1. How to Identify: The 4-Digit Code
In Taiwan, you can distinguish the type of bus by its route number:
- City Bus (市區公車): Usually 1 to 3 digits (e.g., Bus 307). These stay within one city/county.
- Highway/Intercity Bus (國道/公路客運): Usually 4 digits (e.g., 1815, 9006). These travel via highways to cross city/county borders.
The 'Commuter' Culture
Don't be surprised to see long queues for these 4-digit buses during rush hour. Many locals live in neighboring cities (like Keelung or Yilan) but work in Taipei. They take these highway buses daily just like taking a subway. For example, Bus 1550 whisks people from Keelung directly to Taipei in 30-40 minutes.
2. Bus Transfer Stations (轉運站)
Unlike city buses that stop curbside, long-distance buses usually depart from large, indoor Bus Transfer Stations. These are often co-located with Train or MRT stations.
- Taipei: Taipei Bus Station (Q Square) and Taipei City Hall Bus Station.
- Taichung: Chaoma (朝馬) and Taichung Station Transfer Hub.
- Pingtung: Pingtung Transfer Station (next to the Train Station).

4. How to Ride: Do I need a ticket?
The most confusing part for travelers is knowing when to buy a ticket and when to just tap a card. Here is the rule of thumb:
🛑 Scenario A: 'Reserved Seat' (對號座)
Usually for: Long-distance (e.g., Taipei to Kaohsiung/Taichung) or trips via National Highway 5 (to Yilan).
- Rule: You MUST buy a ticket beforehand (Counter/Kiosk/App/7-11).
- Why: Standing is illegal on highways for these distances, and every passenger needs a guaranteed seat number.
- Process: Buy ticket ➝ Wait at gate ➝ Show ticket to driver ➝ Sit in your assigned seat.
🏃 Scenario B: 'Free Seating' (自由座 / 排隊上車)
Usually for: Commuter routes (e.g., Taipei to Keelung/Taoyuan) or shorter inter-city hops.
- Rule: First come, first served. No ticket needed if you have an EasyCard/iPASS.
- Process: Queue up ➝ Tap card upon boarding ➝ Find any empty seat ➝ Tap card again when exiting.
- Tip: Look at the bus LED sign or ask the driver: 'Swipe card?' (逼卡? Bī-Kǎ?).
