U.S./North American area code +1 447 will go into service in 2014
as an ordinary geographic area code, as an overlay on area code +1
217 for part of Illinois including Champaign and
Mexico also has an area code 447, serving northeastern Michoacán,
including Maravatío. Landline numbers are +52 447; mobile phone
numbers are +52 1 447. The remainder of the number is a further 7
digits for landlines and mobiles.
Other countries may have a domestic area code 447 or similar.
However, "area code 447" often refers to a range
of numbers in the United Kingdom (telephone country code +44).
Numbers beginning with +44 7400 through +44 7999 are mobile phones,
but numbers beginning with +44 70 are personal "follow-me" numbers
that can be forwarded to anywhere in the world. Some of these
"follow-me" numbers may be legitimate, but they are also very
popular with Internet scammers.
Scam phone numbers in the United Kingdom (+44):
Most "419" scams using +44 70xx numbers involve emails that are
sent from Nigeria and other West African countries, not from the
UK! If you see a +44 70xx number in a 419 scam email it usually
means you're dealing with criminals based in Nigeria.
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 UK£ 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.
In most cases when you call one of these numbers the phone that
starts ringing will actually be a mobile phone somewhere in
Nigeria, as the UK number has been programmed to auto-forward calls
to another number. These +44 70xx numbers are used as a redirect
service to obscure the fact that the person taking the call is not
actually based in Europe. The UK number is used to lend credibility
to the scam.
