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 IANA PEN Registry.
There is no fee for obtaining a PEN assignment. Please allow up to 30 days for your application to be processed.
If you are not sure whether your organization has registered a PEN, please check the registry. If your organization does have a PEN, we recommend obtaining a sub-assignment from the contact listed in the registry.
