5 checks that get you approved

Welcome. If you text customers from a 10-digit number, A2P 10DLC registration isn’t optional: unregistered traffic gets blocked. The good news is that most denials come down to the same handful of fixable mistakes.

Here’s the short version. Each weekly issue goes deep on one of these, with the exact wording to use.

Before you submit, check

•

Opt-in you can prove. Who signs up, where, the exact words they see, and how they confirm (30896/30917).

•

The 4-part disclosure. Message type, frequency, “Msg & data rates may apply,” “Reply STOP,” with an unchecked box (30924/30925).

•

Samples that match your use case, with your brand name, [bracketed] variables and no link shorteners (30893/30892).

•

A privacy policy SMS clause saying opt-in data is never shared or sold (30908/30932). And a brand that matches the IRS exactly (30894).
