CDAC Prep Card

Generate a CDAC filling sheet before you open the official form.

This tool turns your hotel address, arrival details, and exit proof into a filling sheet you can copy into the official CDAC portal, plus a small fallback card for the airport or hotel desk. It does not submit anything, store anything, or replace the official form.

Needs prep

Use this when filling the official CDAC form. Copy values field-by-field; do not upload this to third-party CDAC services.

Airport fallback card

Show this if your hotel address needs manual confirmation at the airport, taxi stand, or hotel desk.

Please help me confirm this address.请帮我确认这个地址。

Readiness issues

  • Arrival port
  • Arrival flight or train
  • First-night hotel
  • Chinese address
  • Hotel phone
  • Planned cities
  • Exit ticket

High friction risk

  • High friction risk: the CDAC address, taxi address, and hotel check-in address may not match.
  • High friction risk: 240h transit travelers should keep confirmed onward proof ready.
  • Missing arrival flight or train details can slow down the form and airport fallback.
  • Hotel phone is useful if the address or late check-in needs manual confirmation.

Official portal

The card is free. Do not pay anyone.

Field guide

Arrival Flight/Train/Vessel Number — what to fill

Use your inbound travel document to identify the flight number, train number or vessel for your entry into mainland China. Look for the flight or service identifier, rather than a booking reference or ticket number. Keep the letters and digits shown on your document and follow the official form's instructions. If several identifiers appear, ask your carrier which applies to your arrival.

Where to find it

  • Flight: check the flight number on your boarding pass or airline itinerary for the segment entering mainland China.
  • Train: check the service number on your rail ticket or operator confirmation.
  • Vessel: check the vessel name on your ferry or cruise documents. Ask the operator if the form requests voyage details you cannot identify.

Common mix-ups

  • A booking reference identifies a reservation; it is different from the flight or service number.
  • For a connecting itinerary, identify the segment used to enter mainland China. A later domestic flight or your flight leaving China serves a different purpose.
  • Codeshare bookings can show more than one flight number. Check with the carrier if your documents and the form leave the choice unclear.
  • Keep the letters and digits on your travel document. Do not remove zeros or invent a number to make the field accept it.

Illustrated form walkthrough

These existing illustrations show the landing page and example form fields. The live portal's labels, sequence and available options may change. Use its current instructions when filling your own card.

CDAC landing page on s.nia.gov.cn — National Immigration Administration Government Service Platform header with Arrival Card Filling section showing Entry Declaration and Entry Declaration for Border Area Residents cards. Annotations point to the English language toggle and the Entry Declaration card.

Landing page · s.nia.gov.cn/ArrivalCardFillingPC

The official portal shows the National Immigration Administration logo (red emblem), the title "National Immigration Administration Government Service Platform", a 简体中文 / English language toggle in the top right, and two cards:

  • Entry Declaration — what most 240h travelers click.
  • Entry Declaration for Border Area Residents — only for citizens of DPRK, Mongolia, Pakistan, Nepal, Myanmar, Laos, and Vietnam holding border-resident certificates.

What scam sites do differently: different logo, different title, or any kind of fee prompt before you even start. The official site does not charge.

Before Step 1 — two click-throughs

  1. Instructions / agreement screen. Read the current instructions and exemptions before continuing. The announcement lists seven exemption categories; the current portal also includes courteous treatment through centralized document submission. See the exemption summaryand check the official instructions for your situation.
  2. Step 1 · Upload ID Document Page. Two fields: Type of ID Document (dropdown, default "Ordinary Passport"), and an Upload box — tap "+" to take a photo (mobile) or upload a file (desktop) of your passport's data page. NIA shows a small reference photo for correct framing. Click Next. OCR runs automatically, then the form loads with most of Step 2 pre-filled.
CDAC step 2 — Basic Information Filling page with Last Name, First Name, Gender, Date of Birth, Country of Citizenship, Type of ID Document, Passport Number, Entry Transportation Mode, Arrival Flight Number, City of Entry, Port of Entry

Step 2 of 5 · Basic Information Filling

OCR pre-fills most of this. Your job here is to verify, not retype. The fields on the left come from your passport (Last/First Name, Gender, DOB, Citizenship, Passport Number); the fields on the right are your flight (Entry Transportation Mode, Arrival Flight/Train/Vessel Number, City of Entry, Port of Entry).

