UnionPay (银联)

UnionPay is China's domestic card scheme. It sits at the card-scheme layer beneath the two consumer wallets most foreign merchants encounter in mainland China — Alipay and WeChat Pay. The two wallets are acceptance agreements between a merchant and a wallet operator; the card scheme is the network layer beneath them, routing card transactions between an issuing bank and an acquiring institution.

A global company entering China will typically encounter UnionPay in one of two ways. First, a mainland customer may attempt to pay with a UnionPay-issued bank card — the cardholder side of the network. Second, a merchant evaluating payment acceptance may wonder whether UnionPay card acceptance is the same product as Alipay or WeChat Pay wallet acceptance. It is not. The wallets and the card scheme are separate acceptance surfaces on the same entity and filing foundation.

UnionPay International's English-language page states: "UnionPay cards can be smoothly used at 183 countries and regions worldwide." The same sentence renders on the UnionPay International English homepage.

What UnionPay International's English page states

UnionPay International's English-language online-payment product page renders the following content server-side, without requiring JavaScript.

Product heading. The page identifies itself as "Online Payment_UnionPay International."

Cardholder acceptance. The lead sentence states: "UnionPay cards can be smoothly used at 183 countries and regions worldwide." The page also renders a country picker organized by region (Asia, Europe, America, Oceania, Africa). The country names render server-side but include typographical errors (e.g., "Burkins Faso," "South SuDan"). We do not republish the country list or count countries ourselves. The 183 figure is the page's own claim.

Online-payment product family. The page lists four online-payment methods as navigation labels: 3DS, ExpressPay In-APP, Click to Pay, and PaybyLink. These labels render as English text. No feature descriptions, technical specifications, or integration documentation render server-side on the page.

No merchant-onboarding, acquiring, fee, eligibility, or corporate-profile content renders anywhere on the page.

What this page deliberately does not cover

This page is definitional and cardholder-side. It explains what UnionPay is and what the official English-language page states. It does not cover:

Merchant-side integration or acquiring paths. How a foreign merchant onboards to accept UnionPay cards, what acquiring institutions are available, and what the technical integration looks like are not documented in any English-language primary source we could verify. Two /en/aboutUs/ candidates returned HTTP 403 on 2026-10-03; no corporate-profile or merchant-onboarding facts were banked.
Fees, MDR, or pricing. No fee schedule renders on the English-language pages accessed.
Eligibility for foreign merchants. Whether a company without a mainland entity can accept UnionPay cards, and through which path, is not answered by the sources banked for this page.
Corporate structure or founding history. The /en/aboutUs/ pages returned HTTP 403. No ownership, founding, or organizational facts are banked.
UnionPay vs UnionPay International organizational split. Whether and how the domestic and international arms are separate entities is not addressed in the English-language sources accessed.
Market share, rankings, or transaction volume. No verifiable superlatives ("second-largest card network," etc.) are banked.
Chinese-name (银联) usage rules or brand guidelines. Not documented in the English-language sources accessed.

No citable English-language primary source covers these topics at a precision level we would publish here. If an English-language primary emerges, we will update this page and note the change.

How UnionPay relates to the payments stack a foreign merchant assembles

A global company entering China typically builds a payment stack with three layers. Understanding where UnionPay sits prevents a common planning error.

Layer 1 — Entity and filing foundation. The same filed entity (typically a WFOE) that holds the ICP filing typically holds both wallet acceptance agreements. Every acceptance surface discussed on this page sits on that foundation.

Layer 2 — Wallet acceptance (Alipay and WeChat Pay). Alipay and WeChat Pay are two separate merchant-acceptance agreements, each with its own onboarding path, merchant ID, and integration. The full decision frame — which wallet, which path, when both — is in our Alipay vs WeChat Pay term page and the WeChat Pay for Foreign Companies article.

