# Phone Filter: keep Google Maps businesses with or without a phone number

> The Phone Filter narrows your Google Maps Leads Scraper results by phone presence — keep only businesses that have a phone number, or only those that don't.

If you're building a cold-calling or SMS list, a lead with no phone number is useless. The **Phone Filter** narrows your Google Maps results by phone presence.

## What it does

The Phone Filter is a dropdown with three values:

| Value             | What it returns                           |
| ----------------- | ----------------------------------------- |
| `all` *(default)* | Every listing — no filtering.             |
| `with_phone`      | Only businesses that have a phone number. |
| `without_phone`   | Only businesses without a phone number.   |

## Where to find it

The Phone Filter is in your Squid's **Advanced Settings**. It defaults to `all`.

## What it costs

Set to `with_phone` or `without_phone`, it **adds 0.2 credits per kept row** (on top of the base 1 credit per row). Left at `all`, it's **free**. Rows it drops cost nothing.

## Use cases

* **Cold-calling and SMS campaigns → `with_phone`.** Only keep leads you can actually dial.
* **Auditing coverage → `without_phone`.** Find listings missing a contact number.

## Common mistakes

* **Some real businesses don't list a phone number** on Google Maps — `with_phone` will exclude them.
* **You pay per kept row.** Set to `with_phone` or `without_phone`, it adds 0.2 credits to every business you keep.
