Squier Mustang Serial Numbers: Dating & Identification Guide
Learn how to read Squier Mustang serial numbers to date your guitar by year, factory, and country. Covers Bullet Mustang serial, Classic Vibe Mustang serial, Vintage Modified Mustang serial, and more.
Squier Mustang Serial Numbers Explained
Squier Mustang serial numbers are the fastest way to turn a stamped or printed code into the year, factory, and country of your short-scale offset. Whether you are buying a used Bullet Mustang, selling a Classic Vibe, or just curious about your Vintage Modified, the serial number is the first clue to decode.
Squier has built Mustangs in Japan, Korea, China, Indonesia, and Vietnam since the 1980s, and each factory used its own prefix format. Modern Squier Mustangs almost always carry a factory code plus a two-digit year. Run the number through the Squier serial number lookup tool, then use this guide to understand what the decoder is telling you.

What a Squier Mustang Serial Number Tells You
A serial number is not a birth certificate, but it usually reveals:
- Production year — the calendar year the guitar left the factory
- Manufacturing country — Indonesia, China, Korea, Japan, or Vietnam
- Factory or contractor — Cort, Samick, Yako, and others
- Series or era — Bullet, Classic Vibe, Vintage Modified, Contemporary, Sonic, or Affinity
It does not prove originality on its own. Necks and bodies get swapped, decals get reprinted, and counterfeit Squiers are common. Treat the serial as the first filter, then back it up with physical inspection or the Squier fake checker.
Where to Find the Serial Number on a Squier Mustang
The exact serial location depends on the year and country of manufacture. Check all the likely places before deciding the number is missing.
Headstock Back (Most Common Today)
Modern Indonesian and Chinese Squier Mustangs carry the serial on the back of the headstock, usually as black or silver print near the bottom edge. Typical examples include ICS19xxxxxx, CY20xxxxxx, CC210123456, or CGS21xxxxxx.
Neck Plate (Older Korean and Japanese Models)
Some 1980s and 1990s Squier Mustangs stamp the serial on the metal neck plate. You can see it where the neck bolts onto the body without removing anything.
Neck Heel and Body Cavity
Some Japanese and vintage-style reissues add a secondary stamp inside the neck pocket or on the heel of the neck. You may need to loosen the neck bolts to see it. These internal numbers can confirm the headstock number or reveal a replacement neck.
Pro Tip: Photograph Before You Decode
Snap a clear photo of the serial before you start searching. Side-lighting helps faint stamps read clearly, and the photo is useful for insurance, resale, and setup notes.
How to Read Modern Squier Mustang Serial Numbers
Modern Squier Mustang serials follow a simple pattern: factory prefix, two-digit year, and production sequence.
Indonesia Squier Mustang Serial Numbers
Indonesia is the most common source for current Squier Mustangs. The main prefixes are:
| Prefix | Factory / Meaning |
|---|---|
| IC | Indonesia Cort |
| ICS | Indonesia Cort, Squier |
| ISS | Indonesia Samick, Squier |
| CIS | Indonesia (Cort, later production) |
An ICS19xxxxxx serial is a 2019 Indonesian Squier Mustang made by Cort. The decoder returns the exact factory and year, but the prefix alone gets you most of the way there.
China Squier Mustang Serial Numbers
China builds many entry-level and Classic Vibe Squier Mustangs. Common prefixes:
| Prefix | Factory / Meaning |
|---|---|
| CY | China Yako |
| CC | China Classic Vibe |
| CGS | China Grand Reward / other contractor |
| COB | China OEM / various contractors |
A CY20xxxxxx serial is a 2020 China-made Squier Mustang from Yako. If a listing says "Classic Vibe" but the serial starts with CY or CGS, verify carefully — Classic Vibe Mustangs usually use CC prefixes.
Korea Squier Mustang Serial Numbers
Korean-made Squier Mustangs from the late 1980s and 1990s used prefixes like E, S, and K. These are less common today but still appear in the used market.
Japan Squier Mustang Serial Numbers
Japan-made Squier Mustangs are the most collectable. The first Squiers were made by Fuji-Gen in Japan and carried JV or SQ prefixes. A genuine JV serial reads JV0xxxxx for 1982, JV1xxxxx for 1983, and JV2xxxxx for 1984.
Fender Japan also used E, A, B, and C prefixes in the mid-to-late 1980s. These overlap with US prefixes, so a Japanese E4 guitar is not the same as a US E4. Always cross-check the country label. Around 1997 the "Made in Japan" decal changed to "Crafted in Japan," with nine- or ten-digit serials where the leading digits indicate the year.
