A Cort serial number lookup is the fastest way to identify when and where your guitar was made. Cort has built guitars in Korea, Indonesia, China, and Japan since the late 1970s — both under its own Cort brand and as a major OEM for Ibanez, Schecter, ESP/LTD, and many others. Whether you own a Korean-made Cort from the 1990s, a modern Indonesian electric, or a vintage import, the serial number holds the key.
Use the free Cort serial number lookup tool above to instantly decode your serial number. It covers the most common Cort formats — C-prefix, CP-prefix, W-prefix, I/IE-prefix, K-prefix, J-prefix, and numeric-only serials — no sign-up required. Enter your number and get production year, factory location, and country in seconds.

Before you can run a Cort serial number lookup, you need to find the number. Cort serials are usually easy to locate.
Back of Headstock (Most Common): The vast majority of Cort guitars — both own-brand and OEM builds — have the serial number printed or stamped on the back of the headstock. Look near the top, often below the "Cort" logo. This is the first place to check on any Cort made after the early 1990s.
Neck Plate: Some older Cort-made guitars, particularly those built for other brands in the 1980s and 1990s, may have the serial number stamped on the neck plate — the metal plate where the neck bolts to the body.
Control Cavity: In rare cases, additional identification numbers may appear inside the control cavity. You may need to remove the back plate to see it.
Pro tip: Serial numbers can be faint, especially on older guitars. Use good lighting and a magnifying glass if needed. On modern Cort guitars, the serial is typically cleanly printed on the back of the headstock.
The tool at the top of this page is a free Cort serial number checker. Enter your serial number and it instantly returns your guitar's production year, manufacturing location, factory name, and era. No sign-up required — use it as often as you need to verify a single guitar or compare multiple instruments.
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 Cort eras and models. Want to dial in the right specs? Check out our Action Height Guide and Truss Rod Adjustment Guide.
The most common format for Cort's own-brand Korean guitars uses a single-letter "C" prefix followed by eight or more digits.
| Position | Characters | Meaning |
|---|---|---|
| 1 | C | Cort Korea identifier |
| 2-3 | YY | 2-digit year |
| 4-5 | MM | Month (01-12) |
| 6+ | #### | Production number |
Some premium or Custom Shop Cort guitars use a "CP" prefix instead of a single "C".
| Position | Characters | Meaning |
|---|---|---|
| 1-2 | CP | Cort Premium/Custom identifier |
| 3-4 | YY | 2-digit year |
| 5-6 | MM | Month (01-12) |
| 7+ | #### | Production number |
Cort and World Musical Instruments (WMI) share deep manufacturing ties in Korea. Some Cort-affiliated guitars use a "W" prefix that decodes identically to the C-prefix format.
| Position | Characters | Meaning |
|---|---|---|
| 1 | W | WMI factory identifier |
| 2-3 | YY | 2-digit year |
| 4-5 | MM | Month (01-12) |
| 6+ | #### | Production number |
Modern Cort guitars are frequently made in Indonesia. These serials start with "I" or "IE".
| Position | Characters | Meaning |
|---|---|---|
| 1-2 | I or IE | Cort Indonesia identifier |
| 3-4 | YY | 2-digit year |
| 5-6 | MM | Month (01-12) |
| 7+ | #### | Production number |
Older Cort and Cort-made guitars sometimes used K-prefix or J-prefix serials.
| Position | Characters | Meaning |
|---|---|---|
| 1 | K | Korea identifier |
| 2-3 | YY | 2-digit year |
| 4-5 | MM | Month (01-12) |
| 6+ | #### | Production number |
J-prefix serials are less common on Cort-branded instruments and usually indicate Japanese-origin production or OEM builds for other brands. If your guitar is labeled "Made in Japan" with a J-prefix, treat it as a Japan-built instrument rather than a standard Cort import.
Some older Cort guitars from the 1990s and early 2000s used numeric-only serials without a factory prefix.
7-8 digits, first two = year, remainder = production sequence
Note: Without a factory prefix, the exact country cannot always be determined from the serial alone. Check the "Made in" label on your guitar.
