A2P 10DLC (Application-to-Person 10-digit long code) is the US carrier registration that is required for a business to send text messages to customers using standard 10-digit local numbers. Registration ties your messaging activity to a verified Brand (your business identity) and one or more Campaigns (how you plan to message), which helps carriers evaluate trust and reduce spam. While you submit the details through Patient Copilot, the actual review and approval process is handled by the US phone carriers and their registration partners. Carriers decide whether a Brand or Campaign meet the requirements and if the registration is accepted or rejected. Helpful Starting References: - What is A2P 10 DLC: Brand and Campaign Registration

Selecting the correct use case matters because carriers approve (or reject) Campaigns based on whether your messaging content, opt-in flow, and stated intent match the use case requirements. Carriers and messaging providers restrict certain content categories, even if your Brand and Campaign are approved. Avoiding forbidden content reduces the risk of filtering, account enforcement, and deliverability problems. For more information on campaign use cases, see: - A2P 10DLC Campaign Use Cases
