Where is the VIN in the Mercedes-Benz A-Class?

This guide covers the VIN (chassis number) locations on the Mercedes-Benz A-Class W177, produced between 2018–2021, including the easiest label to scan and the more “official” stamped chassis number in the engine bay.

Chassis Number Locations

B-Pillar / Door Jamb VIN Sticker (Right Side)

• Where to look: A black manufacturer label on the right-side B-pillar, near the door latch area, showing the VIN and weight ratings.
• Access: Easy—open the right front door and look at the lower B-pillar area; it’s flat and high-contrast (white text on black).
• Note: This is described on the right side; keep that orientation (don’t assume “driver side”). On LHD cars, this is typically the passenger side.
• Tip: Because it’s clean and flat, you can scan the sticker instantly with your phone to avoid misreading characters like B/8 or O/0.

Engine Bay (Stamped Chassis Number on Firewall/Crossmember)

• Where to look: Stamped directly into the metal at the rear of the engine bay on the firewall/crossmember, slightly to the right of center when you’re facing the engine—hidden under a plastic trim strip/weather seal.
• Access: Open the hood, then locate the plastic cowl at the base of the windshield. Find the small rectangular cutout/flap in the trim and lift it up to expose the stamped VIN.
• Note: This is the “harder to find” physical chassis stamp (and the one you’ll want to match against the sticker/windshield VIN when checking the car).
• Tip: The stamp is often dark/low-contrast and angled—use ScanVin.app’s camera scan in High Contrast AI Mode (and a flashlight) to pull the characters out of the shadows.

Windshield VIN Plate (Bottom Corner)

• Where to look: At the bottom corner of the windshield on the left side of the vehicle (driver’s side on LHD), visible through the glass.
• Access: Easy to see from outside, but reflections and glare can make it annoying to read.
• Note: Best for quick checks in parking lots, but still verify it matches the sticker and the engine-bay stamp.
• Tip: If glare from the sun/dash washes it out, capture it with your phone using the VIN scanner instead of squinting and copying it by hand.

OBD / Diagnostics (Digital VIN via OBD-II or Vehicle Menu)

• Where to look: The VIN can be read digitally through the OBD-II port with a scanner, and may also be accessible through vehicle/MBUX service information menus depending on equipment/software.
• Access: Moderate—requires the car powered on and either an OBD tool or menu navigation.
• Note: Digital VIN is useful for cross-checking, but for identity/anti-tamper checks you still want to match the physical VIN locations.
• Tip: If you’re comparing multiple sources quickly, scan the physical VIN with your phone so you’re not stuck typing a 17-character code in the cabin.

• Shows the hidden firewall/crossmember stamped chassis number under the plastic flap in the engine bay, plus related under-hood points of reference.

Common Problems & Troubleshooting

• “I can’t see the stamped VIN in the engine bay.” Lift the small plastic flap at the base of the windshield cowl, then use a flashlight; the stamp can be body-colored and shadowed.
• “The windshield VIN is unreadable.” Change your viewing angle to reduce glare, shade the area with your hand, and clean the glass—reflections are the #1 issue here.
• Sticker warning: A door-jamb VIN label is convenient, but it can be missing, replaced, or damaged—always cross-check it against the windshield VIN and the engine-bay stamped chassis number.

This guide shows where to locate the VIN (chassis number) on the Mercedes-Benz A-Class W176 produced between 2012 and 2017, using the most common factory placements on the body and inside the cabin.

Chassis Number Locations

1) B-Pillar Label (Driver’s Door Jamb)

• Where to look: Open the driver’s door and inspect the B-pillar (the post between the front and rear doors). Look low on the pillar near the rocker panel/sill for a black VIN/vehicle data sticker.
• Access: Easy access on a vertical surface; no tools needed. Sticker condition can vary (peeling/fading over time).
• Note: The example vehicle is LHD. On RHD cars, you’ll typically find the equivalent label on the driver’s side (right side).
• Tip: If the print is faint or you don’t want transcription mistakes, scan the label directly with your phone while holding the camera square to the sticker.

2) Windshield (Dashboard VIN Plate)

• Where to look: Stand outside the car and look through the bottom corner of the windshield on the driver’s side (left side on LHD). The VIN sits on a plate mounted on top of the dashboard.
• Access: Very quick to check, but reflections from sky/clouds can make it hard to read; dirty exterior glass also blocks characters.
• Note: On RHD cars, this windshield VIN position typically swaps to the right side.
• Tip: When glare is bad, capture it instantly using the VIN scanner from a slight angle instead of trying to read each character through reflections.

3) Floor (Under Front Passenger Seat / Footwell Carpet Flap)

• Where to look: Inside the cabin, move to the front footwell floor and find the pre-cut rectangular carpet flap with a small plastic clip/tab. Lift it to expose the VIN stamped into the metal cross-member/structural beam (commonly on the right side for LHD vehicles, but check the driver side footwell if not found).
• Access: Dark and recessed; you’ll likely need to hold the carpet flap open while viewing/scanning the stamping.
• Note: This is a stamped chassis VIN (hard to fake compared to a sticker), so it’s a key verification point when buying.
• Tip: Because it’s in deep shadow, use the flashlight + OCR scanner so you’re not fighting the darkness while bent over the footwell.

