610.6 (C) Titles Consisting of Roman Letters and Arabic Numerals
The U.S. Copyright Office’s electronic registration system only accepts titles consisting of Roman letters and/or Arabic numerals. It does not accept titles consisting of other types of letters, numerals, or characters, such as Cyrillic or Mandarin. Nor does it accept diacritical marks used in Spanish, French, German, or other foreign languages, such as √ɧ, √ɬ†, √ɬ±, or √ɬº.
The system will accept titles written in a foreign language, provided that the title consists of Roman letters and/or Arabic numerals. The title will appear on both the certificate of registration and the online public record, but without any diacritical marks.
The Office will accept a title consisting solely of numbers and/or letters, such as
“L-1011,” “24601,” or “MX.”
