Carriers have certified a phone number when you use a standard landline or VoIP number to send SMS text messages.
The current status of using a long code, a regular 10 digit phone number, to send a text message allows subcarriers or aggregators to send SMS text messages bypassing the mobile carrier network.
Carriers are now moving towards pushing SMS marketers to use “approved” 10 Digit LongCode so that they can control the costs and easily identify the sender for the originating SMS traffic. 10DLC is managed by mobile carriers and they have full control of the eligibility of sending messages, the content of the messages, and throttling rates for delivery.
