The short answer: If someone has asked you to be their credible identifying witness, it means they need you to certify their identity during a notarization because they can't complete standard identity verification. This article explains what you need to have ready and what to expect during the process.
What You'll Need
- A government-issued photo ID (driver's license or passport).
- The last 4 digits of your U.S. Social Security number or individual tax identification number (ITIN). This must be tied to sufficient records to generate identity verification questions — such as credit history or vehicle registration.
- A device with a supported browser (Chrome, Firefox, or Safari), plus a working camera, microphone, and speakers.
1. Receive the First Email
Proof sends you an email with the signer's name, a request to act as their witness, and a list of items to have ready.
2. Watch for a Second Email
When the signer is in a meeting with the notary, you'll receive a second email with a link to join. Select the link to begin.
3. Verify Your Identity
Complete the two-step identity verification process: a knowledge-based authentication (KBA) quiz and credential analysis. You verify your own identity — not the signer's.
4. Join the Meeting
After passing verification, you join the meeting on your own device. The notary reviews your ID to confirm your identity.
5. Take the Oath
Take an oath or affirmation before the notary confirming that the signer is who they claim to be but lacks other standard forms of ID.
6. Leave the Meeting
Once the notary confirms your duties are complete, you may leave. You don't need to stay for the rest of the signing session.
Summary Checklist
- Have your photo ID and the last 4 digits of your SSN or ITIN ready before the signer starts their meeting.
- Watch for the second email from Proof — it arrives when the signer is in the meeting and ready for you to join.
- Complete KBA and credential analysis to verify your own identity, then join the meeting.
- Take the oath confirming you know the signer, then leave when the notary releases you.
