Non-VoIP Number for Sparrow Card
Why Sparrow Card specifically wants a non-VoIP number
“Non-VoIP” is the exact technical distinction Sparrow Card'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 dedicated hardware line resolves as Mobile in every lookup database Sparrow Card queries, without needing a postpaid contract or a credit check to get one.
