What consent evidence should come with a purchased lead?
Eight elements worth checking when buying leads, why they matter and the questions to ask your suppliers.
Check the evidence before you call.
When you buy a lead, a consent flag doesn’t tell you the whole story.
AdPriva is designed to give lead buyers access to the consent wording displayed, the action recorded, and an assessment of whether the submission came from a human or automation. All linked through one Evidence ID, with a signed record buyers can check.

- Record integritySigned evidence, checkable for changes
Why it matters
The lead may change hands. The responsibility doesn’t disappear.
Since 11 August 2026, most commercial prospecting calls to consumers in France require prior consent. The business making the call must be able to demonstrate that consent was obtained.
What the lead file says
- Name
- contact details
- Phone
- contact details
- Product
- Home insurance
- Consent
- Yes
A consent flag tells you what was recorded in the lead file. It doesn’t necessarily show the wording displayed or the interaction behind that answer.
What the evidence shows

- Evidence ID
- EV-91C2-7F4ALinks the lead to its signed evidence record
- Record integrity
- Signed, tamper-evident evidenceAn integrity check can detect changes to the signed record.
See how record integrity works.
Explore a sample evidence record, change a detail and run the integrity check to see how a modification is detected.
When consent is questioned, go back to the evidence.
Instead of relying on a consent flag alone, use the Evidence ID to examine the recorded interaction behind a disputed lead.
Find the Evidence ID
Locate the lead in your CRM and retrieve its associated Evidence ID.
Examine the record
Review the consent wording, recorded choice, timestamp and traffic assessment.
Investigate the dispute
Compare the evidence with the complaint to understand what was recorded and where questions remain.
Want evidence with the leads you buy?
AdPriva is designed to make consent evidence available alongside each lead, so buyers can examine the recorded interaction instead of relying on a consent flag alone.
We’re working with lead sellers and buyers to bring this workflow into existing lead-generation systems.

Why a CRM consent timestamp may not answer a buyer’s questions
What a consent timestamp can tell you, what it may leave unanswered and how additional evidence can help.
What if a lead arrives without an Evidence ID?
Ask your supplier whether an Evidence ID was issued for that lead. Without the ID or another supported lookup reference, you cannot retrieve its AdPriva evidence through the standard Evidence ID lookup.
