# Why Is Marketing Data Missing for My Call?

> This explains why marketing data captured by the Invoca Tag can appear blank in call reporting, and how to investigate a specific call.

## Before you begin

You'll need the Call Record ID for the call you're investigating.

## Check the Media Type

Look up the call and check its Media Type to see whether the number is set to Pooling or static, and note which one applies.

## If the Media Type is Pooling

Check the promo number description for that call.

* If it's labeled "overflow," marketing data won't be collected for that call — overflow calls don't collect marketing data through the Invoca Tag.
* If the Invoca ID field is blank, the call is Out of Session, meaning blank marketing data is expected.

## If the Media Type isn't Pooling

Review the applied marketing data for the dialed Invoca number to confirm a value is present at the Profile, Campaign, or Phone Number level. If a value is present, check whether it was set before or after the call occurred — a value set after the call won't apply retroactively.

## What this tells you

If any of the conditions above are true for your call, that explains why Invoca didn't collect a marketing data value for it.
