Chapman Serial Number Lookup: Decode Your Guitar Instantly

A Chapman serial number lookup is the fastest way to identify when and where your guitar was made. Founded in the UK by Rob Chapman and launching publicly around 2010, Chapman Guitars has used a small set of factory partners: World Musical Instruments (WMI) in Korea, Cort in Indonesia, and P.T. Wildwood in Indonesia. Each factory uses a distinct serial format.

Use the free Chapman serial number lookup tool above to instantly decode your serial number. It covers WMI Korea, Cort Indonesia, Wildwood Indonesia, and numeric-only formats — no sign-up required. Enter your number and get production year, factory location, and country in seconds.

Part 1: Where Is My Chapman Serial Number?

Before you can run a Chapman serial number lookup, you need to find the number.

Back of Headstock (Most Common): The vast majority of Chapman guitars have the serial number printed on the back of the headstock, often below the Chapman logo. This is the first place to check for any Chapman made after 2010.

Neck Plate: Some Chapman guitars may have the serial number stamped on the neck plate — the metal plate where the neck bolts to the body.

Control Cavity / Neck Pocket: In rare cases, additional identification numbers may appear inside the control cavity or neck pocket. You may need to remove the back plate to see them.

Pro tip: Serial numbers can be faint, especially on older guitars. Use good lighting and a magnifying glass if needed. On modern Chapman guitars, the serial is typically cleanly printed on the back of the headstock.

What's Next? Now that you know your guitar's year, the next step is setting it up to play its best. Factory specs — action height, pickup height, neck relief — vary between Chapman eras and models. Want to dial in the right specs? Check out our Action Height Guide and Truss Rod Adjustment Guide.

Part 2: WMI Korea Format

World Musical Instruments (WMI) is a premium Korean manufacturer that has produced many Chapman guitars, especially higher-end and early models.

The Format Explained

Position	Characters	Meaning
1-3	WMI	WMI factory identifier
4-5	YY	2-digit year
6+	#####	Production number

Worked Examples

• WMI2212345: WMI = World Musical Instruments, 22 = 2022, 12345 = unit → 2022, World Musical Instruments (WMI), Korea
• WMI1510001: WMI = World Musical Instruments, 15 = 2015, 10001 = unit → 2015, World Musical Instruments (WMI), Korea

Part 3: Indonesia Cort Format

Some Chapman guitars are made by Cort in Indonesia, typically for the Standard line.

The Format Explained

Position	Characters	Meaning
1-2	IC	Cort Indonesia identifier
3-4	YY	2-digit year
5+	#####	Production number

Worked Example

• IC2212345: IC = Cort Indonesia, 22 = 2022, 12345 = unit → 2022, Cort Indonesia, Indonesia

Part 4: Indonesia Wildwood Format

Other Indonesian Chapman guitars are made by P.T. Wildwood.

The Format Explained

Position	Characters	Meaning
1-2	IW	Wildwood factory identifier
3-4	YY	2-digit year
5+	#####	Production number

Worked Example

• IW2212345: IW = Wildwood, 22 = 2022, 12345 = unit → 2022, P.T. Wildwood, Indonesia

Part 5: Short Numeric Format

Some Chapman guitars use a simple 7-8 digit numeric serial without a factory prefix.

The Format

7-8 digits, first two = year, remainder = production sequence

Worked Example

• 2212345: 22 = 2022, 12345 = unit → 2022 (approximate), Korea or Indonesia

Note: Without a factory prefix, the exact country cannot be determined from the serial alone. Check the "Made in" label on your guitar.

Complete reference table for all Chapman serial number prefixes:

Prefix	Year Range	Country	Factory	Notes
WMI + digits	2010-present	Korea	World Musical Instruments (WMI)	Premium Korean manufacturing

IW + digits	2015-present	Indonesia	P.T. Wildwood	Alternative Indonesian factory
7-8 digit numeric	2010-present	Korea or Indonesia	Various OEM	No factory prefix

How to Read Your Chapman Serial Number: Step-by-Step

Follow this process to decode any Chapman guitar from 2010 onward.

