Pesel
=====

This gem provides the Pesel class to check the PESEL number
and get information about its owner.

PESEL (Polish Powszechny Elektroniczny System Ewidencji Ludności,
Universal Electronic System for Registration of the Population)
is the national identification number used in Poland since 1979.

The PESEL number is mandatory for all permanent residents of Poland
and for temporary residents living in Poland for over 2 months.
Applicants for Polish citizenship must request a PESEL number together
with their passport application.
