A2P 10DLC (Application-to-Person 10-Digit Long Code) registration ensures that carriers approve your messages before being sent, significantly reducing the chances of your texts being blocked.
What Is 10DLC?
A 10-digit long code, or 10DLC, is a special number that allows organizations to send application-to-person (A2P) messages to their customers in a way that’s fully approved by U.S. wireless carriers. It looks just like a regular phone number, so when your recipients receive an SMS message, it appears completely normal to them.
Why do you need a 10DLC Registration?
Compared to regular long codes, because 10DLCs are approved by the carriers before they're used the text messages sent on these 10DLCs are much more likely to reach recipients without being terminated or flagged as spam first.
Here’s why this matters:
- Higher Deliverability – Carriers are constantly filtering messages to reduce spam. Without registration, your messages may be delayed or blocked altogether. Registered 10DLC numbers are pre-approved, meaning they’re more likely to reach customers successfully.
- Lower Filtering & Message Failures – Unregistered numbers have a higher chance of being flagged for potential spam, even if your messages are legitimate. Registration tells carriers that your business is verified and you're sending authorized communications.
- Better Messaging Reputation – Carriers track the reputation of phone numbers. A registered 10DLC number builds trust over time, making it easier to send messages reliably without random blocks.
- Compliance with Carrier Rules – Many U.S. mobile carriers are tightening restrictions on business SMS to prevent abuse. By registering your 10DLC, you comply with these evolving regulations and reduce the risk of future disruptions.
