Why This Rejection Happens
Your sample messages contain a public/shared URL shortener (e.g., bit.ly, tinyurl.com, goo.gl). These domains are strictly prohibited on 10DLC because they are commonly used by bad actors to hide phishing links.
Root Cause Analysis
Carrier Policy: Carriers cannot see the destination of a public short link without clicking it. To protect subscribers, they block these domains at the network level.
Prohibited Domains (Examples)
- ✗ bit.ly
- ✗ tinyurl.com
- ✗ goo.gl
- ✗ ow.ly
- ✗ is.gd
- ✗ rebrand.ly (free tier)
The Fix

Option B: Branded Shortener
