What Is an ISSN Barcode?
The International Standard Serial Number (ISSN) is an eight-digit numeric identifier assigned to serial publications — including academic journals, magazines, newspapers, newsletters, and annual reports — by the ISSN International Centre in Paris and its national network of ISSN centers. Standardized under ISO 3297, each ISSN uniquely identifies a specific publication title regardless of language or country of origin. An ISSN barcode encodes this identifier in a machine-readable linear format — typically rendered as an EAN-13 barcode by prefixing the ISSN with '977' and appending a two-digit add-on suffix that encodes issue-specific pricing or sequence information. ISSN barcodes appear on the covers of virtually every commercially distributed periodical worldwide, enabling point-of-sale scanning, library check-in systems, subscription fulfillment, and press distribution workflows.
- Eight-Digit Serial Publication IdentifierAn ISSN consists of eight digits in the format XXXX-XXXX, where the final digit is a check character computed using Mod 11 with weights 8 through 2. The check character ensures that any single-digit transcription error is detected automatically. The ISSN identifies the publication title — not an individual issue or volume — meaning every issue of the same journal shares the same ISSN across all editions and formats, unless a format-specific ISSN (print vs. online) has been separately assigned.
- EAN-13 Barcode Encoding with Add-On SuffixISSN barcodes are encoded in EAN-13 format by prepending the prefix '977' to the seven significant ISSN digits (excluding the original check character), followed by a two-digit add-on number and a recalculated EAN-13 check digit. The resulting 13-digit base barcode is typically accompanied by a two- or five-digit supplemental add-on barcode that encodes the issue price or sequence number. This combined structure is defined in the ISSN Manual and is required by most magazine distributors and library suppliers.
- Automatic Check Digit CalculationBoth the Mod 11 ISSN check character and the EAN-13 check digit are calculated automatically by this generator. You only need to supply the raw ISSN number — the encoder handles all check digit computation, the 977 prefix mapping, and the add-on formatting internally. This eliminates the most common source of ISSN barcode errors: manually entered or incorrectly transcribed check digits.
- ISO 3297 and ISSN Manual ComplianceISSN barcodes generated by this tool conform to ISO 3297 (ISSN standard), the ISSN International Centre's ISSN Manual barcode specification, and the EAN/UCC barcode symbology standard for periodicals. The output meets the requirements of the major press distribution networks including Comag, Seymour, Frontline, and EBSCO, as well as library management systems such as Ex Libris, OCLC WorldCat, and Koha.
- Global Use Across Publishing and LibrariesISSN is the universal identifier for serial publications in over 100 countries. Publishers, printers, libraries, and distributors worldwide rely on ISSN barcodes for cover scanning at retail checkouts, library circulation desks, subscription mailrooms, and digital asset management systems. An accurate ISSN barcode on a periodical cover is a prerequisite for commercial distribution through newsstands, bookstores, and library supply chains.

ISSN Barcode Generator Features
Everything you need to create publication-ready ISSN barcodes — from automatic check digit calculation and add-on suffix support to bulk generation, size controls, and lossless SVG output.
Automatic 977 Prefix and EAN-13 Conversion
Enter any valid eight-digit ISSN and the generator automatically applies the '977' ISSN prefix, strips the original check character, appends the add-on sequence digits, and recalculates the EAN-13 check digit — producing a fully compliant ISSN barcode without any manual number manipulation. The human-readable text beneath the barcode displays the correctly formatted ISSN string.
Real-Time Preview as You Type
The barcode preview updates live with every keystroke. See the exact barcode that will appear on your publication cover — including the EAN-13 base symbol, the add-on supplement bars, and the human-readable ISSN text — before downloading or sending to a printer. Invalid ISSN formats are flagged immediately.
PNG and SVG Download
Download your ISSN barcode as a high-resolution PNG for digital proofs, internal documents, and email, or as a lossless SVG for print-ready cover artwork, prepress workflows, and editorial design files. SVG barcodes scale to any size without pixelation, making them ideal for embedding directly in InDesign, Illustrator, or Affinity Publisher layouts.
Adjustable Width, Height, and Quiet Zone
Control the bar height, module width (X-dimension), and quiet zone margins of your ISSN barcode to match your cover layout requirements. Quiet zones — the mandatory blank spaces flanking the barcode — are included at the correct minimum width per the ISSN Manual and EAN-13 specification to ensure reliable point-of-sale scanning.
Human-Readable Text — Show or Hide
Toggle the human-readable ISSN number displayed beneath the barcode on or off. When enabled, the formatted ISSN string is printed below the bars in a standard font — required by most distributors so newsstand staff can visually verify the publication. Disable the HRI for custom cover designs that display the ISSN in a separate typographic treatment.

ISSN Barcode Use Cases & Real-World Examples
ISSN barcodes appear across the entire publishing and library supply chain. Here are the most common real-world applications.
Magazine and Periodical Cover Scanning
Every commercially distributed magazine carries an ISSN barcode on its cover, enabling point-of-sale scanning at newsstands, bookstores, and supermarket checkouts. The barcode encodes the ISSN together with an issue-specific add-on code, allowing retailer POS systems to identify not just the publication title but the specific issue being purchased for inventory reconciliation and returns processing.
Academic Journal and Library Cataloging
University libraries, national libraries, and public library networks rely on ISSN barcodes for serials cataloging, check-in, and circulation workflows. Library management systems use the ISSN to link physical issues to MARC bibliographic records and digital holdings in WorldCat, enabling seamless interlibrary loan requests, e-resource access management, and subscription renewal tracking.
