# Register phone numbers for reputation monitoring

> Add up to 100 phone numbers to reputation monitoring on this enterprise. Each must be in E.164 format (`+1NPANXXXXXX` for US/CA) and belong to your Telnyx phone-number inventory.

**Prerequisite**: reputation must already be enabled on this enterprise (see `POST .../reputation`).

**Pricing:** This is a billable action. See https://telnyx.com/pricing/numbers for current pricing.
