This is good to know. If you're comfortable sharing, could you email me your VoIP provider or a phone number they're sending from? Address is in my profile. I'd like to learn more. For anyone else reading, this service is called "10 Digit Long Code" AKA 10DLC. Many business-oriented VoIP providers eventually use a vendor like Syniverse or Sinch for the outbound SMSes. Those wholesale carriers usually either strongly encourage their customers to require verification of sending numbers, or outright require it in the contract. This appears in the wholesale carriers' guidance to their customers, like https://syniverse-web.s3.amazonaws.com/10DLC-Carrier-Pricing-and-Policy-Info-Consolidated-Updated-02082023.pdf https://syniverse-web.s3.amazonaws.com/10DLC-Carrier-Pricing... and https://www.sinch.com/sites/default/files/file/2023-03/Inteliquent-Messaging-Best-Practice-Guidelines-2022-09-21_0.pdf https://www.sinch.com/sites/default/files/file/2023-03/Intel.... From your experience, it's clear that there are exceptions.

SMS enabling offnet numbers has gotten stricter over the last few months, Bandwidth.com will not enable wireless numbers for SMS, and if there is an existing routing record (eSPID/NNID) most vendors require this be removed by the losing SMS provider prior to enabling a number for offnet SMS. I used to be able to SMS enable my T-Mobile numbers offnet, but every 30 days TMobile would take this back. 10DLC is being strongly pushed by some carriers, while others are still permitting conversational traffic (for every one message that goes in, one should come back, with a 10% margin in either direction) to go over P2P rails. With The Carrier Registry invalidating all registered organizations and campaigns every few months, triggering everyone to fill out a ton of paperwork, pay $50 or more to re-validate every business, and also the recent sudden devalidation of every sole proprietor 10DLC registration, I don't blame those who don't want to participate in this unsanctioned cartel formed by the big three wireless carriers.

I’m going to confirm I can still use a number that’s not in my “block” from them, and if so I’ll tell you who it is…. I haven’t had it on my cell number in at least 6 months.
