Sigma Lens Serial Number Check

Recent Sigma lens names have been quite short and, officially, this lens is simply called the Sigma 120-300mm F2.8 DG OS HSM. As you can see, it is a telephoto zoom lens with focal length range of 120-300mm and a wide maximum aperture of f/2.8 throughout.

Just like any product with a serial number, the one found on your Nikon lens is a way to identify the model. Unlike cars and other larger items, the serial number on a Nikon DSLR lens can repeat on the same models. A lens serial number gives you and potential repairers a chance to look up more information about the lens you own. Sometimes the serial numbers are even used repeatedly and on different models and the length of the numbers differs depending on when the lenses were produced. This can be very confusing for most people and understandably so. Typically, a serial number will have 6 digits, but when production of the lens goes beyond 999,999 the length of the number will vary. The most important part of the Nikon lens serial number is the first digit. This gives an indication of where it was made. Here is a rundown of what the first digit means: 1 – Unused by Nikon unless for prototypes 2 – Made in Japan 3 – Made in the USA 4 – Made in Europe but not the UK 5 – Made in Canada 6 – Made in New Zealand or Australia 7 – Made in Asia but not Japan 8 – Make in the United Kingdom 9 – Unused by Nikon The first number on the Nikon lens serial number typically indicates where it was made and the following number is the product number. This is why lenses that have reached production over 999,999 have a different serial number length. Today this format isn’t very strictly followed anymore because more and more lenses are produced by Nikon. This is just a guide of what you can expect from looking at the serial number on your Nikon lens.

Where To Find an How to Check Nikon Lens Serial Numbers

Now that you have some understanding about serial numbers you might be curious about how to check Nikon lens serial numbers on your own Nikon lens. Serial numbers can be found in different places on your lens. They do not have a standard location, but they are fairly easy to find. Just have a look at your Nikon lens and scan the surface. The serial number can be easily found because it is usually printed in white to help it stand out from the black lens. Some might be found on the body of the lens while others are on the glass. Have a look around and you will eventually find the serial number. If you are having trouble with finding the serial number on your lens due to the numbers being scratched out from wear and tear, check the original box it came in. The box will usually include the lens’s serial number.

What To Do With A Nikon Lens Serial Number

Most people only pay attention to the lens’s serial number when they bring it in for repairs or when the lens is stolen. Although those are the important times to really have a look at your Nikon lens serial number, there are ways to check Nikon lens serial numbers online. You can find websites that can give you helpful information about your Nikon lens. Information like production date, status of production, whether or not the model has been discontinued and other interesting facts about the Nikon lens you own are available if you know where to look. Another major benefit of finding the serial number on your Nikon lens is to check to see if you have bought an original product or a fake. With so many fake products on the market, you cannot be too sure if you have purchased an original Nikon lens or a fake one. With a serial number, you can double-check with Nikon to see if the lens you have is an original.


Check your Nikon lens for the serial number and try searching for it online. There isn’t a large database available, but you can find a lot of information. If you are suspicious about the new Nikon lens you bought because the serial number doesn’t look right, contact the seller or check with Nikon to confirm. A serial number might just look like a bunch of numbers, but those numbers mean something, so it’s worth knowing how to check Nikon lens serial numbers.

How old is your Canon lens? With either the lens' serial number or date code, that question can be answered.


Canon has been transitioning to a 10-digit lens serial number (starting in 2008 with the Canon EF-S 18-200mm f/3.5-5.6 IS Lens) and ending the inclusion of a separate manufacturing date code. While date codes and the shorter serial number are still found on some lenses, this inclusion will likely end completely. We loved the date code because it made aging a lens easy. However, now we can age a lens based on the serial number alone.

For information on determining the age of a pre-10-digit serial number lens, see the section on interpreting the old date code below.

Determine the age of a Canon lens based on the 10-digit serial number

To age a Canon lens using the 10-digital serial number, we dissect the serial number as follows:


The DD is the key to the date the lens was manufactured - the production date code. The Canon lens date code chart is shown below.

Sigma Lens Serial Number Check

These dates should be viewed as approximations and should be used for your amusement as the estimates are not guaranteed correct. Please send any discrepancies you find. Note that Canon EOS DSLR camera body serial numbers, at least for 2013, do not follow this chart. Also please note that future dates shown in the table are predictions/expectations.

The third digit in the serial number, C, may be a charge/batch type of number. Canon has been using this number to indicate lenses needing specific service-related updates such as firmware.

The remaining digits in the serial number, SSSSSSS, are a uniquely-identifying number of the lens – likely within the production month.

Please note that, while the overall chart is holding out nicely with the lenses we've checked (including several late-2014 models), it is a work-in-process. In part, the numbers might be shifted by a month or so. Again, please send us any discrepancies you find.

Special thanks go out to friend-of-the-site Norbert for his role in the development of this chart.

To determine the age of a pre-10-digit serial number Canon lens bearing a date code

Until phasing out the practice starting in 2008, Canon included a date code beside the rear lens element of many (but not all) lenses (note that some 2012-manufactured lenses retain the date code). The date code (as seen below) is in the form of 'UR0902'. This code is also present on some other Canon products including camera bodies.


The first letter, 'U', indicates that the lens was made in Canon's Utsunomiya, Japan factory. Prior to 1986, this letter is moved to the last position of the date code.

U = Utsunomiya, Japan
F = Fukushima, Japan
O = Oita, Japan

The second letter, 'R', is a year code that indicates the year of manufacture. Canon increments this letter each year starting with A in 1986 and prior to that, A in 1960 without the leading factory code. Here is a table to make things simple:

Sigma Lens History

A = 2012, 1986, 1960
B = 2013, 1987, 1961
C = 2014, 1988, 1962
D = 2015, 1989, 1963
E = 2016, 1990, 1964
F = 2017, 1991, 1965
G = 2018, 1992, 1966
H = 2019, 1993, 1967
I = 1994, 1968
J = 1995, 1969
K = 1996, 1970
L = 1997, 1971
M = 1998, 1972
N = 1999, 1973
O = 2000, 1974
P = 2001, 1975
Q = 2002, 1976
R = 2003, 1977
S = 2004, 1978
T = 2005, 1979
U = 2006, 1980
V = 2007, 1981
W = 2008, 1982
X = 2009, 1983
Y = 2010, 1984
Z = 2011, 1985

The first two numbers, '09', is the month number the lens was manufactured in. Month 02 is February, month 11 = November. The leading zero of the month code is sometimes omitted.

The next two numbers, '02', are meaningless in determining how old a Canon lens is. This is a Canon internal code (that is occasionally omitted).

You now know the manufacture date for your lens - But - You cannot know how long the lens was in inventory, in shipping transit and on a shelf until it was originally purchased (without having the original receipt or a reputable person accurately informing you).

Sigma Serial Number Date Check

The Canon lens date code in the sample picture indicates that this Canon EF 24-70mm f/2.8L Lens (I know the lens model because I took the picture - not from the date code) was made in Utsunomiya, Japan in September 2003.
