Distributors will generally report sales data to manufacturers.
What is reported may vary. You may get specific stuff like "Serial numbers 1,2,3 were shipped to Address Y, Serial numbers 4,5,6 were shipped to Address Z, etc." This would also contain any reference numbers for things like project registrations. Or, you may get "(x) units of model (y) were sent to this zipcode, (x) units of model (z) were sent to this zipcode, etc."
Generally the manufacturer can define what information they want to get from the distributor. While that same info may also be sent to rep firms, it is not a given, and may flow through the manufacturer.
If you want attention from your regional guy you may need to ask for it, and/or possibly escalate the issue with the manufacturer. Ideally your sales volume is automatically recognized and the right people reach out to engage you, but this does not always happen. It can be a lazy rep, or it can be a case where the rep is stretched thin and underfunded in the sense of not having time and budget to meet with you vs. meeting with larger accounts, or meeting with accounts that need more attention and hand-holding.
