look at the internal coach logo. All genuine Coach handbags will have a logo on the inside near the zipper. This logo may be a trademark pattern or a traditional leather trademark. If there is no trademark in it, or the trademark is printed on other materials, then the bag may be fake, see the internal verification code (credo patch). The verification code is a series of numbers printed inside Coach bags, but some small bags such as clutch, swingpack and mini don't have verification codes. The last four digits of the verification code are composed of letters and numbers, which are the style codes of the bag.

check the lining. If there is Coach's classic CC pattern on the periphery of the lining, there will never be one inside. And if there is a CC pattern inside, then there will never be one outside; Sometimes, there is no CC pattern on the whole lining. If the whole lining of your bag is printed with CC pattern, then this bag is definitely fake.
