Reassigned Phone Number API - api_rnd
Searchbug offers an API service that provides access to the FCC Reassigned Numbers Database. On January 27, 2021 all service providers were required to start maintaining records of disconnected numbers. By submitting a phone number and the last date of consent to contact the consumer, you can quickly determine if the number has been reassigned or disconnected after that date.
The FCC provides a "safe harbor" for businesses using the national database. If you check the database and call a number that has not been reported as disconnected, you are protected from TCPA liability. Perform an RND query on phone numbers before contacting them to ensure you are reaching the intended recipient and stay compliant.
You can submit up to 1000 records at a time with a POST request.
Cost is 0.04 to $0.01 per query, depending on volume.

Frequently Asked Questions (FAQs)
What is the People Search API used for?
The People Search API helps businesses, investigators, and legal professionals verify identities, find contact details, and enrich their databases with accurate information. It’s often used for lead generation, background verification, KYC processes, and customer record enhancement.
What are the "Find" APIs used for?
The Find Name and Address, Find Phone Number, and Find Email APIs are used for many of the same purposes as the People Search API. The main difference is the quality and source of the data. As such, these APIs are generally used more for general marketing purposes.
How to find a name from a phone number?
Our People Search API and Find Name and Address API allow users to search by phone number to identify the owner’s name and address. It’s ideal for businesses needing to validate customer data or track down missing information.
Is this API suitable for KYC compliance?
Yes! The People Search API is often used in KYC processes to confirm customer details before onboarding. Financial institutions, insurance companies, and compliance teams rely on this API to meet regulatory requirements.
How do I pay for API services?
All of our APIs work off of a prepaid balance. First, you load your account with a predetermined amount of funds between $10 and $5000. With each API call, the system will slowly chip away at your prepaid balance. When the prepaid balance gets low, the system automatically replenishes your balance with the predetermined amount.
To add a prepaid balance, log into your account and click your name at the top > select 'Your Account' from the dropdown menu > under the 'Billing Details' section click 'SWITCH PLAN'.
How does the API pricing work?
When a query is successful (called a "hit"), charges apply. There is no charge if there is no information found on a query. The cost per hit decreases as your monthly volume increases, making it cost-effective for businesses handling high search volumes.
Can I test the API before purchasing?
Yes! We offer free API testing for qualified users. Register for a no-obligation Sandbox API Test Account, and you’ll receive a limited number of live queries to evaluate the quality of our data before fully integrating.
How often is the data updated?
Searchbug utilizes sophisticated algorithms to search a multitude of data sources to ensure the contact data quality is always fresh, accurate, up-to-date, and never stale.
