Information Leakage
The last digits of an EGN can reveal with reasonable accuracy the birthplace of a Bulgarian citizen, because of the long-lasting practice of assigning numbered sheets of paper to municipal ESGRAON divisions. Other divisions directly add the birth sequence number to the last 3 digits of their EKNM (a regional identifier) and possibly another 1 depending on the baby's sex. This practice is denied by ESGRAON officers, but is nevertheless used by civil authorities as a rule of thumb for checking the validity of an identity document.

Famous quotes containing the word information:
“So while it is true that children are exposed to more information and a greater variety of experiences than were children of the past, it does not follow that they automatically become more sophisticated. We always know much more than we understand, and with the torrent of information to which young people are exposed, the gap between knowing and understanding, between experience and learning, has become even greater than it was in the past.”
—David Elkind (20th century)
