Sequential Barcode Generator
Instantly create auto-numbered barcodes for asset tracking, tickets, and serial numbers. Just set your range, and let our engine build up to 50,000 labels perfectly sequenced.
How to auto-generate numbered barcodes
Skip manual data entry. Build custom sequences in three simple steps.
Set Your Prefix
Define static text that appears before your numbers. For example, if you are labeling company laptops, set your prefix to "IT-MAC-".
Define The Range
Choose your starting number and ending number (e.g., 1 to 500). You can also set the "Padding" so the numbers look clean and uniform (e.g., 001 instead of just 1).
Generate & Print
Click generate, and our engine will build the entire sequence. Download a high-resolution PDF roll that is perfectly formatted for your thermal barcode printer.
The ultimate tool for asset tracking and ticketing
Whether you are printing serial numbers for manufactured parts, tracking warehouse bins, or printing admission tickets, our sequential engine ensures zero duplicates and perfect formatting.
-
Custom Zero-Padding Keep your barcodes the same width by padding numbers with zeros. Easily generate formats like 00001, 00002, 00003.
-
Duplicate Quantity Controls Need two identical labels for every sequence number (e.g., one for the box, one for the product)? Just set the "Qty Each" setting to 2.
-
Universal Symbology Easily switch your sequenced numbers into Code 128, Code 39, or standard EAN-13 retail formats.
Frequently Asked Questions
What does the "Padding" setting do?
Padding forces your sequential numbers to always have a specific number of digits by adding zeros to the front. For example, if your start number is 1, and your padding is set to 4, the generator will output 0001, 0002, 0003. This ensures all your printed barcodes are exactly the same width.
Can I add text after the sequential number (a Suffix)?
Currently, our standard tool supports a text Prefix (text before the number). If you need complex setups including suffixes (like BOX-001-A, BOX-002-A), we recommend generating that list in Excel using the drag-down feature, and then uploading it to our Excel Barcode Generator.
How many sequential labels can I generate at once?
Our high-performance engine can generate up to 50,000 sequenced labels in a single batch. Premium users can download the entire sequence instantly as a ZIP file containing individual PNG images, or as a single, continuous PDF document ready for thermal printing.
