Bag Detective is an online luxury handbag authentication service focused on helping shoppers make more confident decisions when buying pre-owned designer bags. The company’s experts review item photographs and provide written opinions on authenticity, with services covering Louis Vuitton, Chanel, Dior and Gucci. Its mission is to help luxury handbag lovers find desired pieces at lower prices while supporting sustainability through the resale market.

Customers can choose from several authentication levels. The Basic option provides a written verdict after a professional review of submitted photos, generally within 24 hours. Standard adds an online Certificate of Authenticity with QR code protection and the bag’s date code or serial number. Premium includes those features plus a detailed explanation of the assessment, supported by more than ten photo examples. The tiers are presented for needs such as checking a prospective purchase, reassuring a buyer before resale, or supporting an eBay or PayPal dispute. Additional options include item identification, price assessment and reviews of newer items or exotic leather.
