Registered child sex offenders in the United States of America will now have new passports indicating their previous crimes.

The State Department said Wednesday it would begin revoking passports of registered child sex offenders and will require them to apply for a new one that carries a “unique identifier” of their status.

Those applying for a passport for the first time will not be issued one without the identifier, which will be a notice printed inside the back cover of the passport book that reads: “The bearer was convicted of a sex offense against a minor, and is a covered sex offender pursuant to (U.S. law).”

The State Department, which issues U.S. passports, said it will start notifying those affected as soon as it receives their names from U.S. Immigration and Customs Enforcement at the Department of Homeland Security.

That agency is charged with identifying child sex offenders and is the sole agency that can add or remove someone from the list.

State Department officials said they weren’t aware of any other group of felons who’ll be identified as offenders in their passports.
