The passports of Americans convicted of sex offenses against a child will soon bear a mark of their crimes.

The State Department announced this week that a sentence noting their conviction would be added to the back inside cover of offenders’ passports.

Once the State Department receives their names from the Department of Homeland Security, it will begin notifying affected sex offenders that their passports were being revoked and reissued with the new language.

Smaller passport cards, which can be used only for very limited international travel, will not be issued to such offenders because they lack room for a similar message. It was not immediately clear how many passport holders would be affected.
