Part 1: Where Is My LTD Serial Number?

Before you can run an LTD serial number lookup, you need to find the number. LTD has used two primary locations over the decades.

Back of Headstock (Most Common): The vast majority of LTD guitars — especially modern models — have the serial number printed or stamped on the back of the headstock. Look near the top, often under or beside the "LTD" logo. This is the first place to check on any LTD made after the late 1990s.

Neck Plate (Vintage): Some early LTD guitars from the 1990s and early 2000s carry the serial on the neck plate — the metal plate where the neck bolts to the body. If nothing is on the headstock, check the plate.

Body Interior: A few LTD models, particularly semi-hollows and some Indonesian-built models, stamp the serial inside the control cavity or on the neck pocket. If you can't find it on the headstock or plate, remove the control cavity cover.

Pro Tip: Cross-check the serial against the "Made in" label on the back of the headstock or the body. Korea (WMI), Indonesia (Wildwood or Cort), and China all have different prefix letters — if the label and the prefix disagree, the guitar may have been tampered with.

Part 2: LTD Korea — World Musical Instruments (WMI)

Most higher-end LTD models are made in Korea by World Musical Instruments (WMI). The modern WMI format has been in use since the late 1990s and is the most common LTD serial you'll encounter.

The Format Explained

Worked Example

• W22051234: W = WMI, 22 = 2022, 05 = May, 1234 = unit → May 2022, World Musical Instruments (WMI), Korea

Part 3: LTD Early Korean Formats (c.2000–2003)

Early LTD guitars from the early 2000s used single-letter prefixes before standardized numbering took over.

Format

E, R, or U + year digit (0-9) + 5-digit unit number

Worked Example

• E212345: E = Sung-Eum, 2 = approximately 2002 → ~2002, Sung-Eum factory, Korea

The first digit after the letter usually indicates the year (0 = 2000, 1 = 2001, and so on). This numbering style was used around 2000-2003, so treat the decoded year as approximate.

Part 4: LTD Indonesia

LTD has used two primary factories in Indonesia: P.T. Wildwood and Cort Indonesia.

Wildwood Format (IW Prefix)

Example: IW22051234 = 2022, May, Wildwood Indonesia

Cort Format (I Prefix)

Example: I220512345 = 2022, May, Cort Indonesia

Early variant (c.1997-2000): Cort Indonesia also used a single-digit year format: I + Y + MM + 4-digit production number. For example, I9051234 = approximately 1999, May.

Part 5: LTD China

LTD guitars made in China use single-letter factory codes.

The Format

Worked Example

• B22051234: B = Factory B, 22 = 2022, 05 = May → May 2022, LTD China (Factory B)

The ESP Connection: LTD vs ESP

LTD is ESP's import line, launched to make ESP designs affordable outside Japan. The serial prefixes make the relationship obvious — and whether you're dating an EC-1000, an MH-1000, a Viper, or a Phoenix, the factory code tells you where it was built.

ESP (the parent): Hand-built ESP Custom Shop and Original Series guitars come from Japan (E/ES prefixes on modern models, K/S/T/SS/CH/TH/N factory letters from 2000-2015) and from the ESP USA shop in North Hollywood (US prefix). These are the premium tier — expect $800-$5,000+ depending on model and spec.

LTD (the import line): LTD guitars are built in Korea (WMI), Indonesia (Wildwood, Cort) and China to ESP-designed specs at accessible prices. Deluxe-line models (EC-1000, MH-1000, SN-1000, and similar) get premium features like stainless frets, Seymour Duncan or Fishman pickups, and better hardware.

Rule of thumb: a Japanese or USA prefix means the guitar is an ESP, not an LTD. If you decode an "E" or "US" serial, you're looking at an ESP — head to our ESP Serial Number Lookup page for the full ESP reference.

Recommended Strings for Your LTD

LTD guitars are built for high-output play — the EC (Eclipse), MH, EX, and Viper models all ship with aggressive pickups. For most LTDs:

• EC-1000 / MH-1000 / SN-1000 (25.5" or 24.75" scale): .010-.046 for standard, .011-.048 for drop-C and below. Many players prefer hybrid sets for the lighter high strings.
• Viper / Phoenix (set-neck, 24.75"): .010-.046 keeps the vintage-voiced pickups balanced and the bends fluid.
• Bass models (with passive pickups): .045-.100 is the standard factory gauge.

