For immediate assistance, Slott provides dedicated telephone lines staffed by multilingual representatives. The main customer service number is reachable from within the Netherlands at 0900 – 80 80 (€0.10 per minute). International callers can dial +31 30 232 08 08. Lines are open Monday through Friday from 09:00 to 21:00, on Saturday from 09:00 to 17:30, and on Sunday from 10:00 to 17:00. These hours apply to general inquiries, booking modifications, and ticket cancellations. For group travel or business account support, a separate phone line is available at +31 30 232 08 88, operating on weekdays from 09:00 to 18:00. Please have your booking reference or account number ready when calling to expedite the process. All calls are recorded for quality and training purposes.
Written correspondence can be directed to Slott's customer service email address: [email protected]. This mailbox is monitored during business hours, and responses are typically sent within 24 hours on weekdays. For urgent matters related to active travel, it is advisable to use the phone line, as email replies may take longer during weekends and public holidays. When composing an email, include your full name, booking number (if applicable), and a clear description of your question or issue. The team handles inquiries in Dutch, English, German, and French. For complaints or feedback that require escalation, use the dedicated address: [email protected]. This inbox is reviewed by a senior customer relations officer.
An alternative to direct email is the contact form available on the official Slott website. The form can be found under the "Contact" section (navigate to slott.com and locate the envelope icon). It requires you to select a category – such as "Booking Help", "Payment Issue", "Technical Support", or "General Question" – and then provide your name, email address, telephone number (optional), and your message. The form automatically assigns a reference number, which is sent to you in a confirmation email. Using the form can help route your query to the appropriate department without manual sorting. Response times are comparable to email, typically within one working day.
Slott's headquarters is located in Utrecht, the Netherlands. The mailing address is: Slott Reizen B.V., Stadsplateau 15, 3521 AZ Utrecht, The Netherlands. This is the registered office for all written correspondence and legal documents. Walk-in customer service is available at the same address from Monday to Friday, 09:00 to 17:30, by appointment only. To schedule an appointment, you must call or email in advance. The office is situated near Utrecht Centraal railway station, making it accessible for travellers. Please note that the walk-in desk handles only issues that cannot be resolved by phone or online, such as refunds requiring physical signatures or lost ticket inquiries.
While Slott does not operate a public chatbot, its customer care team monitors messages sent via official social media profiles. The company is active on Twitter (handle @Slott), Facebook (Slott Reizen), and Instagram (slott_nl). Direct messages sent to these accounts are reviewed during business hours, though response times can vary depending on volume. The social media team generally deals with general information requests and light troubleshooting; complex booking changes or payment disputes should be handled through phone or email for security reasons. Slott also maintains a LinkedIn company page for professional inquiries, but that channel is not intended for customer service.
For postal letters, including formal complaints, invoices, or legal notices, the address is the same as the physical office: Stadsplateau 15, 3521 AZ Utrecht. Billing-related questions should be sent to the accounting department via email at [email protected], or by post marked "Finance – Accounts". Please include your customer or invoice number in all financial correspondence. Slott does not accept cash payments at the office; all payments must be made through the official payment channels provided in your booking confirmation. If you have a specific question about a credit or debit card transaction, the finance team can be reached by phone at +31 30 232 08 99 on weekdays from 10:00 to 16:00.
Slott's customer contact channels support multiple languages. Phone operators can assist in Dutch, English, German, and French. Written communication (email and postal) can be handled in these languages, as well as in Spanish and Italian, though responses in the latter two may take slightly longer due to limited staffing. For hearing‑impaired customers, a text‑based contact option is offered via email or the website's contact form; there is no dedicated TTY line. The walk‑in office is wheelchair accessible, and staff can arrange a sign language interpreter with 48 hours' notice. All contact details are subject to change during national holidays; the current hours are always displayed on the official website's contact page.
Slott does not maintain a 24/7 emergency line. For urgent travel issues occurring outside of regular business hours (such as lost tickets or missed connections while abroad), the website advises contacting the respective transport operator directly (e.g., NS, Thalys, or Eurostar). In extreme cases, travellers can leave a voicemail message at +31 30 232 08 08, which is checked the next business morning. There is no guarantee that out‑of‑hours messages will receive a same‑day reply. Slott recommends always downloading digital copies of tickets and storing the relevant operator's contact number before departure. For insurance‑related emergencies during a trip booked through Slott, call the insurance partner's hotline printed on your travel documents.
Business partners, travel agencies, and suppliers should contact Slott's commercial department through a separate email address: [email protected]. This mailbox is for proposals, contractual matters, and technical integration requests. The commercial team can also be reached by phone at +31 30 232 08 80 (Monday–Friday, 09:00–17:00). For media and press inquiries, contact [email protected]. All other contact channels are reserved for end‑customer support. Partner inquiries sent to the general info address may experience delays in forwarding.
