S25 Barcode Generator

What is an S25 Barcode?

Standard 2 of 5 (S25 or STF) is a simple, numeric-only barcode symbology that encodes digits using a pattern of wide and narrow bars. Developed for industrial applications, S25 provides a compact way to represent numeric data without requiring complex encoding schemes.

Key Features of S25 Barcode

✔ Numeric-Only Encoding – Supports digits 0-9
✔ Compact Design – Uses variable-width bars for efficient space usage
✔ No Checksum (Basic Version) – Simple implementation
✔ Industrial Applications – Widely used in warehouse sorting and photo processing

How S25 Barcode Works

The S25 format uses:

• Two wide bars and three narrow bars per character (hence “2 of 5”)

• No start/stop characters in its basic form

• Optional checksum versions for improved accuracy

Encoding Example

The number “1234” would be represented as alternating patterns of wide and narrow bars for each digit.

Applications of S25 Barcode

• Warehouse Sorting Systems – Package and pallet tracking

• Airline Ticket Numbering – Early baggage handling systems

• Photo Finishing – Film processing identification

• Industrial Manufacturing – Component tracking
