What Is an SSCC-18 Code?
An SSCC-18 is an 18-digit number used to label a logistics unit such as a pallet, a big carton, or a shipping container. The letters stand for Serial Shipping Container Code, and the number 18 means it has 18 digits in total. Big shops like Walmart, Amazon, Tesco, and Target ask suppliers to put an SSCC-18 on every pallet so they can scan it at the dock and know what is inside. Think of it as a name tag for a box. When the warehouse barcode generator scans that name tag, the supply chain system knows exactly which pallet just arrived. The SSCC-18 generator on this page makes those name tags for you, free and unlimited.

How SSCC-18 Codes Are Built: A Simple Explanation
An SSCC-18 code is 18 digits long, and every part has a job. Here is how the digits break down:
- 1-digit extension (digit 1): a number from 0 to 9. Usually 0, but you can use 1 to 9 to split batches.
- 7-digit GS1 Company Prefix (digits 2 to 8): the unique ID GS1 gives your company.
- 9-digit serial number (digits 9 to 17): a number you pick, like 000000001, 000000002, and so on.
- 1-digit mod-10 check digit (digit 18): a safety digit calculated from the other 17 so scanners can catch typos.
Add them up: 1 + 7 + 9 + 1 = 18 digits. That is your SSCC-18. When you print it as a barcode, the GS1 system also adds the Application Identifier (00) in front, so humans can read it as (00) 0 1234567 000000001 3. The SSCC-18 check digit calculator in our tool does the mod-10 math for you, so the last digit is always correct.
Step-by-Step: Using the SSCC-18 Generator
Making a batch of SSCC-18 codes takes less than a minute. Follow these four steps:
- Enter your GS1 Company Prefix. This is the 7-digit number GS1 licensed to your company. Type it in the prefix box.
- Pick a starting serial number. Use 000000001 for your first pallet, 000000101 for batch 2, and so on. Nine digits, padded with zeros.
- Choose how many to generate. You can make 1 code or up to 1,000 codes in one batch. The tool will count up from your starting serial.
- Copy or download the codes. Use the Copy button for quick paste, or download CSV / TXT for your warehouse management system.
That is it. No install, no signup, no rate limit. The serial shipping container code generator runs in your browser, so you can even use it offline once the page is loaded.
Real-World Examples of SSCC-18 in Use
Here are three real ways companies use SSCC-18 codes every day:
- Pallet label for a retail shipment: a supplier puts
0 1234567 000000001 3on a pallet of toys. The retailer scans it and links it to the ASN (Advance Shipping Notice) so they know which purchase order arrived. - Warehouse receiving: a forklift driver scans the SSCC-18 on a pallet at the dock door. The system adds it to inventory and finds the right storage bin automatically.
- Cross-dock operations: a parcel hub scans SSCC-18 codes on incoming pallets and instantly sorts them onto the right outbound truck, with no manual lookup.
In every case, the SSCC-18 is the single source of truth. The pallet barcode label tells the system what the pallet is, where it came from, and where it is going.
Who Uses an SSCC-18 Generator? Industries and Roles
An SSCC-18 generator is used across many industries. Here are the top five:
- Logistics & Freight: freight forwarders and 3PLs print SSCC-18 codes on every pallet moving through their network.
- Warehousing: warehouse managers use SSCC-18 to track inbound and outbound pallets.
- Retail Distribution: big retailers require SSCC-18 on supplier pallets to speed up receiving.
- Manufacturing: factories tag finished-goods pallets with SSCC-18 before shipping to distribution centers.
- Customs & Trade: customs brokers use SSCC-18 to identify cartons in mixed-load containers.
If your job touches a pallet, a carton, or a shipping container, you will probably meet an SSCC-18 code sooner or later. Our warehouse barcode label creator is built to make that meeting easier.
SSCC-18 Glossary: Key Terms Explained
Here is a quick glossary of the words you will see when working with SSCC-18 codes:
- SSCC-18
- Serial Shipping Container Code, an 18-digit GS1 number used to identify one logistics unit (a pallet, carton, or container).
- GS1 Company Prefix
- The 6 to 12 digit number GS1 licenses to your company. It makes your SSCC-18 codes globally unique.
- Extension Digit
- The first digit of an SSCC-18 (0 to 9). It gives you extra capacity to split batches by line, plant, or lane.
- Serial Number
- The 9-digit sequence (after the prefix) that you choose. Each pallet gets a unique serial so no two SSCC-18 codes are ever the same.
- Mod-10 Check Digit
- The last digit of an SSCC-18. It is calculated with the GS1 mod-10 algorithm so scanners can catch a mistyped digit.
- Logistics Unit
- Any unit made for transport and storage — a pallet, a carton, or a container. The SSCC-18 is the unit's name tag.
Tips for Getting the Best Results
A few small habits will save you big headaches when you generate SSCC-18 codes:
- Keep serial numbers sequential. Start at 000000001 and count up. It is much easier to find gaps later.
- Never reuse SSCCs. Once a pallet has been assigned an SSCC-18, that number is retired — even if the pallet is destroyed.
- Label each pallet uniquely. One SSCC-18 = one pallet. Mixing pallets under one code breaks tracking.
- Validate before printing. Use a barcode validator or the mod-10 check digit calculator to confirm before you print 1,000 labels.
- Store your prefix securely. Your GS1 Company Prefix is a licensed asset. Keep it somewhere safe so only approved staff can use it.
Common Mistakes to Avoid
Even smart teams make these four mistakes. Watch out for them:
- Using the wrong company prefix. If you have more than one GS1 prefix, double-check you picked the right one before generating.
- Reusing serial numbers. If pallet 000000001 was scrapped, do not give 000000001 to a new pallet. Pick the next free number.
- Forgetting the check digit. An SSCC-18 with the wrong last digit will be rejected by every modern scanner. Our SSCC-18 check digit calculator does it for you.
- Mixing up the extension digit. If you use extension 0 for domestic pallets and 1 for export, do not flip them by mistake. Write it down.
SSCC-18 Generator vs Other Methods
You have a few choices when it comes to making SSCC-18 codes. Paid GS1 software is powerful but costs hundreds or thousands of dollars a year and usually needs an install or a login. Manual Excel formulas can work, but you have to write the mod-10 math yourself, and one typo in the formula can ruin a whole batch. Pre-printed label services are convenient, but you pay per label and you cannot change the serial range on the fly.
Our free SSCC-18 generator sits in the middle. It runs in any browser, has no signup, and uses the real GS1 mod-10 algorithm so the codes are always valid. You can generate a batch of 1,000 codes, download CSV or TXT, and paste them straight into your warehouse management system. It is the simplest way to make a logistics unit identifier without buying software or risking a typo in a spreadsheet.
