China Construction Bank (CCB) has two exchange-listed ordinary-share lines: Hong Kong H-shares, ticker 939, and Shanghai A-shares, ticker 601939. To buy either, you need a securities intermediary that accepts customers in your jurisdiction and supports the relevant exchange or an eligible Stock Connect route. The listings have different board-lot sizes and may involve different account, currency, settlement, and trading rules, so identify the exact share line before funding an account or placing an order.
This guide explains how to check access and place an order. It is procedural information, not a recommendation to buy CCB or an assessment of its value, finances, or suitability for you.
CCB stock at a glance
China Construction Bank is listed in two markets. The issuer’s General Shareholder Information identifies its H-shares on the Main Board of the Stock Exchange of Hong Kong Limited (SEHK) under ticker 939, and its A-shares on the Shanghai Stock Exchange (SSE) under ticker 601939. CCB says the H-shares were listed on 27 October 2005 and the A-shares on 25 September 2007. Its History page also records those listing dates and codes.

| Share line | Exchange and ticker | Issuer-stated board lot | Key access question |
|---|---|---|---|
| H-shares | SEHK Main Board, 939 | 1,000 shares | Does your intermediary support Hong Kong trading for your account and country? |
| A-shares | SSE, 601939 | 100 shares | Can you trade the security directly or through an eligible Stock Connect route, and what account and settlement terms apply? |
The board-lot figures are published by CCB. They identify the issuer’s stated standard lot size; they do not by themselves confirm that every intermediary accepts only whole lots, how it handles odd lots, or what its current order rules are. Check the dealing screen and account terms before submitting an order.
#1 Best Overall
Choose which CCB listing you want
The first decision is not whether to press “buy,” but which security and trading venue you mean. Search results or brokerage watchlists can display similar company names while referring to different listings. Match the ticker, exchange, and security description together rather than relying on the company name alone.
- For Hong Kong H-shares: look for China Construction Bank, ticker 939, with the venue shown as the SEHK Main Board or Hong Kong market.
- For Shanghai A-shares: look for China Construction Bank, ticker 601939, with the venue shown as the SSE or Shanghai market.
Do not assume that access to one line gives you access to the other. A brokerage account may support one market but not the other, and cross-border access can have its own eligibility conditions. Before you open or fund an account, make sure the actual order ticket offers the intended listing.
How an intermediary provides access
Most individual investors access an exchange through a brokerage or other securities intermediary. The intermediary’s service area, customer eligibility, supported exchanges, account setup, funding methods, and charges depend on that provider and the customer’s jurisdiction. There is no single provider requirement or universal fee schedule established for every country and account.

