# Business registration and number health

> What a verified business profile does for your rented numbers, what it cannot promise, and how Fuse protects your calling reputation by retiring unhealthy numbers.

A business profile connects your company's verified identity to the numbers you rent through Fuse. It is what turns an anonymous phone number into one that networks associate with your business.

Caller verification, named calling and reputation registration currently apply to US numbers rented through Fuse.

## What registration supports

| | What it does |
| - | - |
| **Caller verification** | Helps phone networks recognize that calls are legitimately associated with your business |
| **Named calling** | Displays your business name as the caller ID name on supported devices and networks. On by default; you can turn it off |
| **Number reputation** | Reduces the likelihood of legitimate calls being treated as suspicious or mislabeled as spam |
| **Regulatory compliance** | Every rented number needs a business profile first, and most countries outside the US and Canada also need it approved. See [Before you rent](/dialer/phone-numbers#before-you-rent) |

<Warning>
  **Use accurate details.** Your legal, registration, address and representative information all need to be correct and consistent. Incorrect or inconsistent details may delay approval, or prevent it.
</Warning>

## What registration cannot do

Registration improves your trust signals. It does not control what happens at the other end of the call.

It cannot guarantee answer rates, that your caller name is displayed, or that your calls are never labeled as spam. Each receiving network makes its own display and filtering decisions.

## Number health

Fuse rates each number, rented or owned, from its last 30 days of calls: **Excellent**, **Good**, **Weak** or **Unsatisfactory**. A number with fewer than 20 calls in that window shows **Insufficient data** and stays in rotation. Fuse warns you as a number's score falls, and again when it is taken out of rotation.

A number rated unsatisfactory shows as **Direct dial only**. Fuse stops picking it automatically for new contacts, which helps protect your calling reputation, but you can still select it yourself for single dialing. Fuse also still reuses it for [contact continuity](/dialer/number-selection#contact-continuity-comes-first), for contacts who have answered a call from it before.

<Warning>
  **If every number available to you is rated unsatisfactory, Fuse pauses dialing**, even for a number you pick yourself. It resumes once you add a new number, rented or owned, or once your existing numbers recover.
</Warning>

If dialing has paused and it is not clear why, [contact support](mailto:support@fuseai.com).
