GS1 aplikacijski identifikator (AI)
Aplikacijski identifikator GS1 je predpona iz dveh do štirih števk, ki čitalniku pove, kaj pomenijo podatki, ki ji sledijo. AI 01 označuje GTIN, 10 številko serije, 17 rok uporabnosti. Šele z AI lahko ena črtna koda hkrati vsebuje več polj, za kar so zasnovane kode GS1-128, GS1 DataMatrix in GS1 DataBar.
Spodnja tabela navaja vse identifikatorje AI, ki jih določa GS1, z njihovim uradnim kratkim nazivom in formatom podatkov. Identifikatorji, nazivi in kode formatov so del standarda GS1 ter so zato navedeni v izvirnem zapisu in niso prevedeni.
Kako brati format podatkov: N pomeni števke, X alfanumerični nabor znakov standarda. Sama številka pomeni fiksno dolžino, zato N14 pomeni natanko štirinajst števk. Dve piki pomenita spremenljivo dolžino do te največje vrednosti, torej X..20 pomeni do dvajset znakov. Znak plus povezuje dele sestavljenega polja, oglati oklepaji pa označujejo izbirni del. Identifikator, zapisan kot razpon, na primer 3100-3105, z zadnjo števko določa število decimalnih mest.
Dva identifikatorja v viru nimata kratkega naziva, zato je njun stolpec z nazivom prazen.