Complete reference table for all Cort serial number prefixes:
| Prefix | Year Range | Country | Factory | Notes |
|---|---|---|---|---|
| C + digits | 1990s-present | Korea | Cort Korea | Most common own-brand Cort format |
| CP + digits | 2000s-present | Korea | Cort Korea (Premium) | Higher-end / Custom Shop lines |
| W + digits | 1990s-present | Korea | World Musical Inst. | Cort-affiliated WMI production |
| I + digits | 2000s-present | Indonesia | Cort Indonesia | Modern Indonesian production |
| IE + digits | 2000s-present | Indonesia | Cort Indonesia | Alternate Indonesian prefix |
| K + digits | 1990s-2000s | Korea | Cort Korea | Older Korean format |
| J + digits | Varies | Japan/Other | Various OEM | Usually non-Cort-branded |
| 7-8 digit numeric | 1990s-2000s | Korea | Cort Korea | Early format without prefix |
Follow this process to decode any Cort from 1990 onward.
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.
Many guitar owners are surprised to learn that Cort has built instruments for dozens of well-known brands.
Cort-branded guitars: These are sold under the Cort name worldwide. They cover electric guitars, basses, acoustics, and ukuleles at all price points from budget to premium.
OEM manufacturing: Cort and its affiliated factories have produced guitars for Ibanez, Schecter, ESP/LTD, Gretsch, and others. If you have one of those brands, your serial may decode on the brand-specific decoder pages rather than this Cort page.
Same factories, different labels: A serial starting with "IC" on a Schecter means "Cort Indonesia." A serial starting with "I" or "IE" on a Cort-branded guitar also means Indonesia. The prefix logic is similar, but the brand label tells you which decoder to use.
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:
Your next steps:
Serial numbers help determine a guitar's age, but condition and playability are what really drive value. A well-setup guitar with proper action and intonation can sell for 10-20% more than one that plays poorly.
Key factors that affect Cort value:
If you're selling or just want your guitar playing its best, a proper setup is the highest-ROI improvement you can make.
Now that you've identified your Cort's production year and factory, choose strings that match its era and model.
For Cort electric guitars with humbuckers: 10-46 is the factory standard. For heavier styles, 11-48 or 12-52 provide fuller tone and better tuning stability.
For Cort guitars with tremolos: Consider a slightly heavier bottom end (10-52 hybrid) to maintain tuning stability under heavy tremolo use.
For entry-level Cort models: Quality strings can transform these guitars. Upgrade from factory strings to premium nickel-plated steel for immediate improvement.
Cort guitars are solid workhorses, and proper maintenance keeps them playing their best.
String care: Fresh strings with regular cleaning extend playability and tone significantly. Cort guitars with tremolo bridges especially benefit from fresh strings.
Tremolo bridges: Many Cort electric models feature tremolos. Keep the knife edges lubricated, check saddle intonation, and ensure the nut clamps securely on locking designs.
Pickup height: Cort pickups benefit from proper height adjustment. Active pickups (common on some metal-oriented Cort models) have different optimal heights than passive pickups.
Hardware upgrades: Many Cort players upgrade tuners and bridges. Quality upgrades on a well-maintained Cort can rival guitars costing twice as much.
Serial numbers are your first line of defense against counterfeits. Fake guitars are common, especially for popular models.
Red flags:
Verification steps:
The Mystery: A Cort G Series with serial W15031001. The owner wasn't sure if it was genuine Cort production.
The Investigation: The W prefix indicates WMI (World Musical Instruments) in Korea, a factory closely tied to Cort. The "15" = 2015, "03" = March. The guitar was labeled "Made in Korea."
The Solution: This was a legitimate 2015 Cort-affiliated Korean build. W-prefix serials are common on Korean Cort and Cort-related production.
Takeaway: C and W both point to Korean production. I/IE point to Indonesia. The prefix is definitive for origin.
The Mystery: A Cort with serial I120426682. The owner couldn't read the format because it had nine digits after the prefix.
