Why isn't my company name coming up when scanned by my smartphone app?

There may be a few reasons, likely you have not registered your GTIN with the app/store/POS/site/database that the scanner is connected to. More on how to do this here: (How To Register a GTIN)

Until you manually input your product data into a specific POS system/database or pay Google to advertise it, it will come up "no data found". 

For some incorrectly programmed smartphone apps the developers may have it incorrectly coded to pull data directly from GS1’s outdated database. The information on GS1's GEPIR site is outdated and doesn’t record the current owner of that specific UPC/EAN prefix number that was issued before 2002. In short if you own your GTIN (if it's from Bar Codes Talk you own it for life) you would only use our public owner database as a reference point: https://www.barcodestalk.com/gepir

To sum it up, to get your information to appear when scanned contact the store, website or third-party "app" maker and ask them how you can input your data in their system.
