Your processing purpose.

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.

Is this phone number validator free?
SPV advertises limited free individual checks and 100 free lookups for new accounts.
Does a valid number confirm the owner?
No. Use a separate ownership verification step when needed.

No. Channel support and network conditions still affect delivery.
What should I enter into the checker?
Enter a phone number with its country calling code, such as an international +code format.
What does an invalid result mean?
The number failed available checks. Review the reason and ask for correction where appropriate.
Can I check a CSV or Excel file instead?
Yes. Use the bulk validator through an SPV account. It takes CSV and Excel (.xlsx) files.
