Submit a request to opt-out, suppress, or delete phone numbers from WhoCalledCheck records.
Verification & Processing Flow
To protect caller privacy and prevent unauthorized database opt-outs, all removal submissions are processed through the following validation steps:
- 1One-Way Cryptographic Hashing: Your submitted phone number is immediately converted into a secure SHA-256 hash. The plaintext number is never saved or cached in our databases.
- 2Format & Origin Verification: Our compliance filters run automatic checks to ensure dialing codes conform to E.164 standards, preventing automated scraper scripts from polluting our suppression logs.
- 3Permanent Suppression: Once approved, the cryptographic hash is permanently written to our global exclusion registry. Within 48 hours, all public query cached reports and future search lookups for the target number will be blocked automatically.
