Checks before you use the output
Read the human-readable line and confirm whether your system expects the start and stop letters to be visible. This tool hides them in the caption, which is normal.
Questions and answers
What are the start and stop letters?
A, B, C, or D. They are not part of the number. A is added when you omit them.
Can it encode letters in the middle?
No. Only the start and stop positions use A–D.
Is this Code 39?
No. They are different symbols.
