THIS IS ANCIENT VERSION OF CALCULLA.COM LEFT HERE FOR ARCHIVAL PURPOSES.
ALL CALCULATORS SHOULD STILL WORK, BUT YOU CAN'T BE SURE. WE ALSO DON'T UPDATE THEM, SO EXPECT OUTDATED INFO.
OUR SUGGESTION IS TO MOVE TO RECENT VERSION OF CALCULLA.COM BY CLICKING THE LINK: Is ID Number Correct
Is ID Number Correct
The online calculator for checking correctness of ID numbers. It validates: IBAN (bank account number), EAN (article), ISBN (book), ISMN (music), ISSN (serial). Just enter the code (with or without any dots, spaces, slashes etc.) and in a moment you will know, if it is a valid code and which one of them.
What is the meaning of each calculator field ?

    You can enter any dots, dashes, commas, whitespaces etc. This calculator will just ignore them. It will consider only characters meaningful for the detection process.
  • 2. The calcullator detects automagically what kind of number it is. And reports "FOUND !" in row of IBAN, ISBN, ISSN or EAN - this means the number (or code) is correct.
  • 3. There is also "plain code" row, where you can find the plain number - all non-meaningful characters are filtered-out.
