SSCC numbers

7 to 10 digits, from your GS1 membership certificate.

0614141 is GS1's example prefix. SSCCs made with it belong to no one; enter your own prefix before you print labels for a shipment.

9 digits with this prefix; we pad it with zeros.

Addresses

This is example data. Ship from, Ship to, Postal code, Carrier, Bill of lading, PO number, Item GTIN, Quantity. Replace it with your shipment before you print.

Leave blank to leave the postal barcode off.

What Goes on a GS1-128 Carton Label

Most retailer routing guides follow the GS1 logistic label layout: text zones at the top, barcodes at the bottom, and the SSCC barcode last. Our labels use these zones:

ZoneWhat it holds
Ship from / ship toNames and addresses, ship-to in larger type.
CarrierShip-to postal code as a GS1-128 barcode with AI (420), carrier name, PRO and bill of lading numbers.
CustomerPO number, store or mark-for, carton x of y, and the item GTIN and quantity for single-item cartons.
SSCCThe SSCC as GS1-128 with AI (00), 0.495 mm X-dimension, 31.75 mm bars and 10X quiet zones, with the number printed underneath.

The barcode sizes come from the logistic label table in the GS1 General Specifications (section 5.12.3.5), and the SSCC structure from section 3.3.1. Retailers add their own rules on top, so check your partner's routing guide; the GS1 US barcode guide is a good starting point.

Labels and the ASN Must Match

Every SSCC on a label has to appear in the 856 sent before the truck arrives, in the MAN*GM segment of its pack loop. The receiving dock scans the label and looks the SSCC up in the ASN, so a label missing from the ASN, or an SSCC with a wrong check digit, leaves the carton unmatched. Check a file in the EDI Inspector, which validates every SSCC check digit, and check single numbers with the check digit calculator. Cases also need their own GTIN-14 barcode, which the ITF-14 generator draws.

GTINs, SSCCs and GLNs must be built from a GS1 Company Prefix licensed to your company by your local GS1 member organisation, such as GS1 US or GS1 UK. Our examples use 0614141, the prefix GS1 uses in its own documentation. OrderSync builds these tools independently of GS1.

Frequently Asked Questions

What is an SSCC?

An SSCC (Serial Shipping Container Code) is the 18-digit number that identifies one carton or pallet in a shipment. It is printed on the shipping label as a GS1-128 barcode with application identifier (00) and sent in the 856 advance ship notice in the MAN*GM segment, so the receiving dock can scan the carton and match it to the ASN.

How is an SSCC built?

Extension digit (0 to 9, your choice) + your GS1 Company Prefix + a serial reference you assign + a check digit. The serial fills the remaining digits, so a 7-digit prefix leaves 9 digits for the serial. For example extension 0, prefix 0614141 and serial 1000 give 006141410000010004.

Is a UCC-128 label the same as a GS1-128 label?

Yes. UCC-128 is the old name, from when the Uniform Code Council ran the standard in the US. Retailer guides still say UCC-128, SSCC-18 label or carton label for the same GS1-128 shipping label.

What size should the SSCC barcode be?

For logistic labels GS1 specifies an X-dimension (narrow bar) of 0.495 mm to 0.940 mm, bars at least 31.75 mm (1.25 inches) high and a clear quiet zone of 10 times the X-dimension on each side. This generator prints at 0.495 mm and 31.75 mm, so the symbol fits a 4 x 6 inch or A6 label. Print the PDF at actual size.

Can I make labels from an 856 ASN?

Yes. Open the From an 856 ASN tab and paste the file. You get one label per MAN*GM SSCC, with the ship-from and ship-to, carrier, bill of lading and PRO from the shipment level and the PO and store from each order. SSCCs with a wrong check digit are listed instead of printed.

Do I need my own GS1 Company Prefix?

Yes, for real shipments. An SSCC must start with a GS1 Company Prefix licensed to your company, or retailers will reject it. The 0614141 prefix in the example is the one GS1 uses in its documentation; use it for testing only.

Is my shipment data uploaded?

No. The labels, barcodes and PDF are built in your browser. Addresses, PO numbers and pasted 856 files never leave your computer.