Where mistakes happen: OCR commonly confuses O vs 0, I vs 1 vs l, and B vs 8 in the passport number. Open your passport next to the screen and check character-by-character. A wrong passport number here means your card won't match at immigration.

CDAC step 3 — Personal Information Filling with Chinese Name, Country of Birth, City of Birth, Contact Number, Email, valid visa question, Entry Policy Selection dropdown

Step 3 of 5 · Personal Information Filling

Most fields are self-explanatory. Two things that trip up 240h travelers:

  • Do you hold a valid visa or other entry permit? — Answer No for 240h visa-free transit. A "Yes" implies you have a regular tourist/business visa, which the system will then ask you to enter.
  • Entry Policy Selection — Pick "Visa-free Entry" (or the localized equivalent that lists 24/240-hour transit). This is the field that flags you as a transit traveler in NIA's system.

Chinese Name is optional unless you have one on official ID. Contact Number can be your home country number with country code — it just needs to reach you.

CDAC step 4 — Travel Information Filling with Purpose of Entry, Date of Entry, Destination Cities in China, Cities of Transit in China, Address in China, departure flight info

Step 4 of 5 · Travel Information Filling

The biggest section. 240h-specific notes:

  • Purpose of Entry — select the option matching your actual purpose and entry policy.
  • Destination Cities — prepare the cities in your itinerary and follow the form's prompts.
  • Address in China — prepare your actual hotel or host address and follow the form's language and field instructions. If the address is unclear, use the first-night address guide before submitting.
  • Confirmed Departure Itinerary: Yes, plus the exit flight number, date, and port. The form records your plans; it does not replace the confirmed onward ticket required for 240h transit.

Field deep-dive · Step 4

Confirmed Departure Itinerary on the China Arrival Card

For 240-hour transit travelers, the Confirmed Departure Itinerary question on Step 4 records your planned departure. Completing this field does not establish eligibility or replace your confirmed onward ticket. Check your route and supporting documents separately.

What "confirmed" means in NIA's eyes: a ticketed onward journey to a country or region different from the one you arrived from, with a fixed seat/cabin and a date that falls inside your 240-hour window. A reservation hold alone does not establish a confirmed ticket. Refundability does not itself tell you whether a ticket is confirmed. The departure must be on a real ticket the airline or rail operator can verify.

How to fill the form:

  • Confirmed Departure Itinerary — answer truthfully from your booking. If you do not have the confirmed onward ticket required for 240h transit, resolve that before relying on this entry policy.
  • Exit Transportation Mode — Aircraft, Train, or Vessel, matching how you'll leave.
  • Exit Flight/Train/Vessel Number + date + port — the same format rules as the arrival field (see Arrival Flight/Train/Vessel Number above). Check your travel document and ask the carrier if more than one identifier is shown.
  • Destination country/region — must be different from where you flew in from. A→China→A round trips do not qualify for 240h transit.

If automated systems can't see your onward ticket (separate bookings, different airline alliance, recently booked), bring backup evidence to the airline counter and to immigration:

  • Printed e-ticket PDF with passenger name, route, date, and operating carrier visible.
  • Booking confirmation email screenshot showing the airline's booking reference (PNR).
  • For rail: the China Railway 12306 e-ticket or operator booking with seat assigned.
  • For sea: the cruise line's pre-printed boarding pass or pier check-in voucher.

This summary covers the 240h case. For the full decision rules — including what visa holders and ordinary visa-free travelers without a booked exit should select — read the dedicated Confirmed Departure Itinerary guide. See also the denied-boarding guide for what happens when an airline check-in agent cannot verify your onward ticket — and how to recover.

