Phone number ID
The long number Meta assigns to a registered WhatsApp number, used by software instead of the phone number itself.
Every number on the platform gets an ID. The business's software sends and receives through that ID, and each incoming message carries it, so one server can serve many businesses and keep them separate.
It is not secret, but the access token that goes with it is.
Why it matters
It is how Dunnflow routes a message to the right business's replies and nothing else.
