«Customer Promises» of Public Transport Companies
The public transport companies within the association handle customer data confidentially.
The protection of your privacy and identity is very important to us at the public transport companies. We can assure you that we will process your personal data in accordance with the law and the applicable provisions of the data protection legislation.
As a sign of how seriously we take the confidential handling of your data, the public transport companies are committed to the principles below:
You are in charge of the decisions concerning the processing of your personal data.
Insofar as permitted by law, you can object to the processing of your data, withdraw your consent to data processing or have your data erased at any time. You always have the option of travelling anonymously, i.e. without your personal data being collected.
We provide you with added value when processing your data.
The public transport companies use your data exclusively for the purpose of delivering a service and providing you with added value all along the mobility chain (such as tailored offers and information, assistance or compensation in the event of a breakdown). This means that your data will only be used for the purposes of developing, delivering, optimising and evaluating our services or for maintaining the customer relationship.
We will not sell your data.
Your data will only be disclosed to selected third parties as referred to in this data privacy statement and only for the purposes explicitly stated. In cases where we commission third parties with data processing, we will obligate them to adhere to our data privacy standards.
We warrant that your data will be kept secure and protected.
The public transport companies assure you that customer data will always be handled with care and that your data will be kept secure and protected. We will ensure that the necessary organisational and technical arrangements are put in place to this end.

The legal basis for processing data at the ZVV
As a dependent institution under cantonal public law, the ZVV is subject to the data protection regulations applicable to public bodies of the canton of Zurich and to supervision by the cantonal data protection officer.
Consequently, the authoritative legislation for data processing at the ZVV consists, primarily, of the Information and Data Protection Act (IDG; LS 170.4) of the Canton of Zurich and its related ordinance (IDV; LS 170.41). In addition, the Federal Act on Data Protection (FADP; SR 235.1) and its related ordinance (DPO; SR 235.11) may also apply. Furthermore, the Federal Act on Passenger Transport (PBG; SR 745.1) contains special data protection provisions that must be observed by public transport companies.
Intersectoral cooperation in the area of ‘Direct Transport’
In its capacity as a public transport association, the ZVV is required by law to deliver certain transport services in conjunction with other transport companies (TC) and associations (‘Direct Transport’). The Direct Transport (DT) integrated transport system allows passengers to travel on the entire network with a single ticket even though it is operated by various TC and associations. Within this context, data is exchanged at a national level between the 240 TC and associations that are jointly responsible for maintaining the Direct Transport system across the whole of Switzerland. Personal data associated with DT products (specifically the GA Travelcard and the Half Fare Card) is stored in a central database that is managed by Schweizerischen Bundesbahnen, Hilfikerstrasse 1, 3000 Bern (SBB) on behalf of the Swiss public transport sector. If you use a SwissPass login, the data will also be stored in the SwissPass database that is likewise managed by SBB. To enable efficient service delivery and collaboration among the parties involved, the data from the various databases may be merged.
This centrally processed DT data is the responsibility of the ZVV together with the other TC and associations involved. The extent to which the individual TC and associations are able to access the shared databases is governed and restricted by a joint agreement.
Any data forwarding that takes place in the context of centralised storage and any processing undertaken by the other TC and associations involved in DT is, as a basic principle, restricted to the following purposes: contract processing, ticket inspections, after-sales service and revenue distribution. In addition, the data that you provide when purchasing Direct Transport services will – in certain cases – also be processed for marketing purposes. Specifically, this includes evaluation of the data so that the public transport services can be enhanced based on passengers’ needs and also promoted. In principle, such processing will only be carried out by the TC from which you purchased the relevant service. Processing for marketing purposes will only be undertaken by the other TC and associations in exceptional cases and under strict conditions. One exception to this is when SBB uses the data to get in touch with customers. SBB is responsible for marketing DT services on behalf of the Swiss public transport sector (specifically the GA Travelcard and the Half-Fare Card) and may contact you regularly in this role.
