ESP Serial Number Lookup: Decode Your Guitar Instantly
An ESP serial number lookup is the fastest way to identify when and where your guitar was made. ESP has produced guitars in Japan, the USA, Korea, Indonesia, and China since the 1980s — and each factory used different serial formats. Whether you own a hand-built ESP Custom Shop from Tokyo, an ESP USA from North Hollywood, or an LTD import, the serial number holds the key.
Use the free ESP serial number lookup tool above to instantly decode your serial number. It covers ESP Custom Shop (Japan), ESP USA, and LTD imports from Korea, Indonesia, and China — no sign-up required. Enter your number and get production year, factory location, and era in seconds.
At OwningAFender.com, we're the guitar serial number experts — and that expertise extends well beyond Fender. Our free ESP serial number checker covers every major production era and factory.
Part 1: Where Is My ESP Serial Number?
Before you can run an ESP serial number lookup, you need to find the number. ESP and LTD have used several locations over the decades.
Back of Headstock (Most Common): The vast majority of ESP and LTD guitars — especially modern models — have the serial number printed or stamped on the back of the headstock. Look near the top, often in small text below the "ESP" or "LTD" logo. This is the first place to check for any ESP/LTD made after the mid-1990s.
Neck Plate: Some older ESP guitars, particularly 1980s Japanese models and some USA builds, have the serial number stamped on the neck plate — the metal plate where the neck bolts to the body.
Control Cavity: In rare cases, particularly on vintage models or custom builds, 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 ESP Custom Shop guitars, the serial is typically cleanly printed in black ink on the back of the headstock.

Part 2: ESP Custom Shop Japan — Modern Format (2016+)
Since 2016, ESP has used a standardized format for guitars crafted at their Tokyo Custom Shop.
The Format Explained
| Position | Characters | Meaning |
|---|---|---|
| 1 | E or ES | ESP prefix (ES = Original/Standard line) |
| 2-5 | #### | Sequence number |
| 6-7 | YY | 2-digit year |
| 8 | # | Type code |
Type codes:
- 0 = Custom Shop
- 1 = Original Series
- 2 = Signature
- 3 = Standard
Worked Examples
- E3360192: ESP, sequence 3360, 19 = 2019, 2 = Signature → 2019, ESP Custom Shop (Tokyo), Signature model
- ES1234233: ES = Original line, sequence 1234, 23 = 2023, 3 = Standard → 2023, ESP Original Series (Tokyo), Standard
Part 3: ESP Kiso Factory (2000–2015)
The Kiso Factory in Nagano Prefecture, Japan, is ESP's premier manufacturing facility. Guitars made here use a distinct K-prefix format.
The Format Explained
| Position | Characters | Meaning |
|---|---|---|
| 1 | K | Kiso Factory identifier |
| 2-3 | YY | 2-digit year |
| 4-5 | WW | Week of year (01-53) |
| 6 | D | Day of week (1-7) |
| 7-8 | ## | Unit number |
Worked Example
- K0604202: K = Kiso, 06 = 2006, 04 = week 4, 2 = Tuesday, 02 = unit 2 → 2006, Kiso Factory (Nagano), Japan
Part 4: ESP USA (North Hollywood, CA)
ESP USA guitars are built in North Hollywood, California. These are custom instruments with a US prefix.
The Format
US + 5-digit sequential number
Worked Example
- US15432: ESP USA, serial 15432 → ESP USA, North Hollywood, CA
ESP USA serials are approximately sequential, but exact year mapping requires contacting ESP directly. The decoder provides an approximate year range.
Part 5: LTD Korea — World Musical Instruments (WMI)
LTD is ESP's import line. Many higher-end LTD models were made in Korea by World Musical Instruments (WMI).