Check your string gauge against neck relief and pickup height after a change — see our String Gauge Guide and Pickup Height Guide for the exact measurements.

Essential Maintenance for Your LTD

• Truss rod: adjust for neck relief (usually 0.008"-0.010" at the 8th fret) — Truss Rod Adjustment Guide
• Action: 1.5mm-2.0mm on the high E at the 12th fret is a good starting point for .010s
• Pickup height: start flush with the pickguard, raise until balanced — closer on the bridge pickup for more drive
• Tremolo (if fitted): keep the knife edges lubricated and the claw springs balanced

Authentication Tips: Spotting Fake LTD Guitars

LTD's affordability makes it a popular counterfeit target, especially at the budget end. Check these:

1. Serial format vs "Made in" label — the prefix letter must match the country on the label (W = Korea, IW/I = Indonesia, B/C/D = China). Mismatch = red flag.
2. Headstock logo — genuine LTD logos are cleanly applied; fakes often have blurry or misaligned decals.
3. Model badge & specs — check that the model name matches the hardware (e.g. an EC-1000 should have the premium pickups and locking tuners the spec sheet promises).
4. Weight and finish — real LTDs punch above their price in build quality; counterfeit copies feel hollow and cheap.

Value by Serial Number: What's Your LTD Worth?

Your serial number is the starting point for valuation — year and factory drive the second-hand market:

• Korean LTDs (WMI): $200-$800 depending on model and condition. Deluxe-line models (EC-1000, MH-1000) hold value best.
• Indonesian LTDs: $250-$600. 54/7 Series and standard-line models are the budget sweet spot.
• Chinese LTDs: $200-$500. Great value for beginners.

Frequently Asked Questions

How do I read my LTD serial number?

Most LTD serials are printed on the back of the headstock. The prefix identifies the factory — W = Korea (WMI), IW = Indonesia (Wildwood), I = Indonesia (Cort), B/C/D = China — and the following digits encode the production year, month, and unit number. Enter it in the free tool at the top of this page for an instant answer.

How do I use the LTD serial number lookup?

Use the free tool at the top of this page. Enter your serial exactly as printed on the guitar and click Decode to get the production year, factory, and country. No sign-up required.

What is an LTD serial number decoder?

An LTD serial number decoder interprets the characters in your serial number to determine production year, factory location, and country of origin. Our decoder covers LTD Korea (WMI and early Sung-Eum/Unsung), LTD Indonesia (Wildwood and Cort), and LTD China.

Where is the LTD serial number?

On most LTD guitars the serial is on the back of the headstock. Early 1990s models may have it on the neck plate, and some models stamp it inside the control cavity. Check the "Made in" label to confirm the factory matches the prefix.

How do I date an LTD guitar?

Use the prefix to identify the factory, then read the year from the digits: W + YY + MM (Korea), IW + YY + MM (Indonesia Wildwood), I + YY + MM (Indonesia Cort), B/C/D + YY + MM (China). Early Korean formats (E/R/U + year digit) are approximate.

Is there a free LTD serial number checker?

Yes. The tool at the top of this page is a free LTD serial number checker — enter your serial for instant results including production year, factory, and era. No sign-up or payment required.

What's the difference between LTD and ESP serial numbers?

LTD imports use W (Korea), IW/I (Indonesia), or B/C/D (China) prefixes. ESP guitars use E/ES (Japan, late 2015+), factory letters like K/S/T/SS/CH/TH/N (Japan, 2000-2015), US (USA), or pre-2000 numeric headstock and neck plate serials. The prefix immediately tells you the product line and country.

What year is my LTD with a serial starting with W?

The two digits after the W give the year: in W22051234, "22" = 2022, "05" = May. The trailing digits are the production number within that month.

How much is my LTD worth?

Value depends on model line, year, condition, and factory. Korean-built Deluxe models range from $400-$800; Indonesian and Chinese LTDs range from $200-$600. Check our Guitar Price Estimator for a specific range.

Does LTD have an official serial number lookup?

No — ESP/LTD does not offer a comprehensive public serial lookup tool. Our free decoder provides factory identification, production year, and era classification for every LTD factory.