Purchasing travelcards and tickets
The following data is collected when you purchase a personal ZVV travelcard:
- Customer master data: gender (title), surname, first name, date of birth, address, telephone number, email address, personal customer number (CKM)
- Purchase data: type of travelcard, class, validity, place and date of issue, price
This data is stored in a central sales platform that is operated and managed by Schweizerische Bundesbahnen, Hilfikerstrasse 1, 3000 Bern (SBB) on behalf of the Swiss public transport sector. When you make a purchase via the ZVV ticket shop or the ZVV app, some of the data is also stored in the ZVV background system (back-end e-ticketing system) that is operated by MNC Mobile News Channel SA, Avenue de la Gare 10, 1003 Lausanne (MNC) on behalf of the ZVV.
When you purchase personal e-tickets (via the ZVV ticket shop or ZVV app), the following data is collected:
- surname, first name, date of birth and – where applicable – your personal customer number (if the purchase is linked to your ZVV customer account or if you use your SwissPass login)
- your email address – where applicable – for the purpose of delivering the tickets/sales receipts (some items of data are optional in the app)
- Purchase data: type of ticket, date/validity, place and date of issue, price
This data is stored in the ZVV back-end e-ticketing system that is operated by MNC on behalf of the ZVV. If you link your existing customer number when purchasing an e-ticket (purchases made via your ZVV customer account), the data will also be stored in the central sales platform operated by SBB.
If you use your SwissPass login to purchase services in the ZVV ticket shop or in the ZVV app, your customer data will be retrieved directly from the SwissPass database and stored in the ZVV back-end e-ticketing system.
For data processing when using the check-in function in the ZVV app, please refer to the explanations in the chapter ZVV check-in ticket.
As a basic principle, the data will be stored for as long as the associated services remain usable and refundable to ensure that the after-sales service can function in any eventuality. The data will then be anonymised or erased.
The ZVV does not store details of the payment methods used for purchases or for orders placed in the ZVV ticket shop or ZVV app. This data is stored directly by the payment service provider: Datatrans AG, Kreuzbühlstrasse 26, 8008 Zurich (Datatrans). The transaction reference number will be stored, in an anonymised form, in the ZVV back-end e-ticketing system that is operated by MNC Mobile News Channel SA, Avenue de la Gare 10, 1003 Lausanne (MNC) on behalf of the ZVV.
If you select the ‘Kauf auf Rechnung’ (‘Purchase on account’) payment method when purchasing a travelcard in the ZVV ticket shop, the payment will be handled by Byjuno AG, Industriestrasse 13C, 6300 Zug (Byjuno) on behalf of the ZVV. In this case, the data required for invoicing will be collected and processed by Byjuno directly. Outstanding debts from purchases on account will be collected by Intrum AG, Eschenstrasse 12, 8603 Schwerzenbach (Intrum) on behalf of the ZVV. For this purpose, the ZVV or Byjuno will forward all necessary personal and billing data to Intrum.
ZVV check-in ticket
- Customer data: surname, first name, date of birth, mobile number and email address, device information (make and model, operating system, network operator, battery level and wifi signal), information about travelcards, user ID and IP address
Customer data is necessary for the purposes of processing the purchase and customer service, identifying passengers during a ticket inspection, issuing purchase receipts, factoring existing travelcards into the price calculation and communicating with customers. The data is temporarily stored locally on the customer’s end device and is transferred to Fairtiq when the customer registers or changes details. Furthermore, Fairtiq links the data with travel and purchase data (see below) for the purposes of calculating prices, processing purchases and providing customer service. Customer data is stored in Fairtiq as long as you continue to use the check-in function in the ZVV app. Otherwise this data will be deleted 12 months after the last trip taken. However, you can have this data deleted at any time (see Your rights), provided the ZVV does not require said data to defend its rights. By submitting the request for erasure, you expressly waive your right to make use of customer services and file complaints about your journeys.
- Travel data: route and price information ascertained on the basis of the registered check-in and check-out information (station/stop, time, device ID number), the location and movement data collected during your journey via your mobile phone’s location services and the travel options (timetable).