1. Locate the serial number on the back of the headstock (most common), neck plate, or inside the control cavity/neck pocket.
2. Check for letter prefixes. WMI = Korea WMI. IC = Indonesia Cort. IW = Indonesia Wildwood.
3. For WMI/IC/IW prefixes: The two digits after the prefix = year, remainder = production number.
4. For numeric only (7-8 digits): First two digits = year. Country is likely Korea or Indonesia — check the "Made in" label.
5. If nothing matches: Compare your serial to the prefix table above, or check for special edition/prototype markings.

Pro tip: If the serial doesn't match any format, the guitar may be a special edition, prototype, or — in rare cases — counterfeit. Check the physical features and consult the troubleshooting guide below.

Chapman Guitar Lines: Understanding the Range

Chapman Guitars offers several model lines, each with different production partners and price points.

ML Series: Signature-style single-cut and double-cut electrics. Often produced in Korea by WMI for higher-end versions and Indonesia for Standard versions.

Standard Series: Entry-to-mid-range models typically built in Indonesia (Cort or Wildwood).

Pro/Signature Models: Higher-spec models often feature premium hardware and finishes, frequently Korean-made.

Different serial systems. Korean Chapman guitars use the WMI prefix. Indonesian Chapman guitars use IC (Cort) or IW (Wildwood) prefixes. Numeric-only serials may come from either region.

Just Got a Used Chapman?

If you're looking up a serial number, you probably just bought a used guitar — congratulations! The next step is getting it set up properly. Used guitars almost always need a fresh setup after changing hands.

Why used guitars need setup:

• Previous owner's string gauge and action preferences may not match yours
• Shipping and climate changes affect neck relief
• Strings are probably due for a change
• Factory setups are often conservative — a custom setup unlocks the guitar's potential

Your next steps:

1. Check Action Height — Learn the correct action for your playing style
2. Adjust Truss Rod — Dial in the right neck relief
3. Choose the Right Strings — String gauge affects tone and playability
4. Check Factory Specs — Find the exact specs for your model
5. Add to My Garage — Track your guitar's setup history

Recommended Strings for Your Chapman

Now that you've identified your Chapman's production year and factory, choose strings that match its era and model. Chapman guitars typically use standard scale lengths, so string selection follows familiar principles:

For Chapman humbucker-equipped models: 10-46 is a common factory standard. For heavier styles, 11-48 or 12-52 provide fuller tone and better tuning stability.

For Chapman with tremolos: Consider a slightly heavier bottom end (10-52 hybrid) to maintain tuning stability under heavy tremolo use.

For Standard Series models: Quality strings can transform these guitars. Upgrade from factory strings to premium nickel-plated steel for immediate improvement.

Authentication Tips: Spotting Fake Chapman Guitars

Serial numbers are your first line of defense against counterfeits. Fake Chapman guitars are uncommon but worth watching for.

Red flags:

• Format doesn't match the claimed origin. A Chapman labeled "Made in Korea" should have a WMI prefix. A Chapman labeled "Made in Indonesia" should have an IC or IW prefix.
• Serial length is wrong. WMI/IC/IW serials are typically 10-12 digits. Numeric-only serials are 7-8 digits.
• Font and printing quality. Genuine Chapman serials are cleanly printed. Blurry, smudged, or poorly aligned text is suspicious.
• Physical features don't match the era. A serial suggesting 2022 production but with hardware and specs from a different era is concerning.

Verification steps:

1. Run the serial through our decoder above. Does the result match the guitar's apparent age and features?
2. Check the "Made in" label. Does the country match the serial prefix?
3. Compare logo style, tuners, and hardware to known examples from that year on Chapman's official site or Reverb listings.
4. For high-value or signature models, consider contacting Chapman Guitars directly for verification.
