Why Grubhub Restricts Virtual & VoIP Phone Numbers
Grubhub uses automated fraud detection tools to block disposable phone numbers and protect diner loyalty rewards. When an unverified VoIP number is submitted, Grubhub flags the order or stops driver registration. USAVerify Pro provides genuine physical SIM lines with legitimate carrier metadata to ensure complete compliance.
