Law / PESEL number, passport, and ID in Poland [16]

As a foreign company (Dutch) I am told I need to request a PESEL number for sending documents electronically to KRS. The Polish embassy in my country told me to fill in the PDF document at obywatel.gov.pl/dokumenty-i-dane-osobowe/uzyskaj-numer-pesel-dla-cudzoziemcow Where do I need to send this document to in Poland? The embassy in Netherlands said I need to contact Dutch embassy in Poland and they don't know and referred me back to ambassy in Netherlands. Catch-22 situation. Now what is the address I need to send this document to?
