3G controls

2G means that only vaccinated and recovered persons have access to certain areas. With 2G plus, vaccinated and recovered persons must also have a ne­ga­ti­ve antigen test or PCR test. 3G is the German abbreviation for vaccinated (geimpft), recovered (genesen) or tested (getestet). If 3G applies, it is necessary to be vaccinated, recovered or tested.As the term is so handy it is usually not translated.

The 3G rule applies to uni­ver­si­ty operations. Only persons who are vaccinated, recovered or tested are allowed to participate. However, the 2G rule applies to practical sport courses within the frame­work of the teacher studies degree program in the subject of sport, in the minor subject of sport or in rehabilitation sciences, i.e. only vaccinated or recovered persons may participate. For the time being, a ne­ga­ti­ve PCR test certificate can be submitted as a substitute for immunization on a transitional basis. For more in­for­mation, please visit the website of the Department of Sports and Sport Science.

TU Dort­mund Uni­ver­sity is obliged to check this on campus. For leisure activities such as uni­ver­si­ty sports, the 2G rule applies. In the main cafeteria, the 3G rule applies for uni­ver­si­ty employees and 2G for guests. In addition, employees are subject to a 3G rule at the workplace as of 24 No­vem­ber. Employees and students must carry their 3G proofs with them in case law enforcement officials carry out checks on campus.

Employees are subject to 3G regulations at the workplace. At TU Dort­mund Uni­ver­sity, the direct superiors are responsible for the control. However, they may also delegate the task. The supervisor or the designated representative must document that a vaccination certificate, proof of recovery or a current ne­ga­ti­ve test result from a certified testing center has been presented. The green check mark is not sufficient. The checks must be documented. You can find a sample form for this in the Service­Portal.


Whoever aims to attend an event at TU Dort­mund Uni­ver­sity must be vaccinated, recovered or tested (3G). The same applies to employees who work on site. Proof can be a vaccination certificate, a certificate of the past positive PCR test (as proof of recovery) or a current ne­ga­ti­ve citizen test. Digitally observed self-tests are not suitable as a test certificate. TU Dort­mund Uni­ver­sity checks original certificates at check-in points since 4 October and issue a pass for the duration of their validity. This is done in the form of a green check mark in the TU app. Please note that green check marks are no longer issued for test results. This function is reserved for vaccination and recovery proofs only. TU mem­bers who cannot use the app can receive a sticker upon presentation of proof of vaccination.

TU Dort­mund Uni­ver­sity may only recognize vaccination certificates if a vaccine approved in the EU has been administered and the required number of vaccinations has been given. These are currently the four vaccines Comirnaty (BioNTech/Pfizer), Spikevax (Moderna), Vakzevria (AstraZeneca) and COVID-19 Vaccine Janssen (Janssen-Cilag). The Paul Ehrlich In­sti­tute publishes a list of approvals in­clu­ding alternative product names in third coun­tries.­ro­na­virus/co­ro­na­virus-content.html;jsessionid=9D7040A90326DC256999D37542D26333.intranet211?cms_pos=3

As a rule, two vaccinations must have been given; with the Janssen-Cilag vaccine, one vaccination is sufficient for full protection. After the last vaccination, 14 days must have passed before full protection takes effect. For those who have recovered, one vaccination is sufficient; it is considered directly as full protection.

Those who have been vaccinated with a different vaccine or who are not yet fully vaccinated should seek medical advice on booster shots. In the meantime a ne­ga­ti­ve test certificate from a certified testing center must be submitted to meet the 3G rule.

A certificate of recovery is a certificate of a positive PCR test, which may be issued by a testing center, a general physician or a regulatory authority. The certificate must show the identity of the person and the date of the positive test result. The proof is valid as long as the positive test result was at least 28 days ago, but no longer than six months. After that, proof of vaccination or a ne­ga­ti­ve test result from a certified testing center must be presented to satisfy the 3G rule.

A ne­ga­ti­ve test result is currently valid for a maximum of 24 hours after the sample collection. It must be a professionally performed antigen test or a PCR test from a recognized laboratory. Digitally observed self-tests are not suitable as a test certificate.

On 10 Au­gust, the federal and state governments decided that, as of 11 October, free citizenship tests will only be available to those who cannot be vaccinated. The basic decision behind this is that tax money should no longer be spent on cases where the alternative option is vaccination. Consequently, since the uni­ver­si­ty is funded by taxes, it must not offer free tests to students who could be vaccinated but refuse to be.  

As an employer, TU Dort­mund Uni­ver­sity is obliged to offer its employees at least two antigen tests per week. For this purpose, the uni­ver­si­ty receives self-tests from the state. More in­for­mation can be found at “Self-testing for employees”.


3G status only entitles you to attend events if you are asymptomatic. Anyone with symptoms suggestive of co­ro­na­virus infection will not be allowed to participate in on-campus classroom teaching. Symptoms include shortness of breath, new onset cough, fever, and loss of smell or taste. Please stay home and contact your primary care provider / general physician for testing options.


TU Dort­mund Uni­ver­sity relies primarily on a di­gi­tal pass in the TU app for 3G control of its mem­bers. A virus icon has been added to the top right of the tile campusID. If you tap on it, a green checkmark indicates that the 3G status has been checked centrally and is valid. For this purpose, vaccinated and recovered persons must present their proofs once at central check-in points. A green check mark is no longer issued for tested persons.

