Does AWS (Amazon Cloud) Block VoIP Numbers?

If you're trying to verify a AWS (Amazon Cloud) account and aren't receiving the SMS code, it's likely because you are using a virtual number.

Service Status: ISSUES
Common Error Message:
"We could not verify your phone number."
Why this happens:

AWS (Amazon Cloud) queries the telecom database (HLR Lookup) to identify the carrier associated with your phone number. If it returns as a "Non-Fixed VoIP" or "Virtual" number, the SMS gateway deliberately fails to send the text message to prevent fraud and spam. Often Flagged.

How to bypass AWS (Amazon Cloud) VoIP blocks?

Trying to find a "VoIP bypass" for AWS (Amazon Cloud) is a common mistake. Verification systems provided by companies like Twilio or Vonage are extremely efficient at detecting virtual numbers. The block is enforced at the network level, not the app level.

To successfully receive a verification code for AWS (Amazon Cloud), you need a number that is issued by a genuine Mobile Network Operator (MNO).
