GS1 Application Identifier (AI)
GS1 Application Identifier ialah awalan dua hingga empat digit yang memberitahu pengimbas maksud data yang mengikutinya. AI 01 menandakan GTIN, 10 nombor kelompok, 17 tarikh luput. Hanya dengan AI sesebuah kod bar dapat membawa beberapa medan serentak, yang merupakan tujuan reka bentuk bagi GS1-128, GS1 DataMatrix dan GS1 DataBar.
Jadual di bawah menyenaraikan setiap AI yang ditakrifkan oleh GS1, bersama tajuk ringkas rasmi dan format datanya. Pengecam, tajuk dan kod format ialah sebahagian daripada piawaian GS1 dan oleh itu dikekalkan dalam tatatanda asal tanpa diterjemahkan.
Cara membaca format data: N bermaksud digit, X bermaksud set aksara alfanumerik piawaian tersebut. Nombor sahaja mewakili panjang tetap, jadi N14 bermaksud tepat empat belas digit. Dua titik bermaksud panjang boleh ubah sehingga nilai maksimum tersebut, jadi X..20 adalah sehingga dua puluh aksara. Tanda tambah menggabungkan bahagian-bahagian medan komposit, dan tanda kurung siku menandakan bahagian pilihan. Pengecam yang ditulis sebagai julat, seperti 3100-3105, menggunakan digit terakhirnya untuk menunjukkan bilangan tempat perpuluhan.
Dua pengecam tidak mempunyai tajuk ringkas dalam sumber, itulah sebabnya lajur nama masing-masing dibiarkan kosong.
