Company Registration

​​​Companies on a contract to operate at O'Hare International Airport must first register with the Office of Compliance to create and establish an ID Badge Company Account. A Completed Employer Information and Authorization form (EIAF)  and a Letter of Intent are required to create a new ID Badge Company Account. The Letter of Intent is issued by the Primary Signatory of the sponsoring agency/tenant.

Where applicable, the Primary Tenant acts as the sponsoring agency for all sub-tenants, contractors, and vendors and must review, approve, and sign all ID Badging forms and applications. All new companies must confer with their sponsoring agency/tenant for approval and initial company setup. When submitting the EIAF and Letter of Intent, companies must designate one Authorized Signatory who shall serve as the primary link for the company and the ID Badging Office.

Tenant registration requires a completed Employer Information and Authorization Form (EIAF)​ and a Lease Contract Agreement to create a new ID Badge Company Account. Lease Contract Agreement must be obtained only from the City of Chicago Department of Aviation Real Estate Division.

The completed EIAF and Letter of Intent shall be submitted to the Compliance Office. Upon successful submission of the EIAF and Letter of Intent, Compliance Office will check with sponsoring Tenant (company/agency) to verify documents and new company. After verification of company, Compliance Office will send ID Badge Application to the designated signatory to complete (Handwritten) and have the sponsoring tenant signs it. The designated signatory will email Compliance Office to request an appointment date to come in for process.

New company registration and process may take 3-5 business days. The Office of Compliance phone number is (773) 686-3020.