In exceptional cases, a sticker may be issued upon presentation of proof of vaccination. Those who are recovered and waive the app solution as well as those who were tested or guests must present their original proof at the entrance checkpoints if they choose not to use the app solution, as must guests. Since the check at the entrances is somewhat more complex, there may be waiting times in these cases.

All employees in Germany must present 3G certification at the workplace. At TU Dort­mund Uni­ver­sity, the direct superiors are responsible for checking this. However, they may also delegate the task. The supervisor or the designated representative must document that a vaccination certificate, proof of recovery or a current ne­ga­ti­ve test result from a certified testing center has been presented. For vaccinated employees, a single check is sufficient. In the event of recovery, the date of expiry of the six-month validity period must be noted, counting from the date of the positive PCR test. In principle, the originals of the immunization certificates must be checked once: A self-declaration is not sufficient, nor is a visual check of the green tick in the TU app. Individuals who are not or not yet fully immunized must provide their superiors with a current ne­ga­ti­ve citizen test no more than 24 hours old on each day of attendance at the workplace. Employees must carry the 3G certification with them at the workplace in case the law enforcement authorities carry out checks on campus.

Employees - like students and guests - are also checked by security personnel at the main entrances to the lecture hall and seminar room buildings. The Studierendenwerk Dort­mund also has to carry out 3G checks or 2G checks for its catering offers in the main cafeteria.

First you need to install the TU app on your smartphone and log in with your UniAccount in the tile campusID. With the update of 22 Sep­tem­ber, the new function is available.

In the Central Library check-in points are currently open at which you need to present an offical photo ID (UniCard is not valid) and your certificates. To collect the data, first your campusID is read in from the TU app or, alternatively, your username for the UniAccount (the UniAccount must be activated) is typed in. After that, your proof will be checked. If you present complete proof of immunization, you will be unlocked in the TU app without time limitation. Recovered individuals will be unlocked for up to six months after their positive PCR test. The type of proof/certification is not stored, only the duration of validity. If the obligation ends to control the 3G status on campus, the data is deleted within one month. Digital access authorizations will no longer be issued for test certificates. Persons who have a ne­ga­ti­ve test certificate must present their original document at the entrance controls.

There is a permanent check-in point in the Central Uni­ver­sity Library and at the service desk in the ITMC which can be visited without previous booking of an appointment.

The database stores in encrypted form the date when your original 3G proof was created. This makes it possible to calculate how long your 3G proof is valid. The first time you use the function in the TU app, you can view the privacy policy. You can revoke your consent to storage at any time. After the end of the control obligation, the data will be deleted within one month.

Only mem­bers of TU Dort­mund Uni­ver­sity who have a UniAccount can use the campusID function in the TU app. The TU app can be installed on smartphones that run on the iOS or Android operating systems. In exceptional cases, stickers can be issued upon presentation of proof of vaccination.  These must be pasted onto a photo ID and must be handwritten with first and last name.

Recovered individuals, who waive the TU app, as well as tested individuals and guests, must show their original certificates at the entrances. Since the checks may take a little longer in this case, there may be waiting times.

The green checkmark in the TU app and stickers can only be issued to mem­bers of TU Dort­mund Uni­ver­sity. Guests must present their original proof of status at the building entrances ("Slow Lane").

Since 4 October, the security service performs 3G checks at the main entrances of the eleven largest lecture halls and seminar buildings on campus from Monday to Friday during 7.30 a.m. and 8 p.m. To ensure that admission can take place as quickly as possible, a visual check of the status in the TU app or stickers will be carried out in a "fast lane". If you only have original documents with you, you will have to queue in a "slow lane".

The check will probably take place in the following eleven buildings: Au­di­max, Lecture Hall Building II, Seminar Room Building, Emil-Figge-Strasse 50, Central Library, Sports Building, Lecture Hall Buildings Physics/Chem­is­try, Mechanical Engineering I, Otto-Hahn-Strasse 14 and Chemical Engineering Building Complex (central area) (all North Cam­pus), and Lecture Hall Building I (South Cam­pus).

In buildings where the security service does not carry out checks at the main entrance, teachers must check the 3G status of students in their courses. Again, for efficiency reasons, there should be no check of original documents, only a visual check of the status in the TU app or the stickers.

Yes. Anyone who enters the lecture hall and seminar room buildings through the main entrance will be checked by security - regardless of whether they are employees or students. In general, everyone who attends events on campus must be checked. The Studierendenwerk also has to carry out checks for meals in the cafeterias.

In order to identify any forgeries, TU Dort­mund Uni­ver­sity also carries out random checks on the entries in the central database in addition to the visual checks of the green checkmark and the stickers. In doing so, the campusID or the UniAccount is used to query whether the person has previously presented a valid 3G certificate/proof at a check-in point for verification. If there is no entry in the database, the green checkmark or the sticker are demonstrably not being used legally.

Anyone who participates in an offer for which 3G proof is required without being immunized or having the required proof of testing, or who uses a foreign or falsified proof of testing or immunization to use or carry out an offer, commits a regulatory offense according to the regulations of the Co­ro­na Protection Ordinance. In such a case, the individual must be excluded from the offered course. The Co­ro­na Protection Ordinance also provides for a fine of up to EUR 25,000 for such regulatory offenses.

Manipulation of the 3G status or the di­gi­tal access authorization in the TU app will be reported to the law enforcement authorities. TU Dort­mund Uni­ver­sity will prosecute any violations under civil and criminal law.