The Investigation: The I prefix indicates Cort Indonesia. The "12" = 2012, "04" = April, and "26682" is the production number. Longer numbers simply reflect higher production volume.
The Solution: This was a genuine April 2012 Cort Indonesia guitar.
Takeaway: Don't be thrown by a long production number. The YYMM structure is consistent.
The Mystery: A 1990s Cort bass with serial 9812056. The owner wasn't sure if it was Korean or Indonesian.
The Investigation: Numeric-only Cort serials from this era are typically Korean. The "98" = 1998, "12056" = production number. The "Made in Korea" label confirmed it.
Takeaway: Numeric-only serials usually indicate older Korean production, but always verify with the "Made in" label.
Serial number dating is the first step to valuing your Cort. Once you know the year and factory, you can estimate market value.
Korean Cort guitars generally offer excellent value and solid build quality.
Indonesian Cort guitars are common modern imports.
Higher-end Cort instruments command better prices.
Condition is the most important factor. Mint examples command 20-30% premiums over "good" condition.
Model line matters significantly. Premium/Custom Shop > standard import lines.
Country of origin affects collectibility. Older Korean models are generally more sought after than Indonesian equivalents.
Originality matters for higher-end models. Original pickups, hardware, and finish add value.
Signature models often hold value better due to artist association and limited production.
Check all common locations: back of headstock first, then neck plate. Use good lighting and a magnifying glass. Serial numbers can be small and faint, especially on older guitars.
Modern Cort serials are printed in ink and can fade over time. Try different lighting angles. UV light can sometimes reveal faded ink. Take a photo and enhance contrast digitally. Even partial characters can help narrow down the format.
Cort serials vary significantly by factory and era. If the lookup tool returns "Unknown Format," compare your serial to the prefix tables above. Check for non-standard prefixes. Some OEM builds for other brands may use formats not covered on this page.
Check the "Made in" label on the back of the headstock or inside the control cavity. Korean Cort serials usually start with C, CP, W, or K. Indonesian Cort serials start with I or IE. The label and prefix together are definitive.

A Cort serial number decoder interprets the characters in your serial number to determine production year, factory location, and country of origin. Our decoder covers Korean and Indonesian Cort guitars from 1990 to present.
On most Cort guitars, the serial number is on the back of the headstock. Some older models may have it stamped on the neck plate.
For C/CP/W/I/IE/K prefixes, use our lookup tool — the YY digits after the prefix indicate year. For numeric-only serials, the first two digits indicate year. For J-prefix or unclear formats, compare features and "Made in" label to known production eras.
Yes. The tool at the top of this page is a free Cort serial number checker. Enter your serial for instant results — production year, factory, and country. No sign-up or payment required.
Both indicate Korean production. C-prefix serials come from Cort Korea's own production. W-prefix serials come from World Musical Instruments (WMI), a closely related Korean factory. Both follow the same YYMM + production number structure.
Korean Cort guitars from the 1990s-2000s are generally regarded as having better hardware and quality control than entry-level Indonesian models. However, modern Indonesian Cort production has improved significantly, and many current models are excellent instruments.
Value depends on model line, year, condition, and country. Korean Cort guitars typically range from $200-$800 (up to $1,500+ for premium models). Indonesian Cort guitars typically range from $150-$500. Condition and originality are the biggest factors.
The two digits after the C indicate the year. In C22051234, "22" = 2022. In C15031001, "15" = 2015. The next two digits are the month.
Yes. Older Korean Cort guitars from the 1990s-2000s are increasingly collectible, especially well-maintained premium models and signature instruments. Vintage Cort-made guitars for other brands can also hold value.
Check that the serial format matches the "Made in" label (C/CP/W/K = Korea, I/IE = Indonesia). Verify the headstock logo, hardware, and pickups match the claimed model. Compare to official Cort product photos. For high-value models, contact Cort directly.
CP indicates a premium or Custom Shop Cort guitar built in Korea. It follows the same YYMM + production number structure as C-prefix serials.
