Private Enterprise Number (PEN) Request
To request a Private Enterprise Number (PEN), typically used in Lightweight Directory Access Protocol (LDAP) and in Simple Network Management Protocol (SNMP) Management Information Base (MIB) configurations, please complete the application provided below. The required fields are marked with an asterisk (*). Only the contents of the Organization Name, Contact Name, and Contact Email fields will be published in the PEN Registry.
