ReopenCU App

Follow these instructions to download the ReopenCU app and upload vaccination and booster documentation. These instructions also apply to the mobile and desktop versions.

What You Should Know

  1. You must have a green pass from the app to access campus buildings. Completing the steps will generate a greenpass, linked to building access permissions on your CUID. You do not need to show your pass to enter buildings.

  2. Users who do not want to change their app store location to the United States should use the web version.

  3. The first time you use ReopenCU, the app will request permission to use location services. Enabling location services is voluntary, but will improve contact tracing at Columbia by providing access to the SSID of your wireless network connection. This location data will only be used for contact tracing purposes to identify potential close contacts by identifying you and a timeline of the WiFi access points your device connected to. Data will only be collected when the app is open and you are connected to a Columbia wireless network.

Make sure you are using the latest version by updating in the App Store or Google Play.

Opting in or out of location services is your personal decision. If you do not enable location services for the ReopenCU application, you can continue using any of Columbia’s wireless networks and the app will not collect your data. You can also enable or disable location services manually through your iPhone or iPad settings or your Android device settings.

How to Use the App

ReopenCU is available for download from the App Store for iOS devices and Google Play for Android devices.

Open the app and log in with your Columbia UNI and password.

Everyone who returns to campus must sign the University Health Compact and be up-to-date with COVID-19 vaccines.

  • The app allows you to digitally sign the compact; select "Show/Hide Compact." Once you select "I Agree," the app will remember your choice.

In the My Checklist section, in the last check box for vaccination compliance, click either the "student" or "faculty/staff" link.

Students will then be asked to select "Morningside" or "CUIMC" and be routed to the appropriate student health portal to upload proof of vaccination. 

Note that processing immunization documentation may take up to 15 business days to process

Employees will see a form that asks for basic data about vaccination and allows uploading of one documentation file in either jpg, jpeg, png, or pdf format.

You must complete all fields before clicking "Submit" to upload your documentation.


Requesting an Exemption

Students can request a medical or religious exemption through the appropriate student health portal, Morningside, or CUIMC.

Employees can request an exemption for medical or religious reasons by selecting the "request exemption" checkbox. The next page provides information on how to submit the request. Reviews will be conducted by a panel of medical experts including a representative from Human Resources. If the exemption is granted, the My Checklist section of the app will have an automatic check mark.

The boxes in the ReopenCU app are updated once you finish the compliance steps, following the timeline described for each.

Completing the steps will generate a greenpass, linked to building access permissions on your CUID. You do not need to show your pass to enter buildings.
