Campus access for MIT community members

Vaccination and attestation

All MIT faculty, staff, and students must be up to date with Covid-19 vaccinations or have an approved exemption in order to work, live, and study on campus. In addition, all eligible MIT students, staff, faculty, and affiliates must receive a Covid-19 booster in order to maintain access to MIT buildings. See MIT’s vaccination policy for more details.


Members of the MIT community who are in Covid Pass and compliant with vaccination requirements can access campus buildings through any access point they used before Covid. See MIT’s Quick Guide to Returning to Campus for more information.

Campus access for visitors

Visitors are welcome to campus and must follow all MIT Covid policies while on campus. Visitors are guests coming to MIT to attend a meeting, repair equipment, tour campus or a lab, pay a social visit, drop off a catering order, etc.

Vaccination and testing

In order to access MIT’s campus and MIT-sponsored events via the Tim Tickets system (MIT’s visitor pass system), invited visitors and event attendees must provide contact information and attest to being up to date with their vaccinations against Covid-19 or having a religious belief or medical condition that prevents them from receiving the vaccine. Tim Ticket users who are eligible for a booster vaccination must also attest to having received the booster shot.

All other campus visitors and attendees of MIT-sponsored events are strongly encouraged to be up to date on their Covid-19 vaccinations, including a booster shot for eligible individuals, unless they have a religious or medical exemption.

Visitors are not required to have a negative Covid test before coming to MIT’s campus.


The general public is allowed in outdoor spaces and select indoor campus spaces; these include Building W20/Stratton Student Center (first floor and basement) and E38/MIT Welcome Center (first floor only).

Otherwise, only authorized visitors are allowed inside MIT buildings. Visitors may be authorized to access MIT buildings in the following ways:

1. Covid Pass holder escort

Visitors may enter non-residential campus buildings from any access point if accompanied by a Covid Pass user; such visitors should be accompanied by a Covid Pass user while inside campus buildings. Covid Pass users may host a reasonable number of visitors at one time (e.g., the number of people that they can practically escort during a single visit) and are responsible for their visitor(s) for the duration of the visit.

2. Tim Tickets for unescorted visitor access

Tim Tickets, MIT’s visitor pass system, allows Covid Pass holders to invite visitors to campus and issue them a digital pass, referred to as a “ticket.” Tim Tickets must be used to grant visitors unescorted access to MIT facilities.

Visitors using Tim Tickets must:

  • Provide their contact information (name, phone number, email address) for contact tracing purposes.
  • Accept MIT guidelines for campus access and agree to adhere to MIT rules and protocols.
  • Submit a daily health attestation.
  • Attest that they have been fully vaccinated against Covid-19 or have a religious belief or medical condition that prevents them from receiving the vaccine. Tim Ticket users who are eligible for a booster vaccination must also attest to having received the booster shot.

Authorized visitors in Tim Tickets will be given a QR code that grants access to MIT buildings and/or events.

Any current MIT employee can issue a Tim Ticket to an invited visitor who does not have an MIT ID and Kerberos account, using the Tim Tickets feature in the MIT Atlas mobile application (available for iOS 13+ and Android 7+) or via the Tim Tickets visitor administration website.

Unescorted access to MIT facilities via Tim Tickets is generally not allowed for visitors under the age of 18.

3. Covid Pass

Visitors in the following categories will be entered into Covid Pass and must comply with MIT’s vaccination requirements:

  • MIT visiting student/scholar/scientist and research affiliate appointments
  • Exchange or cross-registered students (OVC-facilitated)
  • Contractors and service providers whose work requires planned access to campus buildings

See additional guidance for:

K-12 programs and visitors: Programs hosting K-12 visitors/minors should review MIT’s K-12 students and programs policy. Note that children who are under 12 years of age must either be accompanied by a parent or guardian or be participating in a registered MIT K-12 program. As noted above, unescorted access to MIT facilities via Tim Tickets is not allowed for visitors under the age of 18.

Prospective undergraduate students: If you are interested in learning more about MIT and our campus, we host both online and in-person information sessions. There are also many resources on the Admissions website to help answer your questions and enable you to explore MIT on your own.

Other tour groups: Unescorted public group tours are not allowed inside campus buildings at this time. However, visitors are welcome to explore outside spaces on campus with our self-guided walking tour. Learn more about visiting the MIT campus.

Research visitors: The following policies for research visitors are in effect:

  • Visiting scholars and research affiliates: MIT allows Visiting Scientist/Engineer/Scholar and Research Affiliate appointments in accordance with our policies. To access campus, visiting researchers, like MIT students, faculty, and staff, will be required to be fully vaccinated (or have an approved exemption) and to participate in Covid Pass. For information about these appointments, see MIT Policies section 5.3.4 and 5.3.5.

    While this includes international visiting scholars and research affiliates, it is important to bear in mind that planning travel to the U.S. remains fluid and challenging. Visa processing times, for example, are likely to take longer than they did pre-Covid, and the government could impose at any time new restrictions on travel into the U.S. depending on public health trends in other countries and in our own country. The International Scholars Office can provide you with more information on a case-by-case basis about reasonable expectations regarding start dates for international visiting appointments. We ask for your patience and cooperation.
  • Visiting students: MIT is once again welcoming applications to the Visiting Students Program. For details about the program, please review the Visiting Students policy.

Residence halls and FSILGs: For visitors in MIT residence halls and FSILGs, please refer to the Division of Student Life guidance for undergraduate and graduate student residents.

Vendors, suppliers, and contractors: If you are a vendor, supplier, or contractor from outside the MIT community seeking to access campus buildings to provide support for research, educational, or operational activities, your MIT contact will need to seek approval from the authorized access approver for their school, department, lab, or center (DLC). You will receive instructions for using Covid Pass to comply with campus access requirements, or you will be directed to be escorted inside campus buildings by an authorized Covid Pass user. Please note that usage will be monitored, and misuse of Covid Pass may result in revocation of a user’s account.
