What is Codabar?
Codabar (also called NW-7, USD-4, ABC Codabar, Monarch, or Code 2 of 7) is a self-checking 1D barcode designed in 1972. It encodes digits 0-9 plus the symbols - $ : / . + and uses one of four start/stop characters (A, B, C, D) to signal the symbol's intended use. No check digit required — the symbology is self-checking by design.
Where Codabar is used
- US blood banks (ISBT 128 predecessor): universal donor identifier.
- Libraries: 14-digit borrower / book IDs in US, Canada, EU.
- Photo finishing: order tracking on film envelopes (Kodak originally specified it).
- FedEx airbills: legacy use; replaced by Code 128 + Maxicode for current shipments.
- Healthcare: specimen tracking in some regions.
支持 26 种语言

Frequently Asked Questions
Why are there start/stop letters (A/B/C/D)?
Each pair signals a different intended use: A/A is the most common; D/D is used by libraries; B/B/C/C are used in specific industry profiles.
Is there a check digit?
Codabar is self-checking and traditionally has no check digit. Some industry profiles add Mod-16 or Mod-11 manually; we don't compute those.
Will iPhone Camera scan Codabar?
iOS Camera does not natively scan Codabar (as of iOS 17). Use a dedicated barcode app — or this site's scanner, which uses ZXing as fallback.
What's the difference vs Code 39?
Codabar is digits + 6 symbols (no letters); Code 39 is uppercase letters + digits + symbols. Codabar is denser for numeric-only data.
Can I generate Codabar in batch?
Yes — use batch CSV with type=codabar. Don't forget the start/stop letters.
What's the maximum length?
Up to 60 characters reliably.
Is Codabar still relevant in 2026?
Yes for legacy systems (libraries, blood banks). New deployments tend to choose Code 128 or QR.