The Format Explained
| Position | Characters | Meaning |
|---|---|---|
| 1 | W | WMI factory identifier |
| 2-3 | YY | 2-digit year |
| 4-5 | MM | Month (01-12) |
| 6+ | #### | Production number |
Worked Example
- W22051234: W = WMI, 22 = 2022, 05 = May, 1234 = unit → May 2022, World Musical Instruments (WMI), Korea
Part 6: LTD Early Korean Formats (1990s)
Early LTD guitars from the 1990s used single-letter prefixes before standardized numbering.
Format
E, R, or U + year digit (0-9) + 5-digit unit number
| Prefix | Factory | Notes |
|---|---|---|
| E | Sung-Eum (Korea) | Most common early prefix |
| R | Unknown Korean Factory | Less common |
| U | Unsung (Korea) | Also used by Epiphone |
Worked Example
- E712345: E = Sung-Eum, 7 = approximately 1997 → ~1997, Sung-Eum factory, Korea
Part 7: LTD Indonesia
LTD has used two primary factories in Indonesia: P.T. Wildwood and Cort.
Wildwood Format (IW Prefix)
| Position | Characters | Meaning |
|---|---|---|
| 1-2 | IW | Wildwood factory identifier |
| 3-4 | YY | 2-digit year |
| 5-6 | MM | Month (01-12) |
| 7+ | #### | Production number |
Example: IW22051234 = 2022, May, Wildwood Indonesia
Cort Format (I Prefix)
| Position | Characters | Meaning |
|---|---|---|
| 1 | I | Cort Indonesia identifier |
| 2-3 | YY | 2-digit year |
| 4-5 | MM | Month (01-12) |
| 6-10 | ##### | Production number |
Example: I220512345 = 2022, May, Cort Indonesia
Part 8: LTD China
LTD guitars made in China use single-letter factory codes.
The Format
| Position | Characters | Meaning |
|---|---|---|
| 1 | B, C, or D | Factory code |
| 2-3 | YY | 2-digit year |
| 4-5 | MM | Month (01-12) |
| 6+ | #### | Production number |
| Code | Factory |
|---|---|
| B | LTD China (Factory B) |
| C | LTD China (Factory C) |
| D | LTD China (Factory D) |
Worked Example
- B22051234: B = Factory B, 22 = 2022, 05 = May → May 2022, LTD China (Factory B)
Part 9: Vintage ESP — 1980s Neck Plate Serials
Early ESP guitars from the 1980s used 5-digit sequential numbers stamped on the neck plate.
Format
5-digit numeric serial (e.g., 12345, 56789)
These are approximately sequential starting around 5000 in the mid-1980s. Exact dating is difficult without factory records, but the decoder provides an approximate year range based on known reference points.
Example: 67890 = approximately late 1980s, Tokyo, Japan
Serial Prefix Quick Reference
Complete reference table for all ESP/LTD serial number prefixes:
| Prefix | Year Range | Country | Factory | Notes |
|---|---|---|---|---|
| E/ES + digits | 2016+ | Japan | ESP Custom Shop (Tokyo) | Modern ESP Japan format |
| K + digits | 2000-2015 | Japan | ESP Kiso Factory (Nagano) | Premier manufacturing facility |
| US + 5 digits | 2000s+ | USA | ESP USA (North Hollywood) | Custom shop USA builds |

| 5-digit numeric | 1985-1995 | Japan | ESP (Tokyo) | Neck plate serials |
How to Read Your ESP Serial Number: Step-by-Step
Follow this process to decode any ESP or LTD from the 1980s onward.
- Locate the serial number on the back of the headstock (most common), neck plate (vintage), or inside the control cavity.
- Check for letter prefixes. E/ES = modern Japan Custom Shop. K = Kiso Factory. W = Korea WMI. IW = Indonesia Wildwood. I = Indonesia Cort. B/C/D = China. US = USA.
- For E/ES prefix: YY digits = year, type code = model line (0=Custom Shop, 1=Original, 2=Signature, 3=Standard).
- For K prefix: YY = year, WW = week, D = day of week.
