Your product serial number is a unique number that is required for product registration which in turn qualifies you for all support offered for that product. Please note that all MOTU serial numbers cannot contain spaces or dashes when entered into our database. Here are some pointers to help you find your serial number.
Software product serial numbers are printed on the registration card as well as on the first page inside the front cover of your software product manual. If you've removed your registration card to register your software product with MOTU, you'll find the serial number duplicated on the remaining part of the page.
A Digital Performer Competitive Upgrade will not come with a serial number. To register a Digital Performer Competitive Upgrade please follow the directions included on the registration form that came in the package.
This page will help you determine the age of your older Kawai acoustic piano. The first step is to find the serial number of your instrument. The serial number identifies the year an instrument was manufactured and is the key to all future warranty service and repair (if needed). Its location varies depending on the type of instrument.
For Kawai upright pianos, the serial number is located in one of two places: (1) the top right side of the iron plate (near the tuning pins) or (2) at the top center of the plate between the bass and treble sections. You can normally find it easily by lifting the piano lid. For Kawai acoustic hybrid pianos (K200- ATX3 and K300 AURES), the serial number is located at the top center of the iron plate under the Kawai logo.
The serial numbers listed are the approximate first number produced for the year shown. Starting letters other than A or F should be disregarded. Serial numbers for different models are not always sequential, so actual dates could vary.
In the early 1980s, Weber introduced a portable grill called the Hot Shot Table Top Gas Grill, the same grill we know today as the Go-Anywhere Gas Grill. We have no information to indicate that the early versions of these grills had serial numbers or were date coded.
In 1985, Weber introduced the Genesis 1/2/3/4/5 series of grills; in the early 1990s the Spirit series of grills; and in 1993 the Genesis 1000/2000/3000/4000/5000 series of grills. From 1985-1993, Weber gas grills were assigned serial numbers to indicate grill type/model and fuel source (liquid propane or natural gas), but they were not coded to indicate date of manufacture or model year.
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.
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.
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.
"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."
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:
The second number is the last digit of the year, 6, 7, 8, 9 (for 197X) and 0 for 1980. See note below, ****, for year exceptions. Again, this is the date of serializing, not necessarily model year.
The rest of the code defines time to a month. Perhaps once Trek was nearing more than 2600 bikes/frames of a given model per month, a new serial number scheme needed to be developed. Hence the change to the sequential system started in late 1980.
A. Serial numbers beginning with M or N (41X and 61X bikes or frames) seem to have a different meaning for what normally is the year digit. The year digit is the fourth character in the number. In the 50 M and N serial numbers that have been sent in by owners, the year numbers go from 0 through 9. The remaining part of the serial numbers seem normal.
According to the brochures, Trek did not make 41X and 61X bikes or frames during 76, 77, 78, and 79 and also not in 83, 84, 85, 86, 87, 88, or 89. These serial numbers apparently do not follow the year convention used for other Trek models. It is likely these frames, SNs beginning with M or N (Models 41x and 61X), were contracted out, and were given the old serial number form so as not to interfere with the sequential numbers being assigned by Trek in their shop, which began in late 1980.
This variation to the SN system may have been done to extend the numbering system. By using the fourth character as an extension of the last three, the serial numbers could be extended from 2600 possible combinations to 26,000 for a given month.
C. Three 950 frames have been reported that contain unlikely year codes of 5, 6 and 7. It is very unlikely they were made in 1975, 76, or 77, more likely (from the brochures) 1980, 81, or 82. Another 950 frame was reported with a 0 in the year code, but was painted as a 1982. From the geometries, they probably were custom frames. Trek apparently used a different coding method for these frames, perhaps so as not to interfere with the production frame serial numbers.
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.
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.
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.
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.
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:
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) 2b1af7f3a8