Bullet Mustang Serial Numbers
The Bullet Mustang is Squier's popular short-scale model with a 24-inch scale and a hardtail bridge. Bullet Mustangs have been made in Indonesia and China.
Common Bullet Mustang Serial Formats
| Era | Typical Prefix | Example |
|---|---|---|
| 2016–2019 | CY (China Yako) | CY16xxxxxx |
| 2019–2023 | ICS (Indonesia Cort) | ICS19xxxxxx |
| 2023–present | CC / CGS (China) | CC2301xxxx |
A Bullet Mustang serial starting with CY17 is a 2017 China-made guitar. An ICS21 serial is a 2021 Indonesia-made guitar. Because the Bullet series has moved between factories, the prefix is the only reliable way to know the country of origin. The Squier serial number lookup will resolve these quickly.
Bullet Mustang Dating Tips
Bullet Mustangs were introduced in 2016, so any earlier serial is either misread or not a Bullet Mustang. The body is thinner than a Classic Vibe, the tuners are sealed die-cast, and the bridge is a six-saddle hardtail.
Classic Vibe Mustang Serial Numbers
The Classic Vibe Mustang is Squier's vintage-correct tier with a 24-inch scale, offset body, vintage-style tremolo, and Alnico pickups. It has been made in Indonesia and China.
Common Classic Vibe Mustang Serial Formats
| Era | Typical Prefix | Example |
|---|---|---|
| 2013–2019 | ICS (Indonesia Cort) | ICS15xxxxxx |
| 2019–2023 | IC / ICS (Indonesia) | IC19xxxxxx |
| 2023–present | CC / CGS (China) | CC2301xxxx |
Classic Vibe Mustangs carry a premium, so sellers sometimes swap a Classic Vibe decal onto a cheaper guitar. A "Classic Vibe" with a CY or CGS serial deserves extra scrutiny.
Classic Vibe Hardware Clues
A genuine Classic Vibe should have vintage-style tuners, Alnico pickups, and a vintage tremolo. Ceramic pickups, sealed tuners, and a hardtail bridge suggest a Bullet or Affinity with a swapped decal.
Vintage Modified Mustang Serial Numbers
The Vintage Modified Mustang was Squier's mid-tier vintage-style offset, produced roughly 2012 to 2019, mostly in Indonesia.
Common Vintage Modified Mustang Serial Formats
| Era | Typical Prefix | Example |
|---|---|---|
| 2012–2016 | ICS (Indonesia Cort) | ICS13xxxxxx |
| 2016–2019 | IC / ICS (Indonesia) | IC17xxxxxx |
A Vintage Modified serial starting with ICS14 is a 2014 Indonesia-made guitar. These models are out of production, so used prices can be soft. If a seller calls a guitar "Vintage Modified" but the serial starts with CY or CC, verify the specs.
Other Squier Mustang Series
Beyond Bullet, Classic Vibe, and Vintage Modified, Squier has released several other Mustang-related models.
Squier Sonic Mustang
The Squier Sonic Mustang replaced the Bullet Mustang in some markets in 2023. It is the entry-level short-scale option with a thinner body, ceramic pickups, and basic hardware. Serials follow the same ICS/CC/CGS patterns. A CC23xxxxxx serial is a 2023 China-made Sonic Mustang.
Squier Contemporary Mustang
The Contemporary Mustang is the modern-spec version with humbuckers, a flatter fingerboard radius, and often a hardtail bridge. Serials typically use ICS or IC prefixes.
Squier Affinity Mustang
The Affinity Mustang sits between Sonic and Classic Vibe. It has been made in Indonesia with IC or ICS prefixes. Affinity Mustangs share the thinner Affinity body profile with other Affinity models.
Common Squier Mustang Serial Mistakes
Avoid these common mistakes to save money and embarrassment.
Confusing Country Prefixes
A CY serial means China Yako. An ICS serial means Indonesia Cort. A CC serial means China Classic Vibe. Always match the prefix to the "Made in..." label on the headstock front.
Assuming All Short-Scale Squiers Are Mustangs
Squier also makes short-scale Jaguars, Jazzmasters, and Duo-Sonics. The body shape tells you the model; the serial only tells you where and when it was made.
Trusting the Decal Over the Serial
Decals are easy to reprint. A headstock can say "Classic Vibe" while the serial points to a 2017 Bullet Mustang. If the serial and decal disagree, believe the serial and investigate further with the Squier fake checker.
