Every new 10-digit long code (10DLC) campaign and toll-free vetting submission now goes through Bandwidth vetting. Wireless carriers found that many application-to-person (A2P) senders registered their campaigns incorrectly or didn’t follow the carriers’ codes of conduct. Vetting closes that gap.
Bandwidth pre-screens each submission before it reaches our vetting partner for further review. That gives you feedback early, when it’s easiest to act on.
This guide lists every error code you may receive from Bandwidth vetting, organized by messaging channel. A single campaign can receive several rejection codes at once. You get the full picture in one pass, so you can bring your campaign into compliance with confidence.
Toll-free vetting rejection codes are here, so you can prepare before vetting begins on February 2, 2027. 10DLC vetting is already live for every submission.
Know your code prefixes
Each prefix tells you which route a rejection came from:
Toll-Free: Codes start with TF- (for example, TF-2100).
10DLC: Codes start with 10DLC-.
