Uploading Your Work to eCO

The January 2015 eCO update includes a new streamlined process for uploading copies of your work to eCO. After confirmation of fee payment, you can select files from your computer, upload them, and confirm completeness all on a single screen.

In addition, the maximum size for each file uploaded has been increased from 170 MB to 500 MB.

Tip: If you are uploading a large number of files for a single application, we recommend that you first compress the files by zipping them, then select and upload the zipped files. The compressed files will be received more quickly by the Copyright Office than files uploaded individually.
