Limitations & cautions

A spaced or hyphenated number on a faint scan can confuse OCR. Verify the flags on image pages so no full number remains. The tool masks what it detects; check the output.

Can it read these numbers off a scan?

Yes. Local OCR reads the image first. Always verify faint or skewed pages.