Treating Squier Serials Like Fender Serials
Squier uses IC, CY, CC, CGS, ICS, and ISS prefixes that never appear on USA Fenders. Use the Squier serial number lookup for Squier-branded guitars and the Fender serial number lookup for Fender-branded Mustangs.
What to Do After You Decode Your Squier Mustang
Once the serial tells you the year and country, the next logical steps are value, authenticity, and setup.
Check the Market Value
A serial decode gives you the baseline era. For an actual market range, plug the details into the Guitar Price Estimate. It weights year, model, condition, and current demand. If you are selling, a "2019 Classic Vibe Mustang" will sell faster than a vague "used Mustang."
Verify Authenticity
Serial decoding is step one. Step two is checking that the guitar matches. Red flags include a "Classic Vibe" decal on a Bullet-era serial, modern tuners on a vintage-era serial, or a serial country that does not match the "Made in..." label. Use the free Squier fake checker for a structured checklist.
Set It Up for the Correct Series
A Bullet Mustang needs different setup expectations than a Classic Vibe. Neck profiles, fretboard radius, bridge type, and pickup output all affect the ideal action and pickup height. The Squier setup guide walks through the measurements step by step.
A good starting point for a modern Squier Mustang is:
- Neck relief: roughly 0.010 inches at the 7th fret with the string held at the 1st and last frets
- Action at the 12th fret: about 1.6 mm (1/16 inch) on the high E and 2.0 mm (5/64 inch) on the low E
- Pickup height: around 2.4 mm (3/32 inch) on the bass side and 2.0 mm (5/64 inch) on the treble side, measured from the pole piece to the bottom of the string with the string held at the last fret
If you own a Strat-style Squier too, the Squier Stratocaster setup guide has series-specific specs for Sonic, Affinity, and Classic Vibe. Tele-style Squier owners can use the Squier Telecaster setup guide.
Frequently Asked Questions
How do I read a Squier Mustang serial number?
Locate the serial on the back of the headstock, neck plate, or neck heel. Note the full prefix and digits, then enter them into the Squier serial number lookup. The prefix letters tell you the factory and country, while the digits usually reveal the year.
Where is the serial number on a Squier Mustang?
Most modern Squier Mustangs have the serial on the back of the headstock. Older Korean and Japanese models may use the neck plate. Some Japanese and vintage-style reissues also stamp a secondary number inside the neck pocket or on the neck heel.
What does an ICS serial number mean on a Squier Mustang?
ICS means Indonesia Cort, Squier. The digits after the prefix include the year. For example, ICS19xxxxxx is a 2019 Indonesian Squier Mustang made by the Cort factory.
What does a CY serial number mean on a Squier Mustang?
CY means China Yako. The digits after CY indicate the year. For example, CY20xxxxxx is a 2020 China-made Squier Mustang from the Yako factory.
How do I date a Bullet Mustang?
Bullet Mustangs were introduced in 2016. Common serial prefixes include CY for China and ICS for Indonesia. A CY17xxxxxx serial is a 2017 China-made Bullet Mustang; an ICS21xxxxxx serial is a 2021 Indonesia-made Bullet Mustang.
How do I date a Classic Vibe Mustang?
Classic Vibe Mustangs have used ICS, IC, and CC prefixes depending on the era and factory. An ICS15xxxxxx serial is a 2015 Indonesia-made Classic Vibe Mustang; a CC2301xxxx serial is a 2023 China-made Classic Vibe Mustang.
What is the difference between Vintage Modified and Classic Vibe Mustang serials?
Vintage Modified Mustangs were produced mostly from 2012 to 2019 and primarily used ICS and IC prefixes from Indonesia. Classic Vibe Mustangs overlap with those prefixes in some years, so the serial alone may not separate the two series — check the hardware and model name as well.
Can a Squier Mustang serial number be fake?
Yes. Decals and stamps can be reproduced. A fake serial may decode to a year or factory that does not match the guitar's hardware, logo, or wear. Always cross-check the serial against the physical features and use an authenticity checklist for expensive guitars.
How do I know if my Squier Mustang is Indonesian or Chinese?
The prefix is the quickest clue. Indonesian Squier Mustangs typically use IC, ICS, or ISS. Chinese Squier Mustangs typically use CY, CC, CGS, or COB. The decoder also returns the country directly.
Does the serial number affect Squier Mustang value?
Indirectly. The serial identifies the year, factory, and sometimes the series, which are major value drivers. Condition, originality, and market demand then refine the price. Use the Guitar Price Estimate for a current market range.
