To copyright a pen name — more precisely, to copyright a work you publish under a pen name — file an electronic application with the U.S. Copyright Office at copyright.gov, check the “Pseudonymous” box in the Author section, and enter your pen name. The standard filing fee is $65, or $45 if you are a single author registering one work you solely own. The decision that actually matters is whether to also list your legal name on the record, because it changes both your privacy and how long the copyright lasts.
You Are Not Copyrighting the Name Itself
Copyright protects original creative works fixed in a tangible form, such as a manuscript, a recording, or a finished painting. It does not protect names, titles, or short phrases. Federal regulation 37 C.F.R. § 202.1 specifically lists names and short phrases as material that cannot be copyrighted.1eCFR. 37 CFR 202.1 – Material Not Subject to Copyright So the pen name itself is not what you register — you register the work you created under it. If you want legal rights in the pen name as a brand, that is trademark law, handled separately by the U.S. Patent and Trademark Office.
How the Pseudonymous Checkbox Works
The Copyright Office’s electronic registration system (eCO) includes a checkbox labeled “Pseudonymous” in the Author section. You check it when the author is identified on the copies of the work only by a fictitious name, not their real one.2U.S. Copyright Office. Standard Application Help: Author You then enter your pen name in the Pseudonym field.
From there you have two choices for the legal name field. Leave it blank and only your pen name appears on the public copyright record. Fill it in and both names appear, creating a clear link between you and the work.
The Copyright Office encourages authors to provide their real name because it creates an unambiguous record of ownership and affects the copyright term, but there is no legal requirement to do so.3U.S. Copyright Office. Circular 32 – Pseudonyms Only check the Pseudonymous box if the pseudonym, not your real name, actually appears on the copies of the work, including any copyright notice.
How the Choice Affects How Long Your Copyright Lasts
If your legal name is on the registration, the copyright lasts for your life plus 70 years. If the registration stays fully pseudonymous with no legal name on record, protection runs for 95 years from publication or 120 years from creation, whichever expires first.4Office of the Law Revision Counsel. 17 USC 302 – Duration of Copyright: Works Created on or After January 1, 1978
For most individual authors, life plus 70 years is the longer term. Publish a book at 35, live to 80, and life-plus-70 gives you roughly 115 years of protection. The 95-year-from-publication term would be shorter. The 120-year-from-creation term only wins if you die young or the work sits unpublished for decades. In practice, listing your legal name almost always extends protection.
This is not permanent either way. You can reveal your identity later through a supplementary registration and switch to the life-plus-70 term, as long as you do so before the pseudonymous term expires.
Keeping the Whole Application Private
The Pseudonymous box only handles the Author field. Several other fields on the application also ask for a name, and everything you enter becomes part of the public record available online.5U.S. Copyright Office. Registering a Work (FAQ) If privacy is the goal, be deliberate about every field.
The Copyright Office allows you to use your pseudonym in the Claimant, Rights and Permissions, Correspondent, and Certification fields if you don’t want your real name appearing anywhere on the record.3U.S. Copyright Office. Circular 32 – Pseudonyms Authors who enter a pen name for the Author field but then type their legal name into the Claimant or Correspondent field defeat the purpose. Check every field before submitting.
Some authors go further and transfer ownership to an LLC or similar entity. If the entity is the claimant, only the business name shows on the record. That means separate state-level filings and fees, so weigh whether the added privacy is worth the paperwork.
Filing Steps and Fees
Filing happens online through the Copyright Office’s Registration Portal at copyright.gov.6U.S. Copyright Office. Register Your Work: Registration Portal The typical sequence:
- Create an eCO account and log in.
- Start a new claim and select “Standard Application” for most works. Enter the title and publication status.
- In the Author section, check “Pseudonymous,” enter your pen name, and decide whether to add your legal name. Even if you omit your real name, the application requires your nationality or domicile for pseudonymous works.7Office of the Law Revision Counsel. 17 USC 409 – Application for Copyright Registration
- Complete the Claimant, Rights and Permissions, and Correspondent sections using either your legal name or your pseudonym, depending on your privacy preference.
- Upload a complete digital copy of your work. Text works can go up as PDF or Word (.doc,.docx), audio as MP3 or WAV, video as MOV or MP4. Each file can be up to 500 MB.8U.S. Copyright Office. eCO Acceptable File Types
- Pay the non-refundable filing fee: $45 if you are a single author registering one work you solely own that isn’t a work made for hire, $65 for other electronic filings.9U.S. Copyright Office. Fees
- Electronically certify that the information is correct and submit.
You will receive an email confirmation on submission. The official certificate arrives by mail after the Office processes and approves the claim.
How Long Registration Takes
Based on Copyright Office data from April through September 2025, electronic claims that didn’t require follow-up correspondence averaged about 1.9 months. Claims with questions from the Office averaged 3.7 months. Paper filings ran significantly longer, at 4.2 months without correspondence and 6.7 months with it.10U.S. Copyright Office. Registration Processing Times
Your protection technically begins the day the Copyright Office receives a complete application, correct fee, and acceptable deposit copy. So while you wait for the certificate, your effective registration date is the day you submitted everything properly.
If Your Work Is Published in Print
If your work has been published in physical form, the Library of Congress may require you to deposit the “best edition” — the highest-quality physical version available. For printed books, that generally means hardcover over paperback and archival paper over standard paper.11Legal Information Institute. 37 CFR Appendix B to Part 202 – Best Edition of Published Copyrighted Works for the Collections of the Library of Congress Works published only online have separate digital requirements and don’t trigger a physical deposit. Ebook-only self-publishers won’t hit this rule.
Adding Your Legal Name Later
If you register under only your pen name and later want your legal name on the record, you can file a supplementary registration. It’s a separate application that adds your real name to the existing record without canceling or replacing the original.3U.S. Copyright Office. Circular 32 – Pseudonyms
Once your legal name is in the Copyright Office’s records, the term automatically shifts from the 95/120-year pseudonymous term to life-plus-70, assuming that term is longer. Supplementary registration costs $100 electronically or $150 on paper.9U.S. Copyright Office. Fees Before filing, you’ll need to review a copy of your original registration certificate, since the application requires you to certify that you have.
This is a one-way door. You cannot add your name and then remove it later. It works as a safety valve for authors who want privacy at launch and the option to claim credit later.
What Your Pen Name Does (and Doesn’t) Do If You Have to Sue
Registration matters beyond the certificate. Under federal law, you generally cannot file a copyright infringement lawsuit until you’ve registered the work or had your registration application refused.12Office of the Law Revision Counsel. 17 USC 411 – Registration and Civil Infringement Actions That applies whether you registered under your real name or a pseudonym.
The complication for pseudonymous authors is that filing suit in federal court typically requires identifying yourself. If someone infringes your work and you sue, you may need to reveal your legal name during litigation, even if it never appeared on the registration. Courts have limited mechanisms for allowing parties to proceed under pseudonyms, and whether a judge will permit it depends on the circumstances. Worth understanding before assuming a pen name buys absolute anonymity in an enforcement scenario.
For publishing contracts, the standard approach is to sign with your legal name followed by “writing as [pen name].” Your publisher or agent will need to know your real identity even if readers never will.
