404X serial number distinction

Hardware
1

Hello!
I just have a simple question:

It appears to me that the B404x serial numbers begin with “P” whereas the previous Boron serial numbers began with “B”.
Is this a correct assumption?

If not, what is the best way to distinguish between the two remotely?

Thank you in advance!

Here’s a great tool you can use to check the actual SKU: List devices | Tools | Particle

B404X starts with P042 and BRN404X starts with P044, but that may not always be the case and I would use the SKU tool.
