A valid CERN card is needed to enter the fenced parts of the CERN site and certain controlled-access areas. In the latter case, access is also subject to having the relevant prior authorisations.
Different categories of card, allowing access to different places and at different times, are issued according to the cardholder’s status.
The conditions governing the issue and use of CERN access cards are explained in detail in Operational Circular No. 2 and its annexes.
This CERN card must be worn visibly. It is personal and only its owner is allowed to use it.
1. How to obtain a CERN card
The CERN card is issued to members of the personnel and contractors' personnel holding a valid contract, in the framework of the arrival formalities. They must go to the Registration Service (building 55) in person to obtain their card, bringing along their passport or identity card.
The different types of cards and their period of validity are defined in Annex II of the Implementation Measures of Operational Circular No. 2.
N.B. To facilitate arrival formalities, new members of the personnel can obtain a visitor card valid for 2 days and printable at home.
2. Extending the validity of the CERN card
3. Returning a CERN card
A holder of a CERN card who no longer fulfils the applicable conditions (e.g. when a contract, assignment or registration expires) must surrender the card, as well as any cards associated with it (e.g. those belonging to family members or accompanying persons), to the Registration Service (building 55).
4. What to do in the event of a problem?
Any problems concerning the CERN access cards and any cases of refused access to a CERN area, building or experiment should be reported by e-mail to the Access Control Service.
The loss or theft of a CERN card must be declared immediately via the Declaration of loss or theft or the Service Desk. Once the declaration has been made, the person concerned should go to the Registration Service (building 55) to obtain a new card. The other card is then blocked.