The travel data is used to display the journey. The ZVV app transfers the data to Fairtiq for Fairtiq to process in its backend. Together with customer and purchase data, the data is necessary in order to process the purchase, provide customer support and avoid cases of misuse (i.e. customers can be blocked when misuse is detected). The travel data linked with the customer and purchase data (see below) shall be stored for 12 months as, depending on the travelcard, customer enquiries can even be submitted after this period. The travel data shall then be anonymised.
- Purchase data: route/zone, date/time, product and price, including class of travel (first or second class).
The purchase data is generated on the central SBB sales platform when the transaction is processed (see Purchasing travelcards and tickets) and made available to Fairtiq in the form of reports. Fairtiq links the data with customer and purchase data in order to process the purchase, provide customer support and avoid cases of misuse (i.e. customers can be blocked when misuse is detected). The purchase data linked with the customer and travel data (see below) shall be stored by Fairtiq for 12 moths for the purposes of audits and as, depending on the travelcard, customer enquiries can even be submitted after this period. The purchase data shall then be anonymised.
- Payment method data: credit card details or data from other payment systems
The payment method data is not stored either by ZVV itself or by Fairtiq on its behalf. This data is stored directly by the payment service provider: Datatrans AG, Kreuzbühlstrasse 26, 8008 Zurich (Datatrans). For accounting reasons, the payment method data shall be stored in an anonymised form for 18 months in the backend of ZVV’s e-ticketing system, which is operated by MNC Mobile News Channel SA, Avenue de la Gare 10, 1003 Lausanne (MNC) on behalf of ZVV.
Fairtiq uses the anonymised travel and purchase data in order to improve the app and optimise the services it provides. Furthermore, the anonymous purchase data will be sent to ZVV from the central sales platform and added to its database of sales data. The data will be used to distribute revenue between the various transport companies and for statistical evaluations, analyses and customer surveys.
Delivery of information and notifications
The ZVV may use customer data for the purpose of delivering important information and details of special offers as well as other notifications (e.g. about a travelcard’s expiry or valid from date), provided that this is necessary and appropriate for fulfilling its legally defined tasks. In principle, such deliveries fall under the responsibility of the ‘Regular Customer Strategic Business Unit’ (Regular Customer SBU) that is managed by VBG Verkehrsbetriebe Glattal AG and PostAuto AG, Northern Region on behalf of the ZVV. For this, the Regular Customer SBU sometimes relies on external service providers (specifically for printing, packaging and dispatch).
Notifications concerning a travelcard’s expiry or valid from date in the form of an email, SMS or letter are delivered on behalf of the ZVV by MNC Mobile News Channel SA, Avenue de la Gare 10, 1003 Lausanne (MNC). MNC has commissioned Couvertic, Ackerstrasse 46, 8610 Uster with the printing and dispatch of letters. MNC retrieves the customer data required for dispatching the notifications from the central sales platform operated by SBB (for further details, see section Purchasing travelcards and tickets) and stores this in its own database. The data remains stored there for 18 months to ensure that customer support can be provided.
The regular ZVV newsletter is only sent to customers who have expressly subscribed to it (click here to learn more about the ZVV newsletter).
If you have a ZVV customer account, you can use it to change the settings for receiving notifications and offers at any time. You can also opt out of receiving information and offers from ZVV at any time by sending a message to this effect to the ZVV-Contact customer service team (send it by email to email@example.com or by post to ZVV-Contact, PO Box, 8040 Zurich).
When sending information and offers within the aforementioned context, the ZVV may also use customer data from the Direct Transport system (for further details, see section Intersectoral cooperation in the area of ‘Direct Transport’).
Inspections, travelling without a valid ticket, abuse
The activities associated with ticket inspections, the imposition of fines for travelling without a valid ticket (including their collection) and combating abuse at the ZVV are carried out on behalf of the ZVV by SBB (S-Bahn operator), VBZ (City of Zurich) and PostAuto AG (wider network area). Within this context, the ZVV and the commissioned transport companies specifically process the following: customer data, ticket and travelcard data, inspection data and, where applicable, further data associated with an abuse of the system.
