What is the Serial Number Generator?
Many barcode jobs start with a sequence of numbers rather than a list: asset tags AST-0001 to AST-0250, carton codes, ticket numbers, pallet IDs or batch labels. This generator builds that list for you - set a prefix and suffix, a starting value, an increment and how many codes you need, with optional zero-padding so every code sorts and scans consistently. Copy the result straight into any barcode generator on this site and print the whole batch.
Common Uses for the Serial Number Generator
- Asset tag runs like IT-2026-0001 through IT-2026-0400
- Sequential carton or pallet codes for a shipment
- Ticket, coupon and voucher number ranges
- Serialised product labels where each unit gets the next number
Choosing a format for serialised labels
Keep serial data alphanumeric-but-simple: uppercase letters, digits and dashes scan reliably in Code 128. Avoid lowercase letters and unusual symbols, and keep the whole string under about 20 characters so the barcode stays compact enough for your label. Pure numeric sequences can also be encoded in Interleaved 2 of 5 or ITF-14 for cartons, which are denser than Code 128 for digits.
From serial numbers to a printed barcode sheet
The typical workflow takes under a minute: generate the range here with your prefix and padding, copy the list, open the Code 128 generator, paste, and press Generate - every line becomes a scannable barcode on one printable sheet. Use the Print Sheet button to output a clean grid of labels, or copy individual codes into your own label artwork. Because everything runs in your browser, the numbers never leave your device.
Sequential numbers vs random serials
Sequential numbers are right for internal labels - assets, bins, work orders - where the number itself carries no meaning beyond being unique. Random or check-digit-protected serials are better when the code must resist guessing, such as gift cards or warranty registration. For retail products, do not use this generator at all: retail GTINs must come from GS1 or an authorised reseller.
