STAN 和 RRN 有什么区别?STAN vs RRN: What's the Difference?
两个都是"交易编号",新手最容易混。简单说:STAN 是当天、短期的流水号;RRN 是跨系统、长期的追踪号。
Both are "transaction numbers" and beginners mix them up. In short: STAN is a short-term, same-day trace number; RRN is a long-term, cross-system tracking reference.

| 全称Full name | 系统跟踪审计号System Trace Audit Number | 检索参考号Retrieval Reference Number |
| 长度Length | 6 位数字digits | 12 位chars |
| 谁生成Set by | 发起方(终端/收单)Originator (terminal/acquirer) | 收单方Acquirer |
| 唯一范围Uniqueness | 当天、单机构内唯一Unique within a day/host | 较长期、跨系统追踪Longer-lived, cross-system |
| 主要用途Main use | 冲正/应答匹配当笔Match reversal/response to this txn | 退款/查询/对账引用Refund/query/reconciliation reference |
一句话记住:STAN 像"今天的排队号"(当天有效、用来配对应答/冲正);RRN 像"快递单号"(长期用来跨系统找回这笔交易)。Remember: STAN is like "today's queue number" (valid for the day, matches responses/reversals); RRN is like a "tracking number" (used long-term to retrieve the transaction across systems).