Press Distribution and Fulfillment Networks
Press distributors and subscription fulfillment houses use ISSN barcodes to sort, route, and track periodical deliveries through automated processing systems. Scanners read ISSN barcodes on bundles and individual copies to update delivery manifests, calculate retailer allocations, and process unsold return credits — all without manual data entry.
Subscription and Mailing Label Processing
Magazine subscription mailrooms and mailing bureaus encode ISSN barcodes on subscriber address labels and delivery envelopes. Postal automation systems read these barcodes to apply correct postage rates for periodical mail class, track delivery confirmation, and reconcile subscriber address change requests against the publication's circulation management database.
Newspaper Cover Identification
Daily, weekly, and regional newspapers carry ISSN barcodes for retail identification and distribution tracking. Unlike magazines, newspapers may encode a date-based add-on suffix instead of a price code, allowing wholesalers and retailers to distinguish issues by publication date during high-speed automated scanning on inbound delivery processing lines.
Digital Publishing and Metadata Management
Digital publishers and e-journal platforms use ISSNs to link print and online editions, manage DOI registration, and populate CrossRef, SHERPA/RoMEO, and DOAJ metadata records. ISSN barcodes generated from this tool can be embedded in digital cover images, PDF cover pages, and e-reader metadata fields to maintain consistent title identification across print and digital distribution channels.
ISSN Barcode — Frequently Asked Questions
Technical answers to the most common questions about ISSN encoding rules, the 977 prefix, add-on supplements, check digit calculation, and practical usage for publishers.
What is an ISSN and what does it identify?
An ISSN (International Standard Serial Number) is an eight-digit numeric identifier assigned to a serial publication — any periodical issued in a continuing series under a consistent title, including academic journals, magazines, newspapers, newsletters, yearbooks, and monographic series. Defined by ISO 3297, the ISSN identifies the publication title, not a specific issue or volume. A single title may hold two ISSNs: one for the print edition (print ISSN / pISSN) and one for the online edition (electronic ISSN / eISSN). ISSNs are registered and maintained by the ISSN International Centre in Paris and its network of over 90 national ISSN centers.
How is an ISSN encoded as a barcode?
An ISSN is encoded as a barcode using the EAN-13 symbology with a '977' publication prefix. The encoding process: (1) take the seven significant digits of the ISSN (digits 1–7, excluding the original ISSN check character); (2) prepend '977' to get 10 digits; (3) append a two-digit add-on number (typically '00' if no issue-specific code is needed); (4) calculate the EAN-13 check digit from the resulting 12-digit string. The final 13-digit number is encoded as a standard EAN-13 barcode. A two-digit supplemental add-on barcode is printed to the right of the main symbol to carry the issue sequence or price code.
What is the ISSN check digit and how is it calculated?
The ISSN check digit is the eighth and final character of the ISSN, which may be a digit (0–9) or the letter 'X' (representing 10). It is calculated using Mod 11 with alternating weights 8, 7, 6, 5, 4, 3, and 2 applied to the first seven ISSN digits. The sum of the weighted products is divided by 11; the check digit is 11 minus the remainder (using 'X' if the result is 10, and '0' if the result is 11). This generator computes the check digit automatically — you do not need to calculate or supply it separately. The ISSN check digit is not the same as the EAN-13 check digit used in the barcode.
What is the add-on supplement printed next to the ISSN barcode?
The two-digit add-on supplement to the right of the main ISSN EAN-13 barcode is an optional but widely used extension that encodes issue-specific information — most commonly a sequence number (01, 02, 03…) for each issue within a volume year, or a price code used by press distributors. Some publishers use '00' as a generic placeholder when no issue-specific code is required. The ISSN Manual recommends always including the two-digit add-on to ensure compatibility with distributor scanning systems, even if the value is simply '00'.
What is the difference between a print ISSN and an electronic ISSN?
A print ISSN (pISSN) is assigned to the physical printed edition of a serial publication. An electronic ISSN (eISSN) is assigned to the online or digital edition of the same title. Both are registered separately with the ISSN International Centre. For barcode purposes, only the print ISSN is typically encoded on the physical cover of a printed periodical. Online publications may embed the eISSN in PDF cover pages, HTML metadata, or digital distribution manifests, but a barcode on a physical product always uses the print ISSN.
Is the ISSN barcode the same as an ISBN barcode?
No. ISSN and ISBN are separate international numbering systems for different publication types. ISBN (International Standard Book Number) identifies individual book editions — non-serial, single-issue publications. ISSN identifies serial publications — periodicals issued as a continuing series under a consistent title. Both use EAN-13 barcode encoding, but with different prefixes: ISBNs use the '978' or '979' Bookland prefix, while ISSNs use the '977' prefix. A publication that is both a series title and a standalone volume (such as an annual handbook or conference proceedings) may carry both an ISBN (for that specific issue) and an ISSN (for the series).
What size should an ISSN barcode be on a magazine cover?
The ISSN Manual and EAN barcode specifications recommend a standard size (100% magnification) EAN-13 barcode of 37.29mm wide × 25.93mm tall (excluding quiet zones and the add-on supplement). For magazine covers, barcode widths between 80% and 200% of standard size are acceptable — corresponding to approximately 30–75mm wide. The minimum recommended magnification for reliable retail scanning is 80% (about 29.8mm wide). Always include the mandatory quiet zones: a minimum of 3.63mm to the left, 2.31mm to the right of the EAN-13 symbol, and additional space for the add-on supplement.
Is my publication data safe when using this generator?
Yes. All ISSN barcode encoding is performed entirely in your browser using client-side JavaScript. Your ISSN numbers and any associated publication data are never transmitted to any server and never stored anywhere. Close the browser tab and all data is gone. This tool is safe to use with unpublished ISSN assignments, pre-launch title identifiers, and commercially sensitive distribution codes.
