<agencycode> Agency Code

<agencycode> is a new element in EAD3 and an optional child element of <maintenanceagency>, used to supply a code for the agency responsible for the creation, maintenance, or dissemination of the EAD finding aid. For best practices, use the format of International Standard Identifier for Libraries and Related Organizations (ISO 15511). The code is composed of a prefix, a dash, and an identifier. For specific codes, see the Library of Congress’s code search.

When used in combination with <recordid>, <agencycode> can provide a globally unique identifier for the finding aid. The agency’s name should be encoded in <agencyname> with <otheragencycode> used to designate any non-standard codes.
