Warehouse logistics coordinators and EDI specialists can eliminate shipping errors with our GS1 SSCC-18 generator/validator. Quickly construct Serial Shipping Container Codes by combining your unique company prefix with continuous serial numbers. The built-in Mod-10 algorithm automatically generates or verifies the crucial check digit, allowing you to seamlessly export clean, compliant tracking logs via CSV for your Advance Ship Notices (ASNs).
The Serial Shipping Container Code (SSCC) is a globally unique 18-digit identifier used to track individual logistics units, such as pallets or cases, as they move through the supply chain. It is commonly encoded in GS1-128 barcodes.
The Mod-10 algorithm applies alternating mathematical weights to the first 17 digits of the SSCC. The result determines a final 18th digit, which prevents data entry errors and ensures barcode scanners read the code accurately.
No, to ensure global uniqueness, you must obtain an official Company Prefix by licensing it directly from a regional GS1 member organization, such as GS1 US.
An ASN is an electronic data interchange (EDI 856) document sent to a retailer before a shipment arrives. The ASN links the unique SSCC on the pallet's barcode to the specific products contained inside, enabling rapid receiving.
