# S/C No. 是什么？

## 问题

 刚入行，单据上S/C No.这栏该填什么？跟我们销售合同编号是一回事吗？填错了会不会影响客户付款和海关清关？ 

## 回答
                            
### 回答 1 — 最佳答案

S/C No。是Sales Contract Number（销售合同号）的缩写。从合规角度看，这个号码是海关审核贸易真实性的重要依据之一。您必须在商业发票、报关单以及随附合同上保持这个号码完全一致。如果涉及许可证管理商品，S/C No。还必须与许可证上的合同号对应，否则会被退单。特别注意：海关稽查时，这个号码是追踪整套交易文件的关键索引，建议您建立严格的编号规则并归档保存至少5年。

### 回答 2

S/C No。就是您整个物流链路的“主键”。操作层面，这个号码必须出现在商业发票、装箱单、提单、报关单所有主单证上，货代和报关行全靠它来关联文件。如果是EXW或FOB条款，客户可能提供他们自己的采购订单号作为S/C No。，您必须提前确认清楚到底用谁的编号，避免单据之间无法匹配。填错最直接的后果就是海关系统退单或查验，耽误船期。小技巧：可以把S/C No。打印在外箱唛头上，方便目的港快速识别。

S/C No。本质上就是您这笔订单的“身份证号”。商务沟通中，建议您在邮件主题、合同页眉、付款水单备注等所有环节都坚持使用这个号码，这会显得您极其专业。特别是在信用证结算时，S/C No。必须严格出现在所有议付单据上，银行审单时会逐字核对。如果客户要求修改合同号，您需要评估是否会影响已经提交的银行文件。一个实用话术：“为了确保顺利付款和清关，请后续沟通都引用S/C No。： XXX，谢谢配合！” 这样能有效避免客户随意更改编号导致的混乱。
