My barcode scans and shows number, but displays the wrong format

[myuseraccount]

I have a library card that the camera scans successfully and captures the number, but the displayed barcode doesn't match the card. In fact, when I go to edit the entry, none of the displayed barcode options are correct. It seems that the scanning library supports other barcode formats than the ones in the list, but it just randomly guesses one when it doesn't actually support that one for display within the app. Took me awhile to figure out why it wouldn't scan off the screen.

How do I find out what format the barcode is, so I can request support for this type? IMG_20190530_103413

Found a tool online that reads it: it says it's just Codabar, but neither this app nor another one I tried gives the correct bar output. I did get an error, from Skunk for Pebble: "Codabars must begin and end with A, B, C, or D!"
