SERIAL NUMBER LOCATION:

After the 'Bicycle Boom' of the 1970s, however, Schwinn's proprietary frame-building technology and heavier bikes became less economically viable in an increasingly weight-obsessed industry-resulting in millions of unique vintage and antique bikes that can be identified by their serial numbers.
Search for bikes that have been registered on Bike Index. The non-profit bike registry Sign up ☰ Search bikes. Serial WE19070616; Primary colors Silver, gray or bare metal. Schwinn World Sport Serial gm612263; Primary colors Black, Red, and Yellow or Gold; Stolen 2020-12-05T15.
Enter your Schwinn serial number in the box and click 'find' to see what date and year your Schwinn bike was manufactured. This tool searches a database of Schwinn serial numbers and if it finds a match to your serial number then it will display the information available for your bike. Notes: This tool works for Schwinn bikes from 1948 to 1982.

NUMBERS ARE NOW LOCATED ON THE LOWER LEFT OF THE HEADTUBE

The Schwinn serial numbers that date the bike to the fall of 1954 or 1956, but I believe the Serial numbers for 54 and the 56 were located on the Left Rear Dropout - not located on the bottom bracket of the pedal crank housing.

NUMBERING SYSTEM:

THE FIRST 'LETTER' IS THE MONTH, THE SECOND 'LETTER' IS THE YEAR.
THE LETTERS ' I ' and ' O ' ARE SKIPPED
TO AVOID CONFUSION WITH NUMBERS 'ONE' and 'ZERO'.

Examples:
AF***** = Jan. 1970,... ('A' = Jan., 'F' = 1970)
GL***** = July. 1975,... ('G' = July., 'L' = 1975)
MR***** = Dec. 1980,... ('M' = Dec., 'R' = 1980), etc.

THIS CHART APPLIES TO CHICAGO SCHWINN`S ONLY.

During the 1980s, Greenville used the old letter-digit

(e.g. F8 = June 1988)system which Chicago abandoned in 1965,
when it changed to the two-letter system.

ON NEWER BIKES:
you can find a 4 digit serial number lightly stamped onto the headbadge.
The first three digits are the numerical day of the year,
and the last digit is the last digit of the year.
