Encode a UPC Barcode using our Barcode Font

We're assuming you've got the CarolinaBarUPC_ Normal.ttf file installed. Lets use the sample UPC A code we've been looking at - "644209420957". Here's how you encode it:

  • Using the Orange row, type the first character, or a "6"

  • Using the Blue keyboard row, type the next 5-digits. We're encoding "44209" so we type "RRWPO". Lower or upper case is OK

  • Using the Purple key, type a "-" (dash)

  • Using the Red keyboard row, type the next 5 digits. We're encoding "42095" so we type "FS;LG"

  • Using the Green keyboard row, type the check digit. We're encoding a "7" so we type "M"

So to encode "644209420957", we type "6RRWPO-FS;LGM". Your screen should look like this:
