Every document receives its own proof
After signing, BuiltSign automatically generates a unique certificate that is embedded in the PDF. Always verifiable, always transparent.
What is on the certificate page?
By default, BuiltSign adds a certificate page to every signed PDF: the certificate of completion. It shows the key details of the signing and a link to verify the document. The full audit trail, with the timeline, IP addresses and hashes, is in the separate audit certificate that the sender downloads from their account.
- Certificate ID
- A unique code per document. Use it to verify the document at builtsign.com/verify.
- Document
- The name of the document and when it was completed.
- Sender
- Name and email address of whoever sent the document for signing.
- Signers
- Name, email address and signature of each signer, with the time they signed.
- QR code and link
- Scan the code or open the link to verify the document online.
The audit trail
Every action on a document is recorded in an immutable timeline. As the sender, you find that timeline in the audit certificate.
Document created
Timestamp of upload and creation of the transaction
Invitation sent
Email sent to each signer with a personal link
Document opened
Signer has opened the link and viewed the document
Identity verified
Identity verification completed (if enabled)
Signature placed
With the time of signing; on Business and up also the time of each filled field
Document completed
All signers have signed. Document is final.
Certificate generated
Unique certificate created and embedded in the final PDF
Advanced identity verification
When a sender enables ID verification, BuiltSign uses an advanced AI-powered verification system. The signer scans their government ID and takes a selfie. Our system automatically matches the two and determines a confidence score. The result, verified or not, is recorded in the audit trail. BuiltSign does not store a photo or scan of the ID document, nor the selfie. We do store the extracted name, and in encrypted form the date of birth and document number. The extended audit certificate shows details including the document number and date of birth.
Verify a signature
Anyone can verify a BuiltSign signature, no account needed.
Via builtsign.com/verify
Go to builtsign.com/verify, enter the certificate ID (found on the certificate page of the signed PDF) and instantly see a summary: the signers, the registered hashes and, if one was issued, the independent timestamp. Or drop the PDF in to check that it is unchanged.
Via the embedded certificate page
Open the signed PDF. The certificate page at the end shows the document name, the signers with their signature and signing time, the certificate ID and a QR code that links to the verification page.
