Digital PE Seals and Electronic Signatures: Submission Checklist
Prepare digitally sealed engineering documents without confusing an image of a stamp with a compliant electronic signature or board-approved process.

Key takeaways
- An image of a seal and a compliant digital signature are not necessarily the same thing.
- Board rules and permit-portal requirements must both be checked.
- Post-signing edits can invalidate a digital signature.
Three requirements may apply at once
A digital submission can be governed by the engineering licensing board, the authority having jurisdiction, and the permit portal's technical rules. The accepted signature method, file format, certificate behavior, and visible seal requirements may differ.
Confirm the rules before final delivery rather than converting or flattening files after the engineer signs them.
Digital submission checklist
- Confirm whether electronic or digital signatures are accepted
- Ask whether a third-party certificate is required
- Verify visible seal, signature, and date requirements
- Confirm whether one signed cover sheet or individually sealed sheets are required
- Do not merge, optimize, print-to-PDF, or edit signed files without approval
- Retain the original issued file for signature validation
Avoid common file-handling mistakes
Combining PDFs, running aggressive compression, changing pages, or printing a signed PDF to a new file can remove signature validation data. If the permit portal rejects file size or format, ask the engineer for a compliant export rather than altering the sealed deliverable.
Frequently asked questions
Is a scanned wet stamp the same as a digital seal?
Not necessarily. Terminology and acceptance rules vary. Confirm the required method with the licensing board and reviewing authority.
Why does a signature show as invalid after upload?
The file may have been modified, processed, or recombined after signing. Compare it with the original issued file and ask the signer or permit portal for guidance.
