A stardate is a fictional system of time measurement developed for the television and film series Star Trek. In the series, use of this date system is commonly heard at the beginning of a voice-over log entry, such as 'Captain's log, stardate 41153.7. Our destination is planet Deneb IV …'. While the original method was inspired by the Julian date^[1][2] system currently used by astronomers, writers and producers have selected numbers using different methods over the years, some more arbitrary than others. This makes it impossible to convert all stardates into equivalent calendar dates, especially since stardates were originally intended to avoid specifying exactly when Star Trek takes place.^[3]

Original stardate[edit]

The original 1967 Star Trek Guide (April 17, 1967, p. 25) instructed writers for the original Star Trek TV series on how to select stardates for their scripts. Writers could pick any combination of four numbers plus a decimal point, and aim for consistency within a single script, but not necessarily between different scripts. This was to 'avoid continually mentioning Star Trek's century' and avoid 'arguments about whether this or that would have developed by then'.^[4] The original series would be officially placed between the years 2265 and 2269, with the second pilot beginning on stardate 1312.4 and the last-produced episode on stardate 5928.5.^[5] Though the dating system would be revised for Star Trek: The Next Generation, the pilot of Star Trek: Discovery follows the original series' dating system, starting on stardate 1207.3, which is stated precisely to be Sunday, May 11, 2256.^[6]

Revised stardate[edit]

The three 1990s Star Trek series followed a new numerical convention. Star Trek: The Next Generation revised the stardate system in the 1987 Star Trek: The Next Generation Writer's/Director's Guide, to five digits and one decimal place. According to the guide, the first digit '4' should represent the 24th century, with the second digit representing the television season. The remaining digits can progress unevenly, with the decimal point usually counting days. Stardates of Star Trek: Deep Space Nine began with 46379.1, corresponding to the sixth season of Star Trek: The Next Generation which was also set in the year 2369. Star Trek: Voyager began with stardate 48315.6 (2371), one season after TNG had finished its seventh and final season. As in TNG, the second digit would increase by one every season, while the initial two digits eventually rolled over from 49 to 50, despite the year 2373 still being in the 24th century. Star Trek: Nemesis was set around stardate 56844.9. Star Trek: Discovery traveled to the year 3188, giving a stardate of 865211.3, corresponding to that year in this system of stardates.

Other stardates[edit]

Additional Star Trek media have generated their own numbering systems. The 2009 MMORPGStar Trek Online takes place on stardate 86088.58, in the year 2409.^[7] Writer Roberto Orci revised the system for the 2009 film Star Trek so that the first four digits correspond to the year, while the remainder was intended to stand for the day of the year.^[8][9][10] In the first installment of the movie trilogy, Spock makes his log of the destruction of Vulcan on stardate 2258.42, or February 11, 2258.^{[11][better source needed]}Star Trek Into Darkness begins on stardate 2259.55, or February 24, 2259.^[12]Star Trek Beyond begins on stardate 2263.02, or January 2, 2263.

Serial Number Location

Trek frame serial numbers (SNs) are typically stamped into the bottom of the bottom bracket shell. In the case of some early 80s Treks, the number is under the plastic cable guide on the bottom of the shell. Just remove the plastic cable guide to see the number. The other place Trek (or their subcontractors) stamped the SN is at the lower end of the seat tube.

Note: The SN on your original sales receipt may not match the one on your bike. Sales persons sometimes had difficulty reading the numbers.

Many Trek bottom bracket shells have a one or two letter code stamped separately from the serial number. This was made by the individual framebuilder to mark his/her work. If you know which mark was used by a particular craftsman, please let me know.

Serialization Date

The dates coded in the serial numbers, or the dates inferred from the numbers, are dates on which the new frames were stamped with serial numbers (serialized). These dates are not necessarily the same as the model year of the frame. At some time late in each year (beginning generally September or October) the frames produced were created from designs, and painted with colors, for the next year.

Hard to read?

Trek serial numbers can be hard to read. Clean the area well, and use lots of light at various angles. A suggestion by J. Hansen can help you read a serial number:

'Rub the area with candle wax of a color that contrasts with your paint. Lightly wipe it off with a rag. The wax stays in the indented area of the S/N. Now you can easily read the number. I have included a photo of the results from my bike. In this case I used a red candle to make the serial number stand out. Note that even with the serial number filled with wax, the leading '0' is almost imperceptible.'

PRIOR TO LATE 1980

Trek Serial Decoder

Before late 1980, Trek used an alphanumeric serial number scheme. Each seven-character number consists of three letters mixed with numerals. The serial number list and the code for the list are not available from Trek (but hope springs eternal). In the meantime, we have the results of the serial number decoding project:

LATE 1980 TO LATE 1986

Late in 1980, Trek changed to a new numbering system for their frames built in the U.S. The frames were numbered sequentially, beginning with number 000001. The record of the assembly runs was documented in a handwritten journal. Trek (Kevin Tita) graciously provided a copy of the journal for this web site. The list ended in November of 1986 with number 279975. This serial number system actually extended through at least 1997 (see Table II below).

