Alipay+ payment codes

Code types and rules

Alipay+ payment codes consist of three types: Alipay+ 19-digit code, CGCP code, and AlipayCN/AlipayHK code. Each type of payment code complies with specific rules.

Refer to the table below for Alipay+ payment code types and corresponding rules.

Type	Rules
Alipay+ 19-digit code	Starts with 28. The 3rd digit is fixed as 9, and the 6th digit from the end is fixed as 6. Example: `2893612204263667830`.
CGCP code	Starts with 25, 26, 27, 28, 29, or 30. Contains 1-digit agreement ID (by default equals 1) and 3-digit routing numbers that are used to recognize the MPP. For what valid routing numbers are and how they match MPPs, see Mapping between MPP and routing number. Example: `281010897274821897274821`, where the routing number is `010`.
AlipayCN/AlipayHK code	Length: 17 to 19 digits. Starts with 25, 26, 27, 28, 29, or 30. Example: `28024456785672301`.

Mapping between MPP and routing number

The following table describes the mapping between a Mobile Payment Provider (MPP), its CGCP code value, and the corresponding routing number, where

The Name of MPP column indicates which MPP the CGCP code value belongs to.
The CGCP code value column indicates the formats of the CGCP code values.
The Routing number column indicates the part of the CGCP code value that can be used to construct the regular expression for payment routing. For example, the routing number of MPP 1 is 001, so the corresponding regular expression is /^(2[5-9]|30)\d001\d*$/ . For more information about how to route the payment, see Routing logic.
