In mobile telecommunications network routing, '''E.214''' is one of three prevailing [[numbering plan]]s used for delivering [[mobility management]] related messages.<ref>{{Cite web|url=https://www.itu.int/rec/T-REC-E.214|title=E.214 : Structure of the land mobile global title for the signalling connection control part (SCCP)|last=|first=|date=|website=www.itu.int|url-status=live|archive-url=https://web.archive.org/web/20191114054203/https://www.itu.int/rec/T-REC-E.214|archive-date=2019-11-14|access-date=2019-07-18}}</ref>

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.<ref>{{Cite book|url=https://books.google.com/books?id=b5d0_au-z9MC&pg=PA219|title=3G Networks|last=Kasera|first=Sumit|last2=Narang|first2=Nishit|date=2004|publisher=Tata McGraw-Hill Education|year=|isbn=9780070527997|location=|pages=219|language=en}}</ref>  

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|global title translation]], is the [[Signaling System 7|SS7]] equivalent to [[Internet Protocol|IP]] routing.  E.214 numbers are routed separately from [[E.164]] numbers since they are marked with a different [[Numbering Plan Indicator]].  However, it is possible to reuse the [[Global Title]] analysis tables used [[E.164]] numbers everywhere except for the final destination network of the message.  This saves considerable administrative work.
