About this topic archive
Signalmash publishes on US business messaging and voice: 10DLC and toll-free registration, short codes, RCS, SIP trunking, Branded Caller ID and the carrier rules that sit behind all of them. Topic pages like this one group every article that touches a single subject so you can read the whole thread in order rather than piecing it together from the main blog index.
Articles here are written by the team that runs the platform, and are revised when carrier requirements or pricing change. Where a piece covers a live compliance process, it links to the underlying documentation so you can check the current rule yourself.
Start with the fundamentals
If you are new to the subject, these guides cover the ground most questions come back to: 10DLC registration, brand to campaign approval, choosing between short code, 10DLC and toll-free, and what A2P messaging compliance actually involves.
