Electronically Submit Critical Infrastructure Information (CII) for PCII Protection

In the center of the graphic is the PCII logo, a sphere composed of images of various critical infrastructure sectors surrounded by a weave of green lines that form protective barrier around the critical infrastructure. Five laptop computers with a picture of all the continents on their screens surround the PCII logo. Pieces of paper are flying from the computers to the PCII logo.Submitters should consider contacting the Protected Critical Infrastructure Information (PCII) Program at PCII-Assist@hq.dhs.gov prior to submitting their information to ensure that the Program can accept the submission format and for answers to any additional questions.

The PCII Program or Designee will acknowledge receipt of the submission within 30 days of its receipt. Acknowledgement of receipt is not a determination of validation, only a notification to the submitter that the PCII Program or Designee has received the information accompanied by an Express Statement. The submission will be protected as PCII during the validation period. Once the submission is validated, the submitter will receive a validation letter or an email that will include a submission identification number. Submissions that do not meet requirements are destroyed or returned to the submitter, as determined by the submitter's written preference.

Submission Guidelines

These guidelines will help you successfully complete an electronic submission via the eSubmission platform:

  • The electronic submission process MUST be completed in a single session as information cannot be saved and completed at a later date.
  • All necessary information should be available prior to beginning the electronic submission process as the session will end and all information will be deleted after 20 minutes of inactivity. Submitters will be prompted before they are disconnected to give them an opportunity to continue with their submission.
  • The time required to submit information will depend on the number, size, and format of the uploaded files as well as the connection speed.
  • There is no limit on the number of times an individual can submit information, but each submission cannot exceed 100 files or be greater than 1 GB in total size.
  • Submitters must use Microsoft Internet Explorer version 9 or higher, Firefox, or Google Chrome as their browser.
  • All file types and formats are accepted by the PCII Program.
  • As a further security measure, submitters are encouraged to provide a digital signature. Although not required, a digital signature authenticates the submitter's identity, guaranteeing the original content of documents has not been altered in transmission. A Certificate Authority issues digital signatures and can be located through most online search engines.
  • Identify the primary contact in case the PCII Program Office has questions about a submission. Provide the contact's name, organization name, mailing address, city, state, zip code, email address, and telephone number. A secondary point of contact may also be designated.
  • Indicate the tracking number provided in the confirmation letter if the current submission is supplying additional information to support a prior submission.
  • Verify that the information listed in the Certification Statement:
    • Is not customarily in the public domain.
    • Has the submitter's most updated contact information.
  • If the information submitted is required by the federal government, specify the department or agency and identify the legal authority that mandates the submission.
  • Provide a brief description of the information in each file to be submitted before attaching and uploading files.
  • Selecting the "Cancel" button before uploading files will end the submission process, and all information related to the submission will be deleted.
  • The submission process cannot be cancelled after files have been uploaded to the PCII Program.
