Frequently asked questions

Who can use Cosign?
Anyone can browse listings. To post a listing or message another student, you need to verify your Howard University affiliation with a @bison.howard.edu or @howard.edu email, or by uploading your student ID.
How do I verify my Howard affiliation?
After signing up, go to your profile and start verification. We'll send a magic link to your Howard email address. If you don't have access to your Howard email, you can upload a photo of your student ID instead.
Is Cosign free?
Yes. Cosign is free to use for Howard students. There are no listing fees, no subscription charges, and no commissions.
How do I report a suspicious listing?
On any listing detail page, scroll to the bottom of the sidebar and click "Report this listing." We review every report and will remove listings that violate our guidelines.
When does the platform open?
Cosign opens to Howard students in August 2026. Join the waitlist to get notified the moment it goes live.
