Serial number help! 3.2
 

Hey guys.

So in my bonnet under the carpet below smugglers box my serial number is

WPOZZZ91ZFS.......
But on my A pillar and door jamb it is
WPOEBO919FS........

This car has no accident history and here is where it gets interesting

The remaining 6 serial numbers are the same in both cases
And the engine serial matches USA car so......

Any help or ideas?

Solved. Thank you. For anyone wondering - it's a chassis stamp used until porsche determined the market

Thanks
