Twilio Error 30007: Carrier Filtered — Why It Happens & How to Fix
Error 30007 is a carrier-side filter — Twilio sent the message but the destination carrier blocked it. Causes range from unregistered A2P traffic to specific content flags.
Top 5 causes of 30007
- 10DLC traffic from a number not associated with an approved campaign (more often surfaces as 30034 directly).
- Public URL shorteners (bit.ly, tinyurl) in the message body.
- SHAFT-C content (sex, hate, alcohol, firearms, tobacco, cannabis) without proper age-gating.
- High volume to a single recipient triggering flood detection.
- Recipient previously replied STOP and your service didn't honor opt-out.
