Squier Precision Bass Serial Numbers: Dating & Identification Guide

Squier Precision Bass Serial Numbers Explained

Squier Precision Bass serial numbers are the fastest way to turn a stamped or printed code into the year, factory, and series of your P Bass. Whether you are buying a used Affinity, selling a vintage Japanese Squier, or just curious about the instrument in your hands, the serial number is the first clue to unlock.

Squier has built Precision Basses in Japan, Korea, Mexico, China, Indonesia, and India since the early 1980s. Each factory used its own prefix system, and some prefixes overlap between countries, which makes a quick visual check unreliable. The easiest first step is to run the number through the Squier serial number lookup tool. This guide explains what the decoder is telling you, where to find the serial, and how to avoid the most common dating mistakes.

What a Squier Precision Bass Serial Number Tells You

A serial number is not a certificate of authenticity by itself, but it usually reveals:

• Production year — the calendar year the bass left the factory
• Manufacturing country — Japan, Korea, Mexico, China, Indonesia, or India
• Factory or series — Fuji-Gen, Dyna Gakki, Samick, Cort, and others
• Product tier — entry-level Affinity, mid-range Classic Vibe, or vintage-reissue Vintage Modified

It does not prove originality on its own. Necks and bodies get swapped, decals get reprinted, and parts-basses are common in the budget market. Treat the serial as the first filter, then back it up with physical inspection. For high-value or suspicious instruments, pair the serial check with the Fender fake checker.

Where to Find the Serial Number on a Squier Precision Bass

Most Squier Precision Basses carry their serial number on the back of the headstock, but the exact location and format depend on the era and factory. Check all the likely places before deciding the number is missing.

Headstock Back (Most Common)

Modern Squier Precision Basses from Indonesia, China, and India print the serial on the back of the headstock. Look for a black or silver decal near the bottom edge. Typical examples include IC210123456, CY210123456, CC210123456, or CSI210123456.

Neck Plate (Vintage and Some Reissues)

Some 1980s and 1990s Squier Precision Basses stamp the serial on the metal neck plate between the neck and body. You can see it without removing anything by looking at the back of the bass where the neck bolts on. Early Japanese Squiers sometimes used the neck plate as the only serial location.

Headstock Front (Early Japanese Models)

Some 1980s Japanese Squiers placed a small sticker or stamped number on the front of the headstock, usually near the Squier logo. These are often shorter numbers, sometimes five or six digits with a prefix.

Neck Heel and Body Cavity

Some Japanese and higher-end Squiers 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. Good side-lighting helps faint stamps read clearly, and the photo is useful for insurance, resale, and future setup notes.

Decoding Squier Precision Bass Serial Numbers by Era

Squier Precision Bass serials fall into clear eras. Because the P Bass is one of Fender's oldest designs, the Squier version has been made continuously since 1982, and the numbering systems track the brand's global factory moves.

Japanese JV and SQ Series (1982–1984)

The first Squiers were made by Fuji-Gen in Japan and carried JV or SQ prefixes. JV Squiers from 1982–1984 are especially sought after. A genuine JV serial reads JV0xxxxx for 1982, JV1xxxxx for 1983, and JV2xxxxx for 1984. SQ serials followed in 1983–1984. See the Fender JV/SQ serial guide for full details.

Japanese E-Series (1984–1987)

After the JV/SQ era, Fuji-Gen continued with E prefixes. A Japanese E4 bass is a 1984 Fuji-Gen Squier, not a 1984 US Fender. These overlap with US E-series numbers, so always check the "Made in Japan" or "Crafted in Japan" text on the headstock. See the Fender E-Series serial guide for more.

Japanese A, B, and C Series (1980s)

Fuji-Gen used single-letter prefixes A, B, and C in the mid-to-late 1980s. These are less common than E-series instruments but still appear in the used market. The same prefix letter rules apply: check the country of manufacture before assigning a value.

Crafted in Japan and Made in Japan (1990s–2000s)

Around 1997 the "Made in Japan" decal changed to "Crafted in Japan." Serials became longer numeric codes, often with a leading prefix letter indicating the factory. These basses are still well regarded and can out-value modern imports. Modern Fender Japan models use different numbering, so use the Squier serial number decoder for anything built after 2015.

Korean Squier Precision Bass Serials (1980s–1990s)

Korean-made Squiers from the late 1980s and 1990s used prefixes like E, S, M, and K. These are less common than Japanese or Indonesian instruments but still appear in the used market. Korean Squiers were often built by Samick or Cort and represent solid mid-range quality for the era.

Mexican Squier Precision Bass Serials (1990s)

Some 1990s Squiers were made in Mexico and carry MN or MZ prefixes, similar to Fender Mexico. The digits after the prefix indicate the year. MN10 12345 would be 1990, while MZ15 12345 would be 1995. For a deeper dive, see the Fender MN/MZ serial guide.

Chinese Squier Precision Bass Serials (1990s–present)

China-made Squiers use prefixes like CY, CA, CC, and CN. These are entry-level instruments aimed at beginners and are priced accordingly. A genuine Chinese Squier is a legitimate beginner bass, but it is not a vintage Japanese model — check the prefix before paying a premium.

