Gretsch

Gretsch serial numbering split into three distinct eras. Pre-1966 numbers were largely sequential. From 1966 to the end of Baldwin-era production (1972-ish) Gretsch used a date-coded format that packs the month, year, and production rank into a short numeric. Modern production (2003+) uses a clean two-letter factory code followed by YY + MM + a 4-digit sequence.

JT + 8 digits Modern (2003+) — factory + YY + MM + seq primary e.g. JT07115922 2003+
6 digits Date-coded (1966–1972) primary e.g. 118145 1966–1972
5 digits Pre-1966 sequential (1939–1965) e.g. 45000 1939–1965

Supported formats

Modern (2003+) — factory + YY + MM + seq

2003+

Example JT07115922 Try it →

Two-letter factory code + 2-digit year + 2-digit month + 4-digit sequence. Factory codes: JT = Japan Terada (most common), JD = Japan Dyna Gakki, JF = Japan Fuji-Gen Gakki, KP = Korea Peerless, KS = Korea Samick/SPG, CY = China Yako, CS = USA Custom Shop. Example JT07115922 = Japan Terada, November 2007, #5922.

Date-coded (1966–1972)

1966–1972

Example 118145 Try it →

First digit(s) are the numerical month (1-12), next digit is the last digit of the year (7, 8, 9 for 1967–1969 and 0, 1, 2 for 1970–1972), remaining digits are the production rank. Example 118145 = November (11) 1968 (8), #145.

Gotchas & format-specific sources

Baldwin-era Gretsch guitars from the 1972-1981 window use hyphenated serials (e.g. '2-365') that we don't decode — those predate the modern codes and postdate the date-coded era.
Without a listing year near 1966-1972, we require the year-digit to be in the valid 0-2/6-9 range and plausibility-check the resulting year.

Pre-1966 sequential (1939–1965)

1939–1965

Example 45000 Try it →

A single rising sequence from 001 (1939) up through ~84000 (1965). 1939-1945 = handwritten 3-4 digits on the inside of the body. 1945-1954 = 4-digit written in pencil or on a label. 1954-1965 = 5-digit on a label or headstock (~13000-84000 range). Year ranges overlap significantly across years — the serial alone narrows to a window, not a specific year.

Gotchas & format-specific sources

Pre-1939 Gretsch instruments often have no serial number at all — dating those requires feature-based analysis (pickups, hardware, binding).
Five-digit serials from this era overlap with the 1966-1972 date-coded format on the first character; the matcher tries the date-coded interpretation first and falls back to pre-1966 sequential when the year/month digits aren't valid.

Where to find your serial

Gretsch serial location varies by era. Hollowbody models usually carry a serial on a label inside the F-hole and/or stamped on the headstock. Solidbody modern models are stamped on the back of the headstock or on the neckplate.

Back of headstock (modern solidbody)

Standard location for modern Electromatic, Streamliner, and Professional solidbody models.
Label inside F-hole (hollowbody)

Modern and vintage hollowbody Gretsch instruments typically carry a serial on a label visible through the F-hole. On Baldwin-era instruments the serial may only appear on this label.
Back of headstock / top of headstock (pre-1966)

Pre-1966 Gretsch often has the serial impressed or stamped on the headstock (top or back varies by model).
