Troubleshooting Verification Codes
Fix "code not arriving," "this number cannot be used for verification," and other common issues with JoltSMS. Start here if something isn't working—then jump into the detailed guides for each error.
Before you dive into a specific error, try these quick checks:
- Confirm you're looking at the right JoltSMS number in your inbox.
- Make sure the sending service is set to SMS (not voice or email).
- Wait a full 60 seconds and request the code again once.
- Avoid multiple back-to-back code requests, which some platforms rate-limit.
If that doesn't help, pick the issue that best matches what you're seeing below.

"This Number Cannot Be Used for Verification" Errors

How long should I wait for a verification code?
Most codes arrive within a few seconds. If you don't see anything after 60 seconds, refresh your inbox and request one more code. If multiple attempts fail, follow the Missing or Delayed Codes guide.

No provider can guarantee that—carriers and the sending platform control part of the path. We monitor delivery on our side, but some codes may be blocked or dropped; use the troubleshooting steps and contact support if you suspect a persistent issue.