Step 5 + final submit

Step 5 · Accompanying Person — anyone traveling on the same passport (usually only minor children). Leave blank if you're solo.

Final review & submit — sign the declaration, confirm, and the system generates a QR code / barcode receipt. Screenshot it immediately. Print if possible. Show it at immigration when asked.

Found an error? Follow the official service's current correction instructions. If the options are unclear, ask NIA 12367 or immigration staff at the port.

Common OCR mistakes to fix before submit

  • O vs 0 — passport letters in OCR often misread the letter O as zero.
  • I vs 1 vs l — capital I, digit 1, and lowercase L look identical.
  • B vs 8 — especially in machine-readable zones.
  • Name order — the system uses surname / given names. Western "first name last name" can flip incorrectly.
  • Birth date format — YYYY-MM-DD vs MM/DD/YYYY can swap day and month.

How to spot a scam CDAC site

NIA has issued multiple warnings about third-party sites that charge fees for the free arrival card service. They will charge you and may produce invalid QR codes that fail at immigration. NIA does not publish a specific blocklist — instead, watch for these patterns:

  • any domain ending in .com/.net/.org/.app (the only safe TLD is .gov.cn)
  • any site asking for a fee — the official service is 100% free
  • any site with 'china-arrival', 'china-entry-card', 'cn-immigration' style names that is not nia.gov.cn
  • any third-party that asks you to upload your passport image before redirecting to the official portal
  • any site that promises 'expedited processing' or 'guaranteed approval'
  • any site arrived at via paid Google ads claiming to be the official CDAC service

The single safe rule: the official URL ends in .nia.gov.cn. If the URL you're looking at is anything else — including .com, .net, .org, or.app — close the tab and go to s.nia.gov.cn directly. The official service is always free.

Exemptions, timing and corrections

What is CDAC China?

CDAC refers to China's Digital Arrival Card. NIA introduced online filling on November 20, 2025. Travelers who need an arrival card can fill it online before travel or at the port on arrival; paper arrival cards remain available. Some travelers are exempt.

Who is exempt from filling in an arrival card?

NIA's November 3, 2025 announcement lists seven categories: holders of a Chinese Foreign Permanent Resident ID Card; holders of a Mainland Travel Permit for Hong Kong and Macao Residents (Non-Chinese Citizens); group-visa holders or people eligible for group visa-free entry; direct transit within 24 hours without leaving the port's restricted area; people entering and exiting on the same cruise ship; people using fast lanes; and foreign crew of exit-entry transport vehicles. The live portal instructions checked on September 12, 2026 also list people eligible for courteous treatment through centralized submission of entry and exit documents, making eight categories there. Follow the current official instructions for your circumstances.

What goes in the Arrival Flight/Train/Vessel Number field on the CDAC?

Use your inbound travel document to identify the flight number, train number or vessel for your entry into mainland China. Look for the flight or service identifier, rather than a booking reference or ticket number. Keep the letters and digits shown on your document and follow the official form's instructions. If several identifiers appear, ask your carrier which applies to your arrival.

Is the China Digital Arrival Card free?

Yes. NIA's official online arrival card service is free. Use the official portal or NIA's official app and mini-program channels. NIA warns about counterfeit websites charging for this service.

When can I fill out the Digital Arrival Card?

NIA allows online filling before travel. Follow the arrival dates and instructions available in the current official form; the cited NIA announcements do not specify a universal 72-hour submission window.

What if I notice an error after submitting?

Open the official service and follow its current correction instructions. If the available options are unclear, ask NIA 12367 or immigration staff at the port. Check your passport and travel details before submitting; do not assume that a new submission is always the only way to correct a mistake.

What if I couldn't fill it before takeoff?

NIA says travelers unable to fill online in advance can do so on arrival using a designated QR code or devices at the port, or fill in a paper arrival card. Follow the instructions at your arrival port.

Online filling, arrival-port alternatives and exemption categories checked on 2026-09-12 against the NIA announcement and NIA's free-service notice. The portal instructions were also read on that date.
