Clear data practices. Clear responsibilities.
Review how SPV describes customer-data processing before introducing it into your workflow.
Your numbers.
Your processing purpose.
SPV’s published policy states it processes submitted data to deliver the requested service and does not sell submitted personal information.
Read the privacy policyPrivacy and data protection
The policy addresses GDPR and UK GDPR, data-subject rights and international transfers. Customers remain responsible for their lawful basis for processing.
Retention and security
Retention varies by purpose and legal requirements. Review the published policy and ask the team for retention periods and the controls relevant to your deployment.
Validation and outreach consent
A valid number does not establish permission to call or text. Apply your consent, suppression and channel-specific checks separately.

What is a bulk phone validator?
It processes a list of phone numbers and provides per-number validation results instead of requiring individual manual checks.
How much does a list cost?
One lookup per unique number, at $0.004 each. If the same number appears more than once in a file, it is charged once. Your account needs enough funds for the list before the job starts, and your free lookups are used first.
Does the validator remove numbers from my list?
No. Every row comes back with its result. Review the output and apply your own policy before re-importing.
Which file format does SPV support?
CSV or Excel (.xlsx) uploads. In the dashboard we show your columns and you choose the one with the phone numbers. Through the API it is found automatically when named phone, number, mobile or tel, or you name it with phoneColumn.
Does a bulk job run in the background?
Yes. You can leave the page while the list is processed. We email you when the results are ready to download.
Does the file preview on this page upload my file?
No. The preview counts rows locally in your browser. Use your SPV account for actual validation.
