To protect consumers, U.S. carriers have implemented a 10 Digit Long Code, or 10DLC. This requires businesses that send SMS and MMS over local phone numbers to register their brands and campaigns with The Campaign Registry.

Brand and Campaign Carrier Registration

AT&T  |  AT&T requires Campaigns to be registered for each of the Brands with throughput restrictions based on the Campaign type and the use case. The Class assigned to a Campaign will place different surcharges with lower surcharges on a single-use case.

T-Mobile  |  T-Mobile has a daily allocation for throughput to the Brand. Allowance can be shared across all campaigns when a brand contains multiple Campaigns. T-Mobile holds single flat rates for surcharges.