For the purpose of implementing the scale of charges (increase in the fine in the event of a repeat offence within two years in accordance with the applicable legal and tariff provisions), all data that is collected in the context of incidents involving passengers travelling without a valid ticket will be stored for two years. The data will be stored in a national register of passengers caught travelling without a valid ticket that is operated by PostAuto AG, Bern (PostAuto) on behalf of the public transport sector. Within this context, the available data will be exchanged with other transport companies in Switzerland (and also across borders in the case of international tickets or concessionary passes). Where permitted by law, this also applies to the data of those who have been convicted of a criminal offence in connection with the use of public transport.
Fairtiq ensures the prevention of fraud on behalf of the ZVV by securing incoming payments in connection with the ZVV check-in ticket. To do so, Fairtiq verifies all trips taken based on fraud algorithms and any anomalies are reviewed manually by a fraud agent. If any misuse is discovered, the passenger will be prompted via SMS or email to change their fraudulent behaviour. If the fraudulent behaviour continues, the passenger will be blocked from any further use of the check-in function. This block will apply system-wide, i.e. across all domains that use the Fairtiq app. However, the operators of these additional domains (i.e. SBB, BLS and any other future users) will not be given any access to the corresponding data. All data held on passengers that have been marked as scammers and banned will be retained in Fairtiq for 24 months after the last trip. After this point it will be deleted or anonymised as described above. In the event of any uncertainty or objection with regard to any block or warning received for fraudulent behaviour, please refer directly to the Fairtiq fraud department (firstname.lastname@example.org) or our customer service ZVV-Contact (email@example.com).
ZVV-Contact customer centre
The ZVV-Contact customer centre is operated on behalf of the ZVV by the Verkehrsbetriebe Zürich transport company (VBZ). If you make contact with ZVV-Contact in writing, by telephone or via the contact form on the ZVV website, the employees of ZVV-Contact will collect and process the personal data that you disclose in the course of your enquiry, such as your surname, first name, address, email address, telephone number, and so on.

When you participate in competitions, the data you disclose in the course of participating will be stored and used (surname, first name, address, email address and – optionally – your title and telephone number).
In addition to this, the «Regular Customer SBU» – managed by VBG Verkehrsbetriebe Glattal AG and PostAuto AG, Northern Region – also runs regular ‘thank you’ campaigns for ZVV travelcard holders via (www.zvv.ch/danke). You can only participate in these campaigns if you have a customer account. The necessary personal data for these campaigns (specifically: the dispatch address) will be retrieved from the central sale platform operated by SBB (see the chapter Purchasing travelcards and tickets).
Participation in surveys
You will not receive an invitation to participate in a survey via your stored email address unless you have given your consent. If you have stated your willingness to participate in surveys, you may receive an email from the ZVV or from a commissioned market research institution inviting you to complete a survey. You will receive invitations of this kind no more than twice in the same calendar year.
Your title, surname, first name and email address will be used to send you an invitation by email. In cases where your personal details are passed on to a market research institution so that it can conduct the survey, these will be used for the survey only and for no other purpose, and will be deleted by the market research institution on completion of the survey.
Whenever you are invited to participate in a survey, participation (i.e. the process of completing the questionnaire) is always voluntary.
Regardless of whether the survey is conducted by the ZVV or by a commissioned market research institution, the evaluation process is always carried out anonymously, i.e. your personal data will never be stored together with your answers.
The ZVV maintains a Facebook fan page as well as a Twitter, an Instagram and a LinkedIn account so that it can communicate important information and news as well as interact with customers and other interested parties. The ZVV will always adhere to the data protection provisions when handling personal data, including within the context of its social media offerings. The ZVV will process data that you have disclosed voluntarily (e.g. in a comment or in a message) insofar as this is necessary for the purpose of responding to your concern or request.
The ZVV cannot control how the operators (Facebook, Twitter, Instagram, LinkedIn) handle the data stored on their platforms. The ZVV recommends that users of these social networks take a careful look at the relevant data privacy policies by following the links and that they make the appropriate personal settings to protect their data.
You have the right to submit an access request to find out from the ZVV whether data and, if so, exactly what data concerning you is being processed and for what purpose.
