Reassigned Numbers Database (RND): what it means in pay per call

Reassigned Numbers Database (RND): The FCC's database that tells callers whether a phone number has been permanently disconnected (and possibly reassigned) since a given date.

How it works in pay per call

If a consumer gave consent and later gave up the number, calls to the new subscriber are not covered by that consent. The RND lets callers check a number against a date (usually the consent date) before calling.

Under 47 CFR 64.1200(m), a caller that checks the RND and gets a 'no' answer has a safe harbor if the database turns out to be wrong. RND subscriptions are sold in monthly query tiers, from $8 for 1,000 queries; see our RND pricing page for all tiers.

Example

Example: a lead consented on March 1. Before calling in October, you query the RND with that date. A 'yes' means the number was disconnected after March 1, so the consent may belong to someone else; suppress it.
