Bates numbers are an invaluable tool of legal document indexing for attorneys. The Bates numbering of legal PDF files helps to provide accurate, and even the largest PDF file is just one size. The number in a PDF depends on the number size of a legal document. If you look around at a particular file size or document, many are in the hundreds. However, it's not always just one size. A single size may vary from a very small file to a large file. The reason for this is that PDF files have many layers of information hidden beneath, this can cause the PDF file size to vary a great deal, in some cases up to three hundred. The biggest reason for this is the layout of a legal document. All pages are numbered, but in some document layout it is not possible to know the correct Bates number, this can make the search especially difficult and tedious. Another thing that often varies between all pages is the order of page numbers. This can cause even a single PDF file to have a lot of different size. Many legal document indexing tools use a specific type of numbering system called “Counters” In the case of legal document indexing tools the number that you use for the bates numbers of a legal document depends on the document layout. In the case of the above-mentioned legal document indexing tools the Bates numbers are all the size of a single page; so if your legal document contains a series of page by page number, they will usually be set to number the page by page in alphabetical order (e.g. A001 — A0006). This is a common way of representing bates numbers of certain legal documents — because it just is better to use the traditional numbering system than to use a complicated and complicated system which are not always understood by an ordinary user. If your document is in an A1 format and has a single file sized PDF file, then your Bates numbering of legal document will be set to the file size of the PDF. The main reason for this is to make it easy for the users, and easier for you to use. But sometimes, it's not that easy. Sometimes a particular legal format needs to have different sized pages of bates numbers to be understandable. And some legal file formats can have no Bates numbering at all. So these cases are considered “special”; they're either hard to deal with, or simply don't make good sense for the use case.
