Many people want to spot a fake designer bag, since there are lots of counterfeit bags out there, and some of them look very close to the real thing. But if you know what to look for, you can learn to tell the difference like a pro—even as a beginner.
Let’s walk through the steps and secrets experts use to spot a fake.
1. Look for a Secret Code Inside the Bag
Designer bags often include a hidden serial number or date code stamped or printed inside.
Louis Vuitton (pre‑2021) date codes (e.g., “SP1021”) show factory and production date. Learn how to read them in Fashionphile’s Louis Vuitton Date Code Guide.
After 2021, LV replaced visible codes with tiny microchips.
Chanel uses serial stickers and matching cards—see Rebag’s Chanel serial code chart.
Watch for:
Missing codes
Incorrect digits or letters
Codes that don’t match the bag’s age/style
2. Check the Logo and Inside Tag
Luxury brands use precise fonts and layouts.
Louis Vuitton heat stamps have clean letters; the “O” is perfectly round and “T”s nearly touch.
Gucci tags read “GUCCI” in uppercase with “made in italy” below, and 10–13‑digit serials. See Collector’s Cage’s Gucci guide.
Chanel serial stickers include holograms, strike-through zeros, and specific adhesive placement. Use Xupes’s Chanel serial guide.
Red flags: misspelled logos, odd fonts, off‑center tags.
3. Study the Stitching
Real designer bags have perfect, even stitches.
Match stitch count on both sides
Stitches should be loose‑thread and glue‑free
Color must fit brand norms (e.g., Louis Vuitton’s mustard‑yellow)
Fake signs: uneven length, inconsistent color, sloppy seams.
4. Feel the Zippers and Hardware
High‑end bags use solid, cool, heavy metal hardware with precise engraving.
LV zippers and pulls should feel sturdy with clean branding
Fake hardware often feels hollow or rough.
5. Use Your Nose
Real leather has a genuine, mild scent. Fake bags often smell like plastic or glue. Trust your senses.
6. Inspect the Inside Lining
Authentic bags use premium linings like suede or microfiber. Patterns are symmetrical.
Fake bags may show cheap, shiny lining or mismatched seams.

7. Packaging Tells a Story
True designer packaging—dust bags, boxes, care cards—is always high quality. Fake versions are often flimsy or mismatched.
8. Ask Questions and Compare
Compare with official guides: Fashionphile’s authentication page or The RealReal’s authenticity center
Post comparison photos on forums like PurseForum
Ask yourself:
Does it match real examples?
Is the inside material and color correct?
Are logos, serials, and stitching exact?
Trust your instincts—if something feels off, skip it.
Quick Checklist to Spot a Fake

Text and fonts are correct?
Stitching is even and clean?
Hardware is heavy and well‑engraved?