The journal includes run number, model number, frame size, and serial number range. Incidental information, including dates and comments on the frames, appears sporadically through the journal. A 'run' was for a particular frame size and frame model.

We all owe thanks to Luker White who generously donated his time to convert much of the paper list to digital form.

Click on the date link in Table I below to go to the detailed serial number information for that year.

Table I - 1980 to 1986

Notes for Table I:

1. Table I contains dates of frame serializing, and are not necessarily model year. At some time late in each year (generally September or October) frames were built for (then painted with colors for) the next model year. This journal information is summarized by year in Table I. The year designations in the table are approximate; not all of the runs are sequential in time. This may be a result of subcontracting some frame fabrication.
2. For some years, the model number given may be the lowest number (or an X00 number) for a series of models that have the same frame. For example, a 1981 frame appearing on the list as a Model 610 could have been built into either a 613, 614, or 616 bike.
3. Some of the Model 170 serial numbers are 6 digits but do not follow the numerical sequence. A future task is to sort 170 numbers. Some of these are presented in the 83, 84 link at the bottom of the table.
4. Some early and mid 80s bottom brackets were marked with 58TSI or 60TSI. In the early 1980s Tim S. Isaac designed new lugs and a new bottom bracket shell for Trek. The new bottom bracket shell is typically marked with 58TSI (or more rarely, 60TSI). This designation is not part of the serial number but is a model number of the shell. The TSI are Tim's initials. The 58 or 60 refer to the angle between the seattube and the downtube.
5. Some frames in this period have a leading 'A' before the 6 digit number. This may be more prevalent on lower level models. The 'A' may not be part of the SN. Just disregard it when looking up the number in the tables below.
6. Frame Sizes in the SN list below are as given on the paper copy. For some entries, only a two-digit number was given, the extra 1/2 or 3/4 inch was dropped. So - an entry of 22 inches really means a 22.5' frame size, 19 means 19.75', 25 means 25.5'.
7. The list has two major gaps, corresponding to missing pages. Page 9 ends with SN 027870 and the next page starts with 029118. Page 61 ends with 210065 and the next page starts with 215226.
8. The SN list for 1986 has some serial number ranges with annotations about POs (purchase orders) to 'Merida'. These are for Model 800, 830 and 850 mountain bikes and Model 300 road bikes. These were made late in the year, so they probably were all 1987 models. At least some of these were provided to Trek as 'frames only'. One reported SN in these ranges, for an 850, was prefaced by the letters TML. From the serial number list, the number of Trek frames or bikes made by Merida late in 86 totaled at least 8251.
   Merida is a Taiwanese bike company that was established in 1972. It is currently a major, worldwide player in the bicycle business. See http://www.merida.com/ for information on this company.

   LATE 1986 to 1997+

This 6 digit (7 digit beginning in 1993) code extended into at least 1997, at least for some models (generally mid to upper level and made in the U.S.). The number may or may not have a leading zero, making the six digits into seven digits prior to 1993. The model is not available for these numbers but the year can be determined or estimated from Table II below. The information in the table is from serial numbers submitted by site visitors. Our thanks to them. In contrast to the serial number dates in Table I above, the years in Table II represent model years, not the date the serial number was applied.

Table II - Model Years 1987 to 1997

FOREIGN-BUILT FRAMES AND BIKES 1982 to MID 90s

Three different serial number forms have been submitted for 1983 Trek Model 400 frames. One, marked 'made in Japan', begin with JS followed by six numerals. The SN was located on the bottom of the bottom bracket. A second serial number is 81765. According to the Trek-provided SN list, this corresponds to a 22' (22.5') Model 400 frame made in 1983. This SN form is for frames/bikes made in the U.S. The number was marked on the bottom of the bottom bracket. The third number is 403300950, which indicates foreign built, but the nation of origin sticker was missing. This number was marked at the bottom of the down tube. It is likely this 400 was made by the same manufacturer as the 1984 bikes described in the paragraph below. For the 1983 Model 400, it appears Trek used three sources for their frames or complete bikes.

Several 1984 Trek 460s, 420s and 400s have been reported with 9 digit numeric serial numbers stamped on the lower seat tube instead of on the bottom of the bottom bracket. These frames, or complete bikes, apparently were made in Japan by an outside contractor. The numbers submitted are in the range of 401000000 to 440000000.

