Customer Code = Cargo ID
In international shipping, a customer code is not just a simple mark. It works like a cargo ID inside the warehouse. 客户代码不是随便写的，它等于货物代码，也是仓库区分不同客户货物的重要识别方式。
When many cartons, wooden crates, pallets, Taobao parcels, 1688 goods, and supplier shipments arrive at the warehouse every day, customer code helps the team know which cargo belongs to which customer.
Actually, many cargo problems do not happen during sea freight or air freight. They happen at the beginning, when cargo enters the warehouse without a clear customer code.
Why Customer Code Matters in Shipping
A clear customer code helps the warehouse identify, sort, consolidate, load, and track cargo faster. Without it, cargo can be mixed with other customers’ goods, especially when cartons look similar.
客户代码的作用很简单：区分货物、减少混装、提高仓库分拣速度，让整票货物更安全、更准确地进入运输流程。
Identify
Quickly identify which customer the cargo belongs to.
Sort
Help warehouse staff sort goods into the correct shipping batch.
Avoid Mixing
Reduce the risk of mixing with other customers’ cargo.
Ship Safely
Make cargo handling faster, safer, and easier to track.

客户代码 = 货物在仓库里的身份证。
Customer Code FAQ
1. What is a customer code in international shipping?
A customer code is a unique mark used to identify a customer’s cargo in the warehouse. It can be written or printed on cartons, wooden crates, pallets, and packages.
中文说明：客户代码就是用来区分客户货物的代码。仓库通过这个代码判断这箱货是谁的、应该归到哪一票货里面。
2. Why do we say customer code equals cargo ID?
Because the customer code is the most direct way to identify cargo ownership. In a busy logistics warehouse, cartons from different customers may look very similar. The code tells the warehouse which cargo belongs to which customer.
简单说，客户代码就是货物的身份证。没有这个身份证，仓库就很难快速判断货物归属。
3. What happens if the carton has no customer code?
If a carton has no customer code, the warehouse may need extra time to check supplier information, order details, carton photos, or delivery records. In some cases, the cargo may be difficult to identify.
如果纸箱没有客户代码，就容易出现入仓慢、查货难、分拣慢，严重时还可能混到其他客户货物里面。
4. Can cargo be mixed with other goods without customer code?
Yes, the risk becomes higher. When many customers buy similar products, such as lighting, furniture parts, clothing, shoes, electronics, or Taobao goods, cartons may look almost the same from the outside.
所以客户代码越清楚，货物越不容易混装。尤其是多个供应商同时发货时，客户代码非常重要。
5. Should every carton have the customer code?
Yes. Every carton, wooden crate, pallet, or package should have the correct customer code. Do not only write it on one carton if the shipment has many packages.
中文说明：每一件货都要写客户代码，不是只写其中一箱。因为仓库是按件收货、按件分拣的。
6. Where should the customer code be written?
The customer code should be written clearly on the outside of the carton or package. It is better to put it on a visible side, not hidden under tape, packing film, or shipping labels.
建议写在纸箱外面明显位置，最好用大字或者贴标签，不要被胶带、缠绕膜、快递单挡住。
7. Can the supplier write the customer name instead of code?
It is better to use the official customer code. Customer names may be similar, incomplete, or written in different formats. A customer code is more standardized and easier for warehouse operation.
客户名字可能重复，也可能写错。客户代码更统一，更适合仓库快速识别。
8. Why is customer code important for Taobao and 1688 orders?
Taobao and 1688 orders often come from many different suppliers. If each supplier sends goods separately without a customer code, the warehouse may not know which buyer the parcel belongs to.
淘宝、1688货物特别要注意唛头和客户代码。因为供应商多、包裹多、外箱相似，如果没有统一代码，很容易乱。
9. Does customer code help speed up shipping?
Yes. A correct customer code can help warehouse staff receive, register, sort, consolidate, and ship the cargo faster. It reduces communication time and checking work.
客户代码写对了，仓库收货更快，分拣更快，合箱更快，后面安排运输也会更顺。
10. What is the best way to avoid cargo mixing?
The best way is to ask every supplier to write the same customer code clearly on every carton before shipping to the warehouse. For pallets or wooden crates, the code should also be visible.
最简单的做法：发货前告诉供应商，每一箱外面都写统一客户代码。不要一个供应商写名字，另一个供应商写电话，第三个供应商什么都不写。
Before your supplier sends goods to the warehouse, please confirm the customer code first. If the cargo arrives without customer code, warehouse identification may become slower and the risk of cargo mixing may increase.
供应商发货前，一定要确认客户代码。客户代码写清楚，货物就不容易走错路。
Correct vs Incorrect Customer Code Marking
| Situation | Result | Recommendation |
|---|---|---|
| Every carton has clear customer code | Fast identification and lower mixing risk | Best practice |
| Only one carton has customer code | Other cartons may be difficult to identify | Write code on every package |
| Supplier only writes customer name | Name may be incomplete or repeated | Use official customer code |
| No code on carton | High risk of slow receiving, wrong sorting, or cargo mixing | Confirm code before shipping |
How to Tell Your Supplier
You can send this message to your supplier before they ship the goods:
请在每个纸箱外面写清楚我的客户代码，再送到仓库。
For wooden crates, pallets, or large cargo, the code should also be attached outside the package in a visible position.