- For W prefix: YY = year, MM = month, remainder = production number.
- For 5-digit numeric only: Likely 1980s Japanese neck plate serial. Approximate dating only.
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.
ESP vs LTD: Understanding the Relationship
Many guitar owners wonder about the relationship between ESP and LTD. Understanding this helps you interpret your serial number correctly.
ESP is the premium brand. ESP guitars are made in Japan (Custom Shop, Kiso Factory) or the USA (North Hollywood). They command premium prices ($1,500-$5,000+) and are built for professional players.
LTD is the affordable line. LTD guitars are made in Korea, Indonesia, and China. They offer ESP designs at more accessible prices ($300-$1,200). The LTD Deluxe and LTD Elite lines blur this boundary with higher-end specs.
Different serial systems. ESP Japan uses E/ES and K prefixes. ESP USA uses US prefixes. LTD imports use W, IW, I, B/C/D, and early E/R/U prefixes. The serial prefix immediately tells you which line and country your guitar comes from.
Quality tiers. ESP Custom Shop = highest tier. ESP Original / Standard = premium production. LTD Deluxe = mid-high tier. LTD Standard = entry to mid tier.
Just Got a Used ESP or LTD?
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:
- Check Action Height — Learn the correct action for your playing style
- Adjust Truss Rod — Dial in the right neck relief
- Choose the Right Strings — String gauge affects tone and playability
- Check Factory Specs — Find the exact specs for your model
- Add to My Garage — Track your guitar's setup history
What's Your ESP/LTD Worth?
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 ESP/LTD value:
- Model line — ESP Custom Shop > ESP Original > LTD Deluxe > LTD Standard
- Country of origin — Japan > USA > Korea > Indonesia > China for collectibility
- Condition — All-original parts and clean finish add significant value
- Signature models — Artist signature ESPs often hold value better
- Vintage ESP — 1980s Japanese ESPs are increasingly collectible
If you're selling or just want your guitar playing its best, a proper setup is the highest-ROI improvement you can make.
Recommended Strings for Your ESP/LTD
Now that you've identified your ESP/LTD's production year and factory, choose strings that match its era and model. ESP and LTD guitars typically use standard scale lengths, so string selection follows familiar principles:
For ESP/LTD with humbuckers (most models): 10-46 is the factory standard. For heavier styles, 11-48 or 12-52 provide fuller tone and better tuning stability.
For ESP/LTD with Floyd Rose tremolos: Consider a slightly heavier bottom end (10-52 hybrid) to maintain tuning stability under heavy tremolo use.
For LTD entry-level models: Quality strings can transform these guitars. Upgrade from factory strings to premium nickel-plated steel for immediate improvement.
Buy on AmazonEssential Maintenance for Your ESP/LTD
ESP and LTD guitars are built for performance, and proper maintenance keeps them playing their best. After identifying your guitar, consider these maintenance essentials:
String care: Fresh strings with regular cleaning extend playability and tone significantly. ESP/LTD guitars with Floyd Rose bridges especially benefit from fresh strings.
Floyd Rose bridges: Many ESP models feature Floyd Rose trems. Keep the knife edges lubricated, check saddle intonation, and ensure the locking nut clamps securely.
Pickup height: ESP pickups benefit from proper height adjustment. Active EMG pickups (common on ESP) have different optimal heights than passive pickups.
Hardware upgrades: Many LTD players upgrade tuners and bridges. Quality upgrades on a well-maintained LTD can rival guitars costing twice as much.
Authentication Tips: Spotting Fake ESP/LTD Guitars
Serial numbers are your first line of defense against counterfeits. Fake ESPs and LTDs are common, especially for popular models.
Red flags:
- Format doesn't match the claimed origin. An ESP labeled "Made in Japan" should have E/ES or K prefix. An LTD labeled "Made in Korea" should have a W prefix. An LTD labeled "Made in Indonesia" should have IW or I prefix.
