Top brands rely on Sinch to reach their customers
A 10DLC (10-digit long code) local number is a standard phone number, similar to a landline, that businesses can use to text their customers. They contain familiar local area codes—like 212-555-1234 for a business in New York City, NY, for example.
Sometimes called “A2P 10DLC messaging”—because 10DLC is the number type carriers have approved for A2P (application-to-person) messaging—these numbers are attractive to businesses because they’re an affordable way to send secure marketing and reminder messages both 1-to-1 and to large audiences.
10DLC vs. other number types
10DLC local numbers are cost-effective and cover most business use cases—from 1-to-1 support texts to large-scale notifications. They’re also faster to set up than short codes. See more about how the number types differ.
