# People missing from Canvass or Call Time list

If you appear to be missing people from a list in Canvass or Call Time, and the number of people showing doesn't match what you see in NationBuilder, there's likely a good reason. Both Canvass and Call Time filter these list automatically for people who don't meet certain requirements.

### Requirements

#### Call Time

* Must have a valid phone number

#### Canvass

* Must have valid address
* Must be geocoded with mapping coordinates (check geocoding status [here](https://support.nationbuilder.com/en/articles/2308835-geocoding-addresses))

### How can I confirm, exclude or identify these people

You can run a NationBuilder filter that combines a condition of list membership with a condition that says a data point exists or does not exist, like so:

<figure><img src="/files/MdrhFNhQXXq3NuHw3ITf" alt=""><figcaption><p>Filter for just list membership returns 932 people</p></figcaption></figure>

<figure><img src="/files/twORrapW7vFhZRsCWyyX" alt=""><figcaption><p>Filter for list membership and an phone number exists return 894 people</p></figcaption></figure>

If the problem does not appear to be due to data requirements, it may be another factor like permissions that is removing them from the app completely. See [this article](/everything-else/other-guides/missing-people-or-organisations-in-people-section.md) for more information.
