How to read them
The prefix identifies the plant and the two digits immediately after it give the year. ICS16045678 is Cort Indonesia, 2016. There is no decade guesswork and no reused letters, unlike the Japanese serials.
This makes a modern Squier considerably easier to date accurately than a vintage Fender, which is worth remembering when a listing describes an Indonesian instrument with vague uncertainty about its age.
| Prefix | Plant |
|---|---|
| ICS | Cort, Indonesia |
| IC | Cort, Indonesia |
| IS | Samick, Indonesia |
Examples
- ICS16045678 — Cort Indonesia, 2016
- IC03123456 — Cort Indonesia, 2003
ICS and IC
Both identify Cort's Indonesian operation. Our decoder matches the longer prefix first, so a serial beginning ICS is never read as IC followed by a stray digit — which matters, because misreading the prefix shifts the year digits by one place and produces a date that is wrong but entirely plausible.
ICS12345678 read correctly is 2012. Read as IC followed by S12, it becomes nonsense; read as IC with the S discarded, it becomes 2123 or 1234 depending on where you resume. None of those is obviously wrong on the page, which is exactly why prefix length matters more than it looks.
How Indonesian Squiers fit the range
Indonesia builds across the whole catalogue, from Bullet and Affinity instruments at the entry point to Classic Vibe models that regularly get compared favourably with Mexican-built Fenders costing several times as much.
That spread is worth knowing when reading a listing. The country tells you where it was assembled and nothing about which tier it belongs to — a seller describing an instrument as Indonesian is not describing its quality, and a buyer treating that as a mark against it is filtering out some of the best value Fender currently sells.
Dating one without a readable prefix
Some Indonesian instruments carry serials that have worn or were never fully printed. The potentiometer date codes inside the control cavity are the most reliable fallback: they date the electronics to a week and a year, which brackets the instrument to shortly after.
Failing that, the headstock logo style, the shape of the string tree and the tuner brand all changed on documented dates across the Squier range, and comparing them against catalogue images will usually place an instrument within a couple of years.
What the country tells you
Where an instrument was assembled is a fact about logistics. The Indonesian plants build across the whole Squier range, from entry-level Bullets to Classic Vibe instruments that regularly outperform their price, and the country code predicts very little about how a particular guitar plays.
Common questions
- What does ICS mean on a Squier serial number?
- ICS identifies Cort's Indonesian plant. The two digits immediately after the prefix give the year, so ICS16 is 2016.
