Free HIBC Code 128 Barcode Generator — Healthcare UDI Labels, Instant & Compliant

HIBC Code 128 is a healthcare-specific application of the Code 128 linear barcode symbology, defined by ANSI/HIBC 2.6 and managed by the Health Industry Business Communications Council (HIBCC). The key differences from standard Code 128 are: (1) every HIBC symbol must begin with a '+' character as the HIBC industry identifier; (2) the encoded data follows a prescribed structure — LIC + PCN + Unit of Measure for primary data; (3) a MOD 43 check character (not Code 128's standard Mod 103 check) is computed from all HIBC data and appended; and (4) the human-readable interpretation uses HIBC formatting conventions (slashed zeros, underscores for spaces). A standard Code 128 scanner can read the bars, but HIBC-aware systems additionally parse and validate the structured content.

A Labeler Identification Code (LIC) is a unique 4-character alphanumeric identifier issued by HIBCC to each manufacturer ('labeler') of healthcare products. The LIC is the first element of every HIBC Primary Data Structure and links the barcode to a specific company in the HIBCC registry. To obtain an LIC, you must submit an application to HIBCC (hibcc.org) and pay a one-time subscription fee. Once issued, your LIC is permanent and can be used across all your product lines at no additional per-barcode charge. You cannot legally use an HIBC barcode with an LIC that has not been assigned to your organization.

The MOD 43 check character is a mandatory error-detection element required in every HIBC barcode. It is calculated by assigning a numeric value (0–42) to each character in the complete data string — including the '+' flag, LIC, PCN, and all secondary data — summing those values, and computing the remainder when divided by 43. The resulting remainder maps back to an alphanumeric character that is appended to the barcode. This generator computes and appends the MOD 43 check character automatically. You never need to calculate it manually. Scanners verify the check character on every read and reject any barcode where the computed value does not match.

The HIBC Primary Data Structure is the mandatory component of every HIBC Supplier Labeling Standard barcode. Its format is: + [LIC] [PCN] [Unit of Measure] [Link Character] [MOD 43 Check]. The '+' is the fixed HIBC flag. The LIC is your 4-character HIBCC-assigned labeler code. The PCN is your product or catalog number — up to 18 uppercase alphanumeric characters. The Unit of Measure is a single digit (0–9) indicating the packaging level (e.g., 0 = each, 1 = each with secondary data). The Link Character is derived from the MOD 43 calculation and connects primary to secondary data. The final MOD 43 character provides error detection. Example: +A999BJC5D6E71 encodes LIC 'A999', PCN 'BJC5D6E7', Unit of Measure '1'.

The HIBC Secondary Data Structure is optional but required for FDA UDI compliance when the device has a production identifier (PI). It can encode: expiration date (in formats such as YYYYMMDD, YYJJJ Julian, or MMYYYY); lot or batch number (up to 18 alphanumeric characters); serial number (up to 18 alphanumeric characters); manufacture date; and quantity. The secondary structure begins with '+' and a Link Character derived from the primary barcode's check calculation, followed by production data, and ends with a new MOD 43 check character. When concatenated into a single Code 128 symbol, the '+' and Link Character are replaced by a '/' delimiter and only one MOD 43 check is used for the combined string.

The FDA does not mandate a specific barcode symbology or issuing agency — it accredits three agencies: HIBCC (which issues HIBC barcodes), GS1 (which issues GTINs used in GS1-128 and GS1 DataMatrix), and ICCBBA (for human-derived medical products). You may choose any of the three. However, once you choose HIBCC as your issuing agency and obtain an LIC, your UDI barcodes must follow the HIBC standard — HIBC Code 128 or HIBC Data Matrix are the most common formats. Approximately 15% of devices in the FDA GUDID database use HIBCC-issued identifiers, with the remaining ~85% using GS1.

ANSI/HIBC 2.6 requires that Code 128 and Code 39 symbols in their final printed configuration achieve a minimum quality grade of C/06/660 as measured per ISO/IEC 15416. The notation means: grade C (on a scale of A–F), aperture 0.006 inches (6 mils), and 660nm illumination wavelength. HIBCC recommends that labelers target grade B/06/660 or better at the time of printing to allow for label degradation during distribution and storage. Use a certified ISO/IEC 15416 barcode verifier — not just a barcode scanner — to measure print quality. A scanner confirms a barcode can be read in ideal conditions; a verifier grades it against the standard.

ANSI/HIBC 2.6 recommends an X-dimension (module width — the width of the narrowest bar or space) of 0.010 inches (0.25 mm) as the standard for healthcare labels. Higher-resolution printing environments may use a smaller X-dimension, but this increases scanner compatibility risk. The quiet zone — the mandatory blank space on each side of the barcode — must be a minimum of 10 times the X-dimension, or at least 0.10 inches (2.54 mm), as required by the underlying ISO/IEC 15417 standard for Code 128. This generator includes correct quiet zones automatically at the default module width and all custom widths.

Yes. To generate a concatenated HIBC symbol encoding both primary and secondary data in a single Code 128 barcode, enter your data using the HIBC concatenation format: [LIC][PCN][Unit of Measure]/[Secondary Data]. The '/' acts as the delimiter between primary and secondary segments in the concatenated format, replacing the secondary '+' flag and Link Character. The generator encodes the full concatenated string, prepends '+', and appends a single MOD 43 check character covering the entire data string. This is the recommended approach when label space is limited and both device identifier and production identifier must appear in one linear barcode.

Yes. All HIBC Code 128 encoding is performed entirely in your browser using client-side JavaScript. Your LIC, product catalog numbers, lot numbers, serial numbers, expiration dates, and any other sensitive healthcare identifiers are never transmitted to any server and never stored anywhere. Close the browser tab and all data is cleared from memory. This tool is safe to use with proprietary product data, pre-submission regulatory information, and any other sensitive identifiers.