4) B-Pillar Label (Passenger Side Door Jamb) – Alternate/Backup

• Where to look: Open a door on the right side and check the B-pillar for another black manufacturer label (often a tire-pressure placard that also lists the VIN near the top).
• Access: Easy access; great redundancy if the driver-side label is damaged.
• Note: This is a useful backup location—especially on vehicles where one jamb sticker has been replaced or worn.
• Tip: If you’re comparing multiple labels quickly, scan and save the VIN straight from the sticker instead of re-typing it each time.

• Handheld walkthrough showing the floor chassis stamp, windshield plate, and two door-jamb labels on a real Mercedes-Benz A-Class W176.

Common Problems & Troubleshooting

• Windshield glare/reflections: Change your viewing angle, shade the VIN area with your hand, and clean the outside glass to reduce sky reflections.
• Floor VIN too dark to read: Lift the carpet flap fully and add light—this stamping sits low and is easy to miss in shadows.
• Sticker vs. stamped VIN: Door-jamb stickers can peel, fade, or be replaced—always cross-check against the stamped floor VIN for a proper identity verification.

This guide shows you where to find the VIN (vehicle identification number) on the Mercedes-Benz Klasa A (W169) [2005-2005].

Chassis Number Locations

1) B-Pillar VIN Label (Passenger Side)

• Where to look: Open the front passenger door. Locate the black sticker on the lower section of the B-pillar (the center pillar between front and rear doors). This label typically shows the VIN, paint codes, and weight limits.
• Access: Low difficulty. Usually clean and high-contrast, but the sticker can fade, crack, or peel on older cars.
• Note: On LHD vehicles, this is typically on the right side (passenger side).
• Tip: If the print is faded, use the camera to scan the label directly with ScanVin.app so you don’t misread similar characters (like 8/B or 5/S).

2) Firewall / Engine Bay Stamped VIN (Under Access Flap)

• Where to look: Open the hood. Find the plastic ventilation cover below the windshield wipers. Look for a small rectangular access flap in the rubber/plastic trim near the center-right (viewed from the front of the car). Lift the flap to reveal the VIN stamped into the metal firewall/bulkhead underneath.
• Access: Medium difficulty. Often dusty/dirty, and the flap plastic can be brittle with age. You may need to wipe/scrub the stamping for visibility and use a light because it’s recessed.
• Note: Best checked with the engine off and the hood safely supported.
• Tip: After wiping the area, use High Contrast AI scanning in ScanVin.app to pick up stamped characters that are hard to see in shadows and grime.

3) Windshield / Dashboard VIN Area (Market-Dependent)

• Where to look: From outside the vehicle, check the bottom corner of the windshield where the dashboard meets the glass (often driver-side, but can vary by market).
• Access: Medium–High difficulty. If present, it can be obscured by the windshield frit (dot matrix) and glare/reflections can make it hard to read.
• Note: On early W169s, a windshield VIN plate is not guaranteed in every market.
• Tip: To beat glare and reflections, capture the VIN with your phone using ScanVin.app instead of trying to read it at an angle and typing it manually.

4) Instrument Cluster / Digital Display (On-Board Computer)

• Where to look: With the ignition on, use the steering wheel menu buttons to navigate vehicle info screens and display the VIN on the instrument cluster (if equipped/configured).
• Access: Medium difficulty. Requires key-on and correct menu navigation; camera flicker can also affect readability.
• Note: Menu layout depends on trim/options.
• Tip: If the display flickers on camera, take a steady close shot and use ScanVin.app to scan the screen cleanly to avoid transcription mistakes.

5) Under Front Floor Carpet / Chassis Stamping (Structural VIN)

• Where to look: Stamped on the floor cross-member structure, roughly under the front right seat/floor area (shown on a stripped chassis).
• Access: High difficulty. Typically not accessible without removing interior trim/carpeting.
• Note: Check the front footwell floor (commonly on the passenger side for LHD vehicles, but check the driver side footwell if not found).
• Tip: If you’re doing a deep inspection and it’s dark under the seat/carpet area, use ScanVin.app with flashlight + OCR so you don’t have to write the number down in an awkward position.

▶ Watch Mercedes-Benz Klasa A VIN Location Guide

• Walk-around on a Mercedes A-Class (W169) showing the B-pillar label, the firewall stamping under the access flap, and the windshield VIN area.

Common Problems & Troubleshooting

• Brittle access flap in engine bay: If the plastic cover feels fragile, pry gently and don’t force it—warm weather helps plastics flex instead of cracking.
• Dirty or low-contrast firewall stamping: Scrub/wipe the metal and use a strong light; stamped characters disappear fast under dust and shadows.
• Sticker is not “proof” by itself: A missing/peeling B-pillar label can happen after repaint/repairs—always cross-check the VIN against a stamped location when buying.