For ticker 939, ask the provider whether the account can place orders on the SEHK, what currency the account uses for the trade and settlement, and how it handles conversion if your available funds are in another currency. Confirm commissions and exchange or other charges in the provider’s current tariff, plus any account or custody fees that apply to your account. The specific charges and conversion terms are provider-dependent; do not estimate them from the share ticker or board lot alone.
Trading Shanghai A-shares
A customer outside mainland China may encounter cross-border access rather than an ordinary direct SSE order. One route described by China Construction Bank (Asia) is Northbound Stock Connect, through which overseas investors may trade eligible securities on the SSE or Shenzhen Stock Exchange (SZSE), subject to the program and provider’s terms. CCB (Asia)’s page is an example of one provider’s service, not a universal account specification or a guarantee that every investor can trade CCB through it.
Before relying on Stock Connect, check that ticker 601939 is currently eligible through the particular route and intermediary you plan to use. Eligibility can change, and the route’s trading calendar, available order types, quotas, holding restrictions, and settlement arrangements can affect whether an order can be submitted or completed.
Check costs, funding, and account requirements before depositing
There is no reliable single purchase cost to quote without a live share price, the account’s currency, the quantity, the provider’s charges, and any currency conversion. A simple planning calculation is:
Estimated cash needed = share quantity × your limit price + applicable transaction charges + any currency-conversion cost.
This is a budgeting framework, not a quote. The actual amount reserved, charged, or settled may depend on the provider’s order and settlement rules. Obtain the current charges from the intermediary before placing a trade; no current share price or universal fee schedule is published here.
Use these checks before transferring funds:
- Confirm that the intermediary accepts clients who reside in your country or region and that the intended market is enabled for your account.
- Check identity-verification and account-opening requirements directly with the provider.
- Find out which currency you must deposit or hold, how exchange-rate conversion is calculated, and whether conversion charges apply.
- Confirm the minimum order, permitted quantity increments, board-lot handling, and any odd-lot process in the actual account.
- Review commissions, exchange charges, taxes or levies if applicable, custody or account fees, and the timing of deductions in the provider’s current terms.
- For a Stock Connect order, confirm the route’s specific account and RMB funding requirements rather than assuming that the rules for a Hong Kong order also apply.
For example, CCB (Asia) says its own Online Banking securities service requires the customer to be an online banking customer with a securities trading account. Its Northbound service page also specifies an RMB settlement account requirement for that service. These are examples of one provider’s conditions, not requirements that can be applied to every intermediary.
Step-by-step: placing a CCB share order
- Confirm your market access. Ask the intermediary whether the account can trade SEHK ticker 939 or SSE ticker 601939, as applicable. If using Stock Connect, verify the current eligibility of the exact security and the route’s requirements before moving money.
- Complete the account setup. Follow the provider’s identity, account, and market-access steps. Do not infer that an existing general investment account is enabled for Hong Kong, Shanghai, or Stock Connect trading; check the account’s permissions and status.
- Fund the account in the required way. Check the accepted funding currency, settlement currency, conversion method, and processing time. For the particular CCB (Asia) Northbound service described by the bank, settlement is in RMB; another provider may have different account mechanics.
- Open the security’s order ticket and verify its identity. Confirm the company name, ticker, and exchange together: 939 on the SEHK for H-shares, or 601939 on the SSE for A-shares. Stop if the venue or security description does not match your intended listing.
- Choose the order side, quantity, and permitted order type. Select Buy, enter the quantity, and review any lot or quantity increment shown by the provider. If trading through CCB (Asia)’s described Northbound service, its page specifies limit orders only; that is a provider-specific rule, not a claim about every route or broker.
- Set and review a limit price if using a limit order. A buy limit sets the highest price you are willing to pay per share, but it does not guarantee execution. The order may remain unfilled if the market does not offer shares at that price under the applicable trading rules.
- Check the complete order before submission. Re-read ticker, venue, Buy/Sell side, quantity, order type, limit price, account, and estimated cash or charges. A wrong listing code or market cannot be corrected by choosing the right company name elsewhere on the ticket.
- Submit, then check the order status. A submitted order is not necessarily an executed trade. Check whether it is pending, partially filled, rejected, or completed. If it is rejected, read the provider’s reason before changing quantity, price, account, or route.
- Review trade and account records. Once an order executes, check the execution details, fees, currency conversion, settlement entries, and resulting holding in the intermediary’s records. Follow the provider’s terms for any order changes, cancellations, or settlement questions.
What Stock Connect can change about an A-share order
Stock Connect is a channel with its own operating rules, not simply another label for direct Shanghai trading. CCB (Asia)’s Northbound page describes its own service for eligible SSE and SZSE securities and identifies several mechanics relevant to a customer using that service. The details below should not be generalized to a different intermediary; current terms can change.
Recommended Free Tools
| Mechanic described by CCB (Asia) | What a customer should check |
|---|---|
| Limit orders only for the described Northbound service | Whether the order screen permits only limits, and how long the order remains active under the provider’s rules. |
| No day trading in that service | Whether a newly bought position can be sold on the same day; do not plan an intraday round trip unless the applicable rules explicitly allow it. |
| Maximum order quantity of one million shares | Whether the limit still applies to the account and current service terms, and how quantity is entered for the security. |
| Stock settlement on trade day; cash settlement on trade day plus one | How the provider defines the relevant trading day, when shares appear as settled or available, and when cash is debited or credited. |
| RMB settlement | How the account obtains RMB, whether conversion is needed, and which conversion costs or timing apply. |
These figures and mechanics are the terms CCB (Asia) states for its listed service, not a current guarantee for every Northbound provider. The same page says customers need an RMB settlement account. Verify the latest provider rules and the exchange/program calendar for the account you will actually use.

Risks and restrictions to understand before trading
Buying a listed share exposes an investor to the share price and company-specific risks. Cross-border access can add route, currency, calendar, and operational constraints. The Stock Connect disclosures published by CCB (Asia) identify the following issues; they are not an exhaustive list of investment risks, nor do they predict what will happen to a particular order.
Currency exposure
If your base currency differs from the currency used to fund or settle a trade, exchange-rate movements can affect the amount you ultimately spend or receive in your own currency. A conversion charge or provider spread may also apply. Ask the intermediary how it handles currency conversion and where it displays the applicable rate; do not assume that the price shown in the order ticket is your final home-currency cost.
Different trading calendars and service availability
CCB (Asia)’s Stock Connect risk disclosure warns that the channel may not operate on every day a mainland market is open. The relevant market and route calendars can therefore affect when an order can be entered or traded. Check the specific trading calendar and provider notice rather than relying only on a local holiday calendar or the fact that an exchange is open.

Eligibility, quotas, and ownership limits
The set of securities available through Stock Connect may change, and quotas or foreign shareholding restrictions can constrain orders or holdings. The CCB (Asia) disclosure says restrictions can limit purchases or require holdings to be reduced. A security appearing in a watchlist does not establish that a new order will be accepted; verify its live eligibility and any applicable restrictions at the point of trading.
Best Value
Recalled securities and sell-only restrictions
The risk disclosure says a security recalled from eligibility may become restricted to sales through the channel. This could limit further purchases even when a holding remains in the account. Check notices from the intermediary and the route if an order is unexpectedly unavailable or the security’s status changes.
Order acceptance is not guaranteed
An intermediary can reject or restrict an order for reasons such as a mismatch with its account rules, route eligibility, trading calendar, quota, permitted order type, or quantity limits. An accepted order can also remain unfilled, especially when a limit price is not reached. Read any status or rejection message in context before resubmitting; changing the price or quantity without understanding the reason may not solve the problem.
How to verify a problem or unresolved detail
Start with the source best placed to answer the specific question. Use CCB’s General Shareholder Information for issuer-published share identification and lot-size information. Use the intermediary’s current terms and order screen for account permissions, charges, order handling, funding, settlement, and rejected orders. For Stock Connect, check both the intermediary’s live service information and current route eligibility and risk notices.
For company-specific shareholder questions, CCB’s Investor Relations page lists the issuer’s contact channels. The issuer can clarify its own shareholder information, but your intermediary is the relevant source for whether your account can place a trade and what it will charge or settle.