- Serial length is wrong. Modern ESP E-prefix serials are 8 digits. K-prefix is 8 digits. W-prefix is 10+ digits. If yours is significantly shorter or longer, verify carefully.
- Font and printing quality. Genuine ESP/LTD serials are cleanly printed. Blurry, smudged, or poorly aligned text is suspicious.
- Physical features don't match the era. A serial suggesting 2020 production but with hardware and specs from a different era is concerning.
Verification steps:
- Run the serial through our decoder above. Does the result match the guitar's apparent age and features?
- Check the "Made in" label. Does the country match the serial prefix?
- Compare logo style, tuners, and hardware to known examples from that year on ESP's official site or Reverb listings.
- For high-value models (ESP Custom Shop, signature models), consider contacting ESP directly for verification.
Serial Number Mysteries Solved: Real Case Studies
Case Study 1: The "Is This a Real Custom Shop?" Horizon
The Mystery: An ESP Horizon with serial E3360192. The owner bought it used and wasn't sure if it was a genuine Custom Shop guitar.
The Investigation: The E prefix with 8-digit format indicates 2016+ ESP Custom Shop (Tokyo). The "3" in position 3-6 is the sequence, "19" = 2019, "2" = Signature model line.
The Solution: This was a legitimate 2019 ESP from the Tokyo Custom Shop, Signature series. The owner confirmed the features matched the signature model specs.
Takeaway: The E/ES format is reliable for verifying modern ESP Japan guitars.
Case Study 2: The Budget Find with a K Prefix
The Mystery: A guitar listed as "ESP LTD" with serial K0604202. The buyer was confused because K-prefix guitars command higher prices.
The Investigation: The K prefix indicates the ESP Kiso Factory in Nagano, Japan — not an LTD import. Kiso Factory guitars are premium ESP instruments, not LTD budget models.
The Solution: The guitar was a genuine 2006 ESP Kiso Factory build, worth significantly more than a comparable LTD. The seller had mislabeled it.
Takeaway: K-prefix = ESP Japan (premium), not LTD. Always verify the prefix before pricing.
Case Study 3: The Ambiguous LTD Origin
The Mystery: An LTD EC-1000 with serial B22051234. The owner couldn't determine if it was Chinese or Korean production.
The Investigation: The B prefix indicates LTD China (Factory B). The "22" = 2022, "05" = May. Korean LTDs use the W prefix (WMI).
The Solution: This was a 2022 LTD EC-1000 made in China. The EC-1000 has been produced in both Korea and China over the years — the prefix is the definitive indicator.
Takeaway: B/C/D = China. W = Korea. IW/I = Indonesia. The prefix is definitive for LTD origin.
Value by Serial Number: What's Your ESP/LTD Worth?
Serial number dating is the first step to valuing your ESP or LTD. Once you know the year and factory, you can estimate market value.
ESP Japan (1980s–Present)
Japanese ESPs command the highest prices in the used market.

- Kiso Factory (K prefix, 2000-2015): $1,000-$3,000+
- Custom Shop (E/ES prefix, 2016+): $1,500-$5,000+
- Key models: Horizon, M-Series, Eclipse, Snapper
- Value factor: All-original examples with cases command premium prices
ESP USA (2000s–Present)
ESP USA guitars are custom-built and relatively rare.
- ESP USA (US prefix): $2,000-$5,000+
- Key models: USA Horizon, USA M-II, USA Eclipse
- Value factor: Limited production runs and custom options add value
LTD Korea (1990s–Present)
Korean LTDs offer excellent value and solid build quality.
- WMI factory (W prefix): $300-$800
- Early Korean (E/R/U prefix, 1990s): $200-$500
- Key models: EC-1000, MH-1000, H-1001
- Value factor: Early 2000s Korean LTDs are well-regarded for build quality
LTD Indonesia (2000s–Present)
Indonesian LTDs are the most common modern imports.
