The serial number should always begin with Nº, an abbreviation for number, Note: there are no exceptions to this rule. The code should nearly always contain one dash, never more, however there are a few exceptions where there are no dashes. The patch will usually include a serial number that consists of at least five numbers, although the exact amount of numbers will vary depending on the model and the year the item was made. It should be the same colour as either the lining or the contrast stitching. This is a leather patch with a small paragraph of text, all written in capital letters, with no spelling mistakes or overlapping letters. In most cases, Coach bags have what is known as a 'creed patch' inside of them. There are a few exceptions to this rule, so best to research your specific bag before jumping to conclusions.

However, if the bag does not have this pattern on the exterior, then it is likely to have it as the lining. If the outside of the bag has this classic 'CC' pattern, then the interior lining should be a solid colour satin material, and should not have the 'CC' print, as this is an indication of a fake. The pattern should line up evenly, and not break at the seams or pockets. The C's should be in sets of two, and within the set they should be facing and touching, mirroring each other. Firstly, the letters should clearly appear as C's, not G's or O's. When it comes to the signature Coach bags with the 'CC' print, the easiest way to spot a fake is to inspect the layout of the pattern.
