The
E.164 numbering plan, which is a maximum of 15 digits and usually written with a "+" prefix, is the historic first-generation format representing the phone number. The E.212 is a second-generation number plan used in America, extended to include the subscriber's MSIN (Mobile Subscription Identification Number) within the network's customer base. The E.214, developed under European

In routing a transatlantic mobile call, numbers routed from European networks are converted from E.214 numbers into E.212 numbers at the boundary incoming toward America (this can mean the
Signaling Transfer Point at the edge of the American operator's network). In the outgoing direction, from America toward the rest of the world, numbers are converted from the E.212 standard to the E.214 standard.
This process, called
global title translation, is the
SS7 equivalent to
IP routing. E.214 numbers are routed separately from
E.164 numbers since they are marked with a different

E.164 numbers everywhere except for the final destination network of the message. This saves considerable administrative work.
