Remington 870 Serial Number Lookup

UPDATE: Remington 870 Serial Number Lookup

I have found this information somewhere on the web:

Remington 870 Serial Number

Remington 870 Serial Number

Remington Year of Manufacture Codes maybe found on the barrel of your Remington rifle [or shotgun] on the left side, just forward of the receiver; the first letter of the Code is the month of manufacture, followed by one or two letters which are the year of manufacture. For shotguns with removeable barrels, the code will be valid for the manufacture of the barrel; maybe for the receiver, as barrels do get switched around.

According to the “Blue Book of Gun Values”, the coding continues as follows:

Month Codes: [first letter] B – L – A – C – K – P – O – W – D – E – R – X
1 – 2 – 3 – 4 – 5 – 6 – 7 – 8 – 9 – 10 – 11 – 12

* the years 1943 though 1953 had double letters: ie, MM = 1943

As maybe seen, the year code letters duplicate; some knowledge of when the model was introduced should resolve the actual year of manufacture.

I have contacted Remington and they confirmed that information above is correct.

    Not quite as easy as that for the older 870’s…. I believe that they didn’t started using the standard Reminton Year Prefix letter on this model till ’68. Had to email Remington at to find out date of mine that didn’t start with a letter.

    • Vitaly Pedchenko January 21, 2012

      Ahhh, I see. I’ve heard that they began coding their firearms since 1921

  2. Rich January 21, 2012

    Varies a lot by model I think. Some of their .22 rifles didn’t even have serial numbers till the 60’s!

  3. Swedala January 26, 2012

    Kind of confusing this. Are we talking about the serial number or the dating code on the barrel? The title of this post as well as the photo indicates the serial number on the receiver. Does the two letter prefix on the serial number correspond to the month and year dating code? My -74 Wingmaster only has a dating code on the barrel and no letter prefix in the serial number, just numbers. It has by the way not the same location on the receiver as a modern day 870 so it is hidden by the Mesa side saddle.

    Swedala, just found following information: “Between August 9, 1999 and October 1, 2001, Remington removed the date coding from the serial numbers on the barrels but continued to code the serial number on the box” (

  5. Vitaly Pedchenko March 12, 2012

    Swedala, I was wrong, we need to use dating code on the barrel, not the serial number on the receiver.

    I just bought a used 870. I found “EX” stamped on the barrel. According to this, the barrel (which is removable) could have been made in 1973 or 2002. Is that right? Looking at the wear on the gun and the overall look I think 1973 is more likely, but it was owned by a police department so maybe it’s just seen a lot of use. How would you go about narrowing that in?

  7. Lee May 1, 2012

    Does the 870 police model with the wooden stock and gloss metal (4899 I think) have a removeable barrel?

    • Vitaly Pedchenko May 10, 2012

      I think that all 870 shotguns have removeable barrel. There are no 870 shotguns with fixed barrel.

  8. Bob September 26, 2012

    My receiver has a s/n of 209938V and Remington confirmed it’s 1952, BDL grade.

  9. jim December 13, 2012

    Can someone tell me what year this Remington 870 is. I have a serial # of s5400411v
    Thanks, Jim

  10. Rustynail January 24, 2015

    My 870 is a 16 ga. and the letters on the barrel are PWW and the serial # is XXXXXW. The same number is under the letters on the barrel. According to the chart above WW guns were manufactured in 1950, but from what I have found Remington didn’t start selling the 870 until 1951. Anyone have any idea’s about this?

    • Steve November 29, 2015

      Your gun was built June 1972
