DLP Data Loss Prevention - 16 Digit Numbers - Credit Cards

Biggun

WE have implemented DLP in Audit mode but notice whenever a relatively large smartsheet is saved, one of our DLP engines/dictionaries is triggered due to there being 16 digit numbers inside the smartsheet that appear similar to credit card numbers.

I have been through the visible contents of a couple of these smartsheets but none of the contents match.

I assume there must be some data in the background or it could be the translation of 'date' field content.

Does anyone know what might be producing 16 digit numbers inside or in the backgrond of a smartsheet?

Thanks

The Sheet ID is a 16 digit number, I would guess that's what's triggering it. I'm assuming DLP is leveraging the Smartsheet API, and most endpoints on Smartsheet API include the Sheet ID as standard in the response.
