These numbers help identify the organization that issued the card.

This attention to detail is what makes the tool reliable for verifying card numbers.
Different Ways to Input Your Numbers into a Card Validator

The tool is set up to handle both ways, which means you do not have to format the number in a special way before you enter it. This makes the process a bit smoother for the user, you know, reducing any extra steps.