Layer 3 — Card-scheme acceptance (UnionPay). UnionPay is the card network beneath the wallets. Accepting UnionPay cards is a separate acceptance surface from accepting either wallet — wallet acceptance is not card acceptance. How card acceptance is established, and through whom, is not documented in the English-language sources banked for this page; see the scope guard above.

Cross-border settlement is a property of the wallet merchant account, not the card scheme. WeChat Pay's cross-border settlement lists 26 settlement currencies, T+1 settlement, and an 800 USD minimum, with the settlement currency chosen once at merchant-ID registration — numbers the settlement page itself flags as listed, not confirmed-current terms. UnionPay card settlement for foreign merchants follows a different path — one that the sources banked for this page do not document in English.

H5 Pay — the mobile-web WeChat Pay flow — is also a separate surface. It processes WeChat Pay only; it is not an offshore payment gateway that also handles non-WeChat payment methods. Card acceptance via the card-scheme layer would be a separate surface from H5 Pay.

The practical question for a foreign merchant is not whether UnionPay matters in the abstract. It is whether your mainland audience includes UnionPay cardholders who expect to pay by card (as distinct from by wallet), and whether your acquiring setup supports card acceptance alongside wallet acceptance. The two are separate decisions.

Frequently asked questions

Is UnionPay the same thing as Alipay or WeChat Pay?

No. UnionPay is a card scheme — a network that routes card transactions between an issuing bank and an acquiring institution. Alipay and WeChat Pay are consumer wallets — each a separate acceptance agreement between a merchant and a wallet operator, with its own onboarding path, merchant ID, and integration. Wallet acceptance and card acceptance are separate surfaces; accepting a wallet is not the same as accepting UnionPay cards.

Where is UnionPay accepted?

Per UnionPay International's English-language product page: "UnionPay cards can be smoothly used at 183 countries and regions worldwide." The same sentence renders on the UnionPay International English homepage. We do not independently verify or count the countries; 183 is the page's own claim.

What online payment methods does UnionPay offer?

UnionPay International's English-language online-payment page lists four methods as navigation labels: 3DS, ExpressPay In-APP, Click to Pay, and PaybyLink. No feature descriptions or technical specifications render server-side; these are product-family names, not integration documentation.

Does accepting WeChat Pay mean we also accept UnionPay cards?

No. WeChat Pay wallet acceptance and UnionPay card acceptance are separate surfaces — holding the wallet agreement does not by itself mean accepting UnionPay cards. Whether and how a foreign merchant adds card acceptance is not documented in the English-language sources banked for this page.

Can a foreign merchant onboard to accept UnionPay cards?

This page cannot answer that question. No English-language primary source accessible to us documents merchant-onboarding paths, eligibility requirements, or acquiring relationships for foreign merchants. Two /en/aboutUs/ candidates returned HTTP 403 on 2026-10-03. Confirm directly with UnionPay International or a mainland acquiring institution.

Sources

Sources: The UnionPay statements on this page come from UnionPay International's English-language website — the online-payment product page (unionpayintl.com/en/servicesProducts/products/innovativeProducts/onlinePayment/index.shtml) and the English homepage (unionpayintl.com/en), both accessed 2026-10-03. The quoted lines — the 183-countries-and-regions sentence, the Online Payment page heading, and the four online-payment method labels (3DS, ExpressPay In-APP, Click to Pay, PaybyLink) — are locked to those pages; the 183 figure is UnionPay International's own claim, not an independently verified count. On-site facts — the two-wallets-as-separate-acceptance-agreements frame, the entity-and-filing foundation beneath both wallets, the H5 Pay boundary, and WeChat Pay's listed settlement terms — trace to the already-banked glossary pages named inline. Merchant-side onboarding, acquiring, fees, eligibility for foreign merchants, and corporate structure are deliberately not printed: the English-language /en/aboutUs/ pages returned HTTP 403 when accessed on 2026-10-03, and no banked primary supports them (see the scope note above).
