that mail is not in the UK at all and it is almost guaranteed to be a scam.
Usually the presence of a +44 70 number in a 419 scam email means you're dealing with criminals based in Nigeria who are using these numbers to make people believe they're dealing with someone legitimate who is in the UK instead of a criminal in an Internet cafe on a different continent.
Do not reply to any emails that mention +4470 phone numbers!
Never call such numbers!
Break off all contact with these people!
The scammer most likely is NOT based in the UK. +44 70 numbers belong to international call forwarding services. Their whole point is that people can reach the user of the number when he's not in the UK. These services make it possible for scammers to hide the fact that they are based in Nigeria or other countries in Africa, while the scam victim will believe they're dealing with someone in the UK. Very few (if any) legitimate individuals use these numbers. Banks, law offices, UK immigration officials, etc. never use +44 70 numbers because, since their offices are based in the UK, they have no need to redirect calls to their offices to sohttp://www.blogger.com/img/blank.gifme mobile phone outside the UK. We have not come across any legitimate UK businesses yet that use +44 70 numbers. Their only visible user base are scammers in Nigeria, South Africa and elsewhere. It is a perfect mystery to us why the UK authorities allow these services to continue operating despite them being used almost exclusively by criminals.
UK phone numbers starting with '70' are "Personal numbering" in the "Find me anywhere" range. Charges for calls to these numbers are not distance-dependent. They can cost as much as UKL 0.50 (USD 0.90) per minute to call and can forward the call to virtually any phone number in the world. Forwarding numbers can be set up for free and completely anonymously via websites such as uknumbers.com.
