We use a tracking number based authenticity checker to let customers check if they bought an authentic Aifi expanding diaper bag. Please input the tracking number you received in your shipping confirmation email from support@aifibags.com. If your tracking number works, your Aifi bag is authentic and was purchased from Aifi LLC. If you bought a non-authentic Aifi bag, you will get a message that says "Could Not Find Order." Always make sure to check the url (aifibags.com) when purchasing from Instagram or Facebook. Give about 24 hours before checking authenticity after receiving the shipping confirmation email.