An 8 or 9 character alphanumeric code was used for mid- and low-level frames subcontracted in Taiwan. Most of these bikes were labeled 'Made in Taiwan'. This form of serial number appears to have been used during the period 1987 to 90. The number leads with a T (for Trek?) then a numeral, a letter, then five numerals. Sean Hickey suggested the first numeral is the year of manufacture, and the letter is the month of the year (A - L). This is confirmed by serial numbers that were submitted by other Trek owners.

A later 8 and then 9 character alphanumeric SN scheme, used beginning in about 1989, also begins with a T (for Trek?). These later T numbers were used on lower level subcontracted frames but do not follow the 2nd and 3rd or 3rd and 4th character date meanings above.

Trex Decorative Panels

Beginning in about 1994, an 8 character alphanumeric code was used for some Trek bikes made in Taiwan. It begins with G and another letter (e.g. GQ, GR, GS, GV and GZ). These are followed either by: 6 numerals, or a number, a letter, followed by four numerals. The first numeral in the SN is likely the year of serialization.

MID 90s 3-PART SERIAL NUMBERS

During the mid to late 1990s, Trek used a three-part serial number and information code system on the bottom of bottom bracket shells. This scheme seems to have been used for bikes manufactured overseas and perhaps for bikes made in the USA by Trek. The scheme of the numbers varied, perhaps as a function of the actual foreign manufacturer. Examples are given below:

Example 1

14 066 71
990 18 31 9406

The first line is the actual serial number. The information on the left lower line is model number (990) and frame size (18 inches). On the right lower line the meaning of the 31 is unknown. The 94 is the manufacturing year (1994) and the month (06 or June)

Example 2

WTU 2054748N
750 17 B10407

The upper line is the serial number. The left lower line is model (750) and frame size (17 inches). The meaning of the B1 is unknown. This is from a 97 model bike, so likely the 7 is the year.

Trek Discovery Imdb

Example 3

For a 15' women's 1999 model 720, the numbers are:

T B1 0407 WTUD01330R A0199

Here the model number and frame size are absent. The center number is the actual serial number. The 99 is the year, and the 01 may indicate January.

Example 4

For a 18' 1997 Model 8000 mountain bike:

WTU 1981461
M B1 0406 8000 18

The top line is the serial number. Interestingly, the 1981461 is probably within the realm of 1997 in Table II above. The 8000 and 18 are model and size in inches. The 0406 may not be a date code, since it does not corrspond with what I believe is the year of the bike.

If you have a serial number of this form, please send it along with information about your bike. Thanks to Arnold O' Sioléir, Wayne Snyder, Christine Flynn, and bidaci for the info above.

MODERN WTU NUMBERS

Trek has used the WTU designation in their serial numbers from the mid-90s to today. Trek has used these numbers not only for Trek bikes but also for their Klein, Gary Fischer and Lemond brand bikes.

In a Safety Recall Notice dated 1 May 2009, Trek describes some features of 2009 serial numbers. It states 'The first three digits after “WTU” represent the sequential date; the number of days from the beginning of the year. The letter at the end of the serial number represents the model year.' The notice states that a final leter D indicates 2009.

For the serial number WTU301D86571D, the framewas made on the 301st day of the year. The final D indicates the bike was made for the 2009 model year. Extending backwards from 2009 one gets the following last character meanings.

Trek 2002 4300 had no final letter in SN

JAZZ BY TREK

Jazz is a line of foreign-built, entry-level bicycles that Trek sold in the early 90s. (See the history page for a bit more info and the brochures page for a 93 catalog). There seems to be at least three serial number types:

1. A Flipside model had the serial number JT0116 stamped on the bottom bracket shell. The JT probably stands for 'Jazz' and 'Trek'. The numbers may be the sequential frame number, beginning at 0001.
2. The second type is a 10-character serial number. The first two characters are letters which are followed by eight numbers. Examples are JT09010099 and FI08003231.
3. A Latitude model has a 10-digit, all-numeric serial number: 1230707859. This number also was stamped on the bottom of the bottom bracket shell.

These three serial number forms may mean that Trek used at least three subcontractors for the Jazz line.

MISSING SERIAL NUMBERS

A few owners of early Treks, mostly, from 1976 through the early 80s, report their frames are not marked with serial numbers. A past Trek employee wrote that the police in the Madison and the surrounding area said TREK was famous for bikes with no serial numbers. Seems hundreds didn't get any numbers at all. The serial number guy just missed a few?

Three other possibilities: 1. In the early years Trek allowed, and even encouraged, their workers to use company equipment and materials to build personal frames after hours. These frames often were not serialized. The practice stopped after production was increased, resulting in little available down time for the equipment. 2. The serial number on a repainted frame that was not first stripped, may disappear under the new paint. 3. The number is under the plastic cable guide attached to the bottom of the bottom bracket shell.
