Quick answer

Open the issued ticket in the channel that sold it and review its change or refund options. The amount and deadline depend on the ticket and timing. A mainland domestic train and a cross-boundary Hong Kong journey may follow different arrangements, so do not apply a generic percentage table to every ticket.

Gather the right order

Keep the passenger’s document, train number, travel date, station names, original payment record and order number together. Check whether you are looking at an issued ticket, an unpaid reservation or a waitlist request. Cancelling one does not necessarily cancel the others.

If you booked through an agent such as Trip.com, start with that agent’s order. A rail refund and an agent’s service charge may be handled separately. Ask what will be returned before accepting the change.

Bought the wrong ticket on official 12306?

Registered 12306 users may qualify for a fee-free accidental-purchase refund for an eligible new ticket bought through the official website, app or Alipay mini-program using electronic payment or reward points. Complete the refund within 30 minutes of payment and at least four hours before the scheduled departure. The allowance is one order per purchasing account per calendar day.

The policy covers travel from February 2, 2026 on mainland domestic services and trains starting or ending at Hong Kong West Kowloon. It excludes rebooked, pre-ordered, waitlisted, group, multi-ride/periodic, Railway e-Pass and air-rail/waterway-rail tickets.

Open the order promptly and check the terms shown before confirming. Do not assume a third-party booking qualifies, or that starting a request holds the deadline. This is an existing 2026 policy, checked October 6, 2026 (China time, UTC+8); see question 17 under Endorsement and refund in the official 12306 English FAQ.

If your train is cancelled or delayed

For a cancelled mainland domestic train, China Railway allows a refund without a rail refund fee from the cancellation announcement until 30 days after the ticket's travel date. For an unused delayed train, request the refund before it actually departs from your ticket's departure station.

Tell the booking channel about connecting tickets before cancelling separately. Eligible connecting tickets bought before the disruption was announced can be refunded together without a rail refund fee. For a cancelled train, those connecting tickets must be handled before their departures. Separate requests follow ordinary refund rules.

A connecting itinerary means linked journey segments between your origin and destination; adjacent segments must connect at the same station or stations in the same city. It does not mean every later train in your holiday.

Ask 12306, a staffed railway counter or your original seller to check your tickets and any agent charges. Hong Kong cross-boundary services have separate conditions.

A practical decision sequence

  1. Read the current ticket status and the available actions.
  2. Search for an acceptable replacement, including its exact station and date.
  3. Compare changing the existing ticket with refunding and buying another.
  4. Review any fare difference, fee and payment request on the confirmation screen.
  5. Submit once, then verify the new ticket status and details.

Do not assume a replacement seat is held just because it appears in a search. Do not discard the old order information until the change is confirmed.

Open the correct order and review the terms before confirming any change or refund.

If online changes are unavailable

Contact the original booking channel or a staffed railway counter with the original travel document. Receipt rules depend on the journey. For eligible mainland domestic e-tickets, railway electronic invoices are issued after travel or after a refund/change; do not apply an old paper-receipt rule to these tickets. For Hong Kong cross-boundary tickets, MTR says a collected paper reimbursement receipt must be returned when changing or refunding the ticket and can restrict online handling. Tell support which kind of ticket and receipt you have.

When departure is near or you missed a train, seek assistance promptly. This guide does not promise that a particular late change is available. The offer shown for your ticket and the railway’s current rules control the outcome.

Follow the money

Keep the refund confirmation and payment reference. A confirmed refund request may take time to reach the original payment method. Ask the seller for its expected processing period and contact the issuer if the money is still missing after that period.

For a charge with an unclear order status, use pending-payment troubleshooting.
