Reassigned Numbers Database (RND) (FCC)
The Reassigned Numbers Database (RND) is a system mandated by the Federal Communications Commission (FCC) in the United States. It helps businesses and organizations avoid calling phone numbers that have been reassigned to a new consumer—which helps reduce unintended robocalls and ensures compliance with TCPA (Telephone Consumer Protection Act) regulations.
✅ What is the RND?
Purpose: To prevent calls and messages to consumers who did not consent to be contacted.
Problem Solved: When a consumer gives consent and then gives up their number, the new owner of that number may receive unwanted calls. The RND helps avoid this by letting callers check if a number has been reassigned since a given date.
Who Uses It: Businesses that make outbound calls or texts (e.g., for marketing, collections, customer service).
? How to Use the Reassigned Numbers Database
1. Register Your Business
Go to the official RND website: https://www.reassigned.us
Create an account by providing your organization's information and purpose for querying.
2. Submit a Caller Profile
Define your business use case and confirm compliance with TCPA requirements.
Include the list of phone numbers you're checking and the date the consumer provided consent (called the “query date”).
3. Upload Number Lists
Upload phone numbers to the portal via:
Manual CSV upload
API integration (for automated systems)
4. Check the Results
The system will return one of three responses per number:
Yes – The number has been reassigned since the query date.
No – The number has not been reassigned.
No Data – The system has no information about the number.
5. Take Action
Avoid calling numbers with a "Yes" result to remain TCPA-compliant and avoid potential fines.
⚠️ Important Notes
There are usage fees for querying the database (based on volume).
Compliance is especially important for businesses using autodialers or mass-texting platforms.
