E-commerce listing: common differences in barcode requirements

Platforms do not have entirely consistent requirements for product codes. The following are common requirement directions; the platform's current rules shall prevail.

Platform typeCommon coding requirementsCommon supplementary requirements
Domestic comprehensive e-commerce (Tmall / JD)Product barcode starting with 69 (GTIN-13)Some categories require proof of code ownership
Domestic content e-commerce (Douyin / Kuaishou Shop)GTIN codes; some categories may apply for exemptionCategory qualifications and quality inspection reports
Cross-border platforms such as AmazonUPC / EAN（GTIN-12 / 13）Some brands can apply for a GTIN exemption, but most categories still require a formal code
Independent sites and self-built storesThere is no mandatory requirement, but using a GTIN is recommended for integration with price comparison and logistics systemsWarehousing and logistics integration specifications

Platform rules may be adjusted. Before listing, please refer to the platform's official documentation; we can help verify whether your products match the platform requirements.

Implementation Steps

STEP 01

Confirm sales platform and market

Domestic, cross-border, or both in parallel — this determines which number segment you need

STEP 02

Sort out product items

List the SKU inventory and specification differences (colors, sizes, and capacities each coded independently)

STEP 03

Apply for codes

Apply for the corresponding number segment by market and obtain the manufacturer identification code

STEP 04

Code assignment and printing

Assign a number to each SKU and deliver it to the packaging designer to place the barcode according to the specification

Common pitfalls

  • Multiple specifications sharing one code — Different colors/sizes must be coded independently, otherwise inventory and orders will be mismatched
  • Manually entered check digit errors — After printing, the machine cannot scan it, and the entire batch of packaging is scrapped.Verify first, then use
  • Barcode size too small or insufficient contrast — Checkout counters and logistics scanners fail to recognize it
  • Ignoring the platform's proof requirements for code ownership — Listing review gets stuck
  • Using self-invented numbers — Conflicts with existing codes, and the platform rules it invalid
If your product is already on sale but the barcode has issues, don't rush to change the code — changing the code means all packaging and platform data must be changed. First have a consultant assess the scope of impact.
