# 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:
Filter for just list membership returns 932 people
Filter for list membership and an phone number exists return 894 people
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.
