DSAR Identity Verification: Confirm the Requester Before You Disclose Anything
Disclosing personal data to the wrong person is its own breach. Obtainer puts DSAR identity verification at the front of the workflow, so you confirm the requester before any data is gathered or disclosed, and only the right person receives the response.

Helps you comply, not legal advice
In short
DSAR identity verification is the step of confirming that a data subject access request really comes from the person whose data it concerns, before you gather or disclose anything. It matters because releasing personal data to an impostor is itself a data breach, so verification protects both the requester and the organization. Obtainer places identity verification at the start of the DSAR workflow: a request is not moved into discovery until the requester is confirmed, so data is only gathered for a verified person and the response goes only to the right one. Verification status is tracked on every request, and nothing is disclosed automatically, so you stay in control of what is disclosed. Obtainer helps you comply. It is not legal advice, and deciding whether a given proof of identity is sufficient stays with your team. It is self-serve DSAR fulfillment from $49/mo, not a six-figure governance suite.

What you get
Identity verification, built for privacy, legal, and ops teams
Verify before you gather
A request moves into discovery only once the requester is confirmed, so data is never collected for an unverified person.
Right person, right response
Confirming identity up front means the disclosure goes to the actual data subject, not an impostor.
Status you can track
Verification state shows on every request, so your team always knows which are cleared to proceed.
Your team sets the bar
Obtainer records the verification step, but whether the proof is sufficient stays your team's judgment, because it is not legal advice.
How it works
From an intake request to a ready-to-review response in four steps
Receive the request
Log the incoming DSAR and mark it as awaiting identity verification before anything else happens.
Confirm the requester
Your team checks the requester's identity to the standard it sets, and records the result.
Release it into discovery
Only a verified request moves forward, so data is gathered only for the right person.
Disclose to the right person
The approved response goes to the confirmed requester. Obtainer helps you comply. It is not legal advice.
Frequently asked
Questions teams ask about identity verification
Do you have to verify the identity of a DSAR requester?
Yes. Both the GDPR and the CCPA expect you to be reasonably sure the person asking is who they claim before you disclose or delete anything, because handing personal data to an impostor is itself a breach. Verify identity to a level that matches the sensitivity of the data, and do it before you gather records, not after.
How do you verify a data subject access request?
Match the request to information you already hold, ask for details only the real person would know, or use an account login where one exists. Avoid collecting new sensitive documents just to verify, since that creates more data to protect. The standard is reasonable confidence proportionate to the risk, not certainty.
Does verifying the requester pause the DSAR deadline?
Under the GDPR the one-month clock starts when the request arrives, and time spent verifying comes out of it, so verify quickly. The CCPA is more forgiving: its 45-day response period runs from receipt, but the regulations acknowledge verification time. In both cases, treat verification as the first urgent step, not a way to stop the clock.
What if you cannot verify the requester?
If you cannot verify identity to a reasonable level and the requester will not provide what you reasonably need, you can decline to act on the request, but you must tell the person, explain why, and note their right to complain. Document the attempt. Refusing to disclose to an unverified requester is a defensible position when it is recorded, not assumed.
Run a data subject access request end to end
Obtainer finds where a person's data lives across your systems, compiles it into one manifest, drafts the deadline-safe response, and tracks the GDPR and CCPA clock. You review, redact, and approve what gets disclosed. Helps you comply; not legal advice.
