Thank you for your interest in doing business with the Chicago Transit Authority (CTA). If you are interested in doing business with the CTA, please click on the Create Account link below to be directed to the CTA iSupplier Portal where you can register as a vendor.
If you are an existing vendor who has been approved by the CTA, you can click on the link below to maintain your CTA Vendor information.
If you are a Disadvantaged Business Enterprise (DBE), by clicking the DBE Links below, you can complete the Disadvantaged Business Enterprise (DBE) Vendor Application and apply for Disadvantaged Business Enterprise (DBE) certification. Firms that are already listed in CTA’s vendor database may update or modify their DBE information. Furthermore, currently certified DBE firms can complete the forms necessary to maintain their certification with CTA.
All firms that are owned and controlled by disadvantaged individuals are welcome to apply for DBE certification. To be eligible to participate in the DBE program, your firm must be certified pursuant to United States Department of Transportation (US DOT) regulations which can be viewed on this web page. The specific regulations can also be found in 49 Code of Federal Regulation, Part 26.
Upon completion of each of the applications on this web page, your firm will also need to submit additional supporting documentation to the CTA. If requested supporting documentation is not submitted in a timely manner, your application will not be processed. You will be notified of the required documentation once you have completed your application. Any false or misleading information submitted by applicants will be grounds for denial, removal and/or prosecution.
We look forward to doing business with your firm and will give your completed application our prompt attention. You may view additional information related to the procurement process at CTA on our web page.
After logging in to your account, you will be directed to the application form. You can also click the Apply for Certification link on the right side of the "Dashboard." If you require technical assistance while completing the application, please use our online support form.