Indonesian Squier Precision Bass Serials (2000s–present)

Modern Squier Classic Vibe, Contemporary, Affinity, and Bullet Precision Basses often come from Indonesia. Look for IC, IS, or CIS prefixes. The year is encoded in the digits after the factory code. For example, IC21xxxxxx usually indicates a 2021 Indonesian Squier.

Indian Squier Precision Bass Serials

A smaller number of Squiers have been built in India. These typically carry S or other regional prefixes and are less common in North American and European markets. If you see an unfamiliar prefix, the Squier serial number lookup is the safest way to confirm the origin.

What to Do After You Decode Your Squier P Bass

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 so you know whether a listing is fair before you make an offer.

If you are selling, use the value estimate to set a realistic price. A "2019 Squier Classic Vibe '60s Precision Bass" will sell faster and for more than a vague "used Squier bass."

Verify Authenticity

Serial decoding is step one. Step two is checking that the bass matches the serial. Red flags include:

• A 1980s-style logo on a bass with a 2020s serial
• Modern tuners on a vintage-era serial
• A neck-plate serial that conflicts with the headstock serial
• Missing or reprinted decals

For a structured red-flag checklist, use the free Fender fake checker.

Set It Up for the Correct Era and Style

A 1984 Japanese Squier Precision Bass needs different setup expectations than a 2024 Contemporary Active P Bass. 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, and the bass setup guide covers P Bass-specific specs.

A good starting point for a modern Squier Precision Bass 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 2.0 mm (5/64 inch) on the G string and 2.4 mm (3/32 inch) on the E string
• 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

Common Squier Precision Bass Serial Number Mistakes

Buyers and sellers make the same errors repeatedly. Avoiding these will save you money and embarrassment.

Confusing Fender and Squier Prefixes

A US E4 serial means a 1984 American Fender. A Japanese E4 serial on a Squier means a 1984 Fuji-Gen Squier. The same prefix in two different brands represents two very different values. Always check the logo and the "Made in..." text on the headstock or the decoder's country field.

Assuming Lower Serial Numbers Are Always Better

A low serial does not automatically make a bass more valuable. A 1995 Korean Squier P Bass with serial S9 000123 is still a 1995 Korean Squier. The year, condition, and originality matter far more than the specific number within that year.

Trusting the Decal Over the Serial

Decals are easy to reprint. A headstock can say "Vintage Modified" while the serial points to a 2010 Indonesian Standard. If the serial and the decal disagree, believe the serial and investigate further.

Treating All Squier Serials as Interchangeable

Squier has used many numbering systems across many countries. Modern Indonesian Squiers use IC, IS, and CIS prefixes that never appeared on 1980s Japanese Squiers. Use the Squier serial number lookup for any guitar with a Squier decal rather than guessing based on a Fender chart.

Frequently Asked Questions

How do I read a Squier Precision Bass serial number?

Locate the serial on the back of the headstock, neck plate, or headstock front. Note the full prefix and digits, then enter them into the Squier serial number decoder. The prefix letters tell you the factory and decade, while the digits usually reveal the year.

Where is the serial number on a Squier Precision Bass?

Most Squier Precision Basses have the serial on the back of the headstock. Vintage Japanese models may use the neck plate or the front of the headstock. Some higher-end Squiers also stamp a secondary number inside the neck pocket or on the neck heel.

What does an IC serial number mean on a Squier P Bass?

IC means the bass was made in Indonesia. The digits after IC usually indicate the year. For example, IC210123456 is typically a 2021 Indonesian Squier Precision Bass.

What does a CY serial number mean on a Squier P Bass?

CY means the bass was made in China. These are usually entry-level instruments such as Affinity or Bullet series. The digits after CY encode the year of manufacture.

Are Japanese Squier Precision Bass serial numbers different?

Yes. Japanese Squier Precision Basses use their own prefixes, including JV, SQ, E, A, B, and C in the 1980s, and longer numeric serials in the "Crafted in Japan" era. Modern Japan models use different numbering best read with the decoder.

Can a Squier Precision Bass 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 bass'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 P Bass is Japanese or Indonesian?

The prefix is the quickest clue. Japanese guitars typically use JV, SQ, E, A, B, C, or longer numeric MIJ/CIJ serials. Indonesian guitars use IC, IS, or CIS. The decoder also returns the country directly.

What year is my Squier Precision Bass by serial number?

Enter the serial into the Squier serial number lookup. For most basses it returns the exact production year. For ambiguous or transitional serials, the decoder will flag the likely range.

Does the serial number affect Squier Precision Bass value?

Indirectly. The serial identifies the year and factory, which are two major value drivers. Condition, originality, and market demand then refine the price. Use the Guitar Price Estimate for a current market range.

Why does my Squier Precision Bass have two serial numbers?

Some basses carry a headstock serial and a separate neck-plate or neck-heel stamp. This is normal for vintage Japanese and higher-end instruments. If the two numbers conflict, the bass may have had a replacement neck or body.
