Are all tools free without an account?
SPV’s public single-number tools describe limited free checks without signup. Bulk processing requires an account and funds in your wallet.
Can I use these tools for bulk lists?
Use the bulk validator and account workflow for CSV or Excel lists; single-number tools are designed for individual checks.
Why can a result have missing fields?
Number data and enrichment availability vary by market, number type and source.
Which tool should I use first?
Start with the phone validator when you need a general check. Choose a specialist tool when you need a specific field.
Does checking a number send an SMS?
SPV’s public description says the lookup does not call or text the number.
Can I automate these checks?
Use the documented REST API from your application rather than manually repeating individual checks.
Start with the numbers you have.
Check a single number, clean a contact list, or add validation to your app.
