In mobile telecommunications network routing, E.214 is one of three prevailing

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 GSM (Global System for Mobile Communications) standards, is a comparable extended second-generation format used outside America and can be more or less than 15 digits.^[2]

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

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

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