Taxi passengers in Istanbul can now submit complaints, report lost items and share feedback through a new WhatsApp-based service launched by the Istanbul Taxi Drivers Chamber (ITEO) as part of broader efforts to improve service quality and customer satisfaction.

The initiative, called the "Yellow Line" (Sarı Hat), was announced by ITEO President Ismet Dalcı during a press conference at the organization's headquarters in the Kağıthane district of Istanbul.

Dalcı said the chamber has begun implementing reforms aimed at modernizing the city's taxi sector after taking office four months ago. "We promised not to apply temporary fixes but to completely transform the system," Dalcı said.

As part of the new program, QR code stickers linked to a dedicated WhatsApp number have been installed inside all commercial taxis across Istanbul. Passengers can use the service to report complaints, provide suggestions, recover lost belongings or submit positive feedback.

According to Dalcı, the chamber aims to respond to customer inquiries within five minutes.
