Yes, you can buy a ticket for multiple fellow travelers on one smartphone or mobile phone. 

You activate tickets via your personal De Lijn account. The account holder must stay with the group. During inspection, they must be able to show their identity card to the inspector.

Attention

Per purchase, you can order a maximum of:

• ten single tickets
• ten (3-)day tickets (child)
• five 10-ride cards
• two 50-ride cards
• one group ticket at a time and a maximum of 5 group tickets in your wallet
• 5 P+R Antwerp combi tickets
• 5 discount tickets for cities and municipalities

These are also the maximum number of tickets that you can still activate per account. Do you want to activate more at the same time? Then first activate the tickets you have purchased and immediately buy new ones afterwards.