- Wildwood (IW prefix) / Cort (I prefix): $250-$600
- Key models: EC-256, MH-200, M-200
- Value factor: LTD Deluxe models hold value better than Standard models
LTD China (2000s–Present)
Chinese LTDs are entry-level imports.
- Factory B/C/D: $200-$500
- Key models: EC-10, EC-50, M-10
- Value factor: These are budget guitars; condition matters more than age
Factors That Affect ESP/LTD Value
Condition is the most important factor. Mint examples command 20-30% premiums over "good" condition.
Model line matters significantly. ESP Custom Shop > ESP Original > LTD Deluxe > LTD Standard.
Country of origin affects collectibility. Japan > USA > Korea > Indonesia > China for collector value.
Originality matters for Japanese and USA models. Original pickups, hardware, and finish add value.
Signature models often hold value better due to artist association and limited production.
Troubleshooting Guide
Can't Find Your Serial Number
Check all common locations: back of headstock first, then neck plate (vintage models), then inside the control cavity. Use good lighting and a magnifying glass. Serial numbers can be small and faint, especially on older guitars.
Serial Number Is Worn or Faded
Modern ESP 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.
Serial Doesn't Match Any Format
ESP/LTD 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 custom shop one-offs may not follow standard formats.
Is My LTD an ESP?
LTD is ESP's import brand, but they are distinct product lines. An LTD will say "LTD" on the headstock and use import prefixes (W, IW, I, B/C/D, or early E/R/U). An ESP will say "ESP" on the headstock and use Japanese or USA prefixes (E/ES, K, US, or vintage 5-digit).

What's the difference between ESP and LTD serial numbers?
ESP guitars use Japanese or USA prefixes: E/ES (Custom Shop Tokyo), K (Kiso Factory), US (USA), or 5-digit neck plates (1980s). LTD imports use W (Korea), IW/I (Indonesia), or B/C/D (China). The prefix immediately tells you the product line and country.
Are Japanese ESPs better than LTD imports?
Japanese ESPs are hand-crafted in Tokyo or Kiso with premium materials and hardware. LTD imports offer ESP designs at more accessible prices with solid construction. For professional use, ESP Japan is the top tier. For hobbyists and intermediate players, LTD Deluxe and above offer excellent value.
How much is my ESP/LTD worth?
Value depends on model line, year, condition, and country. Japanese ESPs range from $800-$5,000+. ESP USA models range from $2,000-$5,000+. Korean LTDs range from $200-$800. Indonesian LTDs range from $250-$600. Chinese LTDs range from $200-$500.
What year is my ESP with serial starting with E?
The two digits after the sequence number indicate the year. In E3360192, "19" = 2019. In ES1234233, "23" = 2023. The first digit after the year is the type code (0=Custom Shop, 1=Original, 2=Signature, 3=Standard).
Are old ESP guitars worth anything?
Yes. Vintage ESP guitars from the 1980s with neck plate serials are increasingly collectible and can sell for $800-$2,500+. Early 1990s Korean LTDs also have moderate collectibility among players who appreciate that era's build quality.
How do I tell if my ESP/LTD is real?
Check that the serial format matches the "Made in" label (E/ES/K = Japan, US = USA, W = Korea, IW/I = Indonesia, B/C/D = China). Verify the headstock logo, hardware, and pickups match the claimed model. Compare to official ESP product photos. For high-value models, contact ESP directly.
What is the difference between ESP Original and Custom Shop?
ESP Original Series is the premium production line from the Tokyo factory. ESP Custom Shop is the bespoke, made-to-order line. Both use E/ES prefixes, but the type code distinguishes them (0 = Custom Shop, 1 = Original).
Does ESP have an official serial number lookup?
ESP does not offer a comprehensive public serial lookup tool. Our decoder provides detailed results including factory identification, year of production, and era classification — all for free.
