Non-VoIP Number for Sardine.io
Why Sardine.io specifically wants a non-VoIP number
“Non-VoIP” is the exact technical distinction Sardine.io's carrier-lookup check is looking for: a line-type classification of Mobile or Landline, not VoIP. This isn't arbitrary — VoIP numbers can be provisioned instantly and near-anonymously, which is exactly the profile fraud and spam accounts share, so gating on line-type raises the cost of abuse without requiring a full ID check. A real mobile subscriber line resolves as Mobile in every lookup database Sardine.io queries, without needing a postpaid contract or a credit check to get one.
