Here’s a quick serial number lookup that will tell you the Bryant age of unit. This page explains how to read a Bryant serial number
Bryant HVAC Age
The first two numbers represent the week of the year, 01 for the first and 52 or 53 for the last.
The second two numbers represent the year – 97 is 1997, for example, and 08 is 2008.
Bryant Serial Numbers
Bryant has used six different styles of serial numbers since the 1960’s. The current style has been used since 1984 and is used on Bryant furnaces, air conditioners, air handlers, and heat pumps.
Not Model #s: No doubt you understand this, but to be clear for all, this post is about Bryant serial numbers, not Bryant model numbers that have nomenclature related to series, capacity, and performance of Bryant HVAC equipment.

Where is the Bryant Serial Number?
The serial number can be found on the rating or data plate sticker on your unit.
For outdoor units such as air conditioners and heat pumps, the rating plate is usually located on the back of the unit above the service valve connections.
On furnaces, the rating plate can be found on the inside of the front door panel.
Serial Number Characters That Indicate the Manufacture Date
In each of these examples, the characters that indicate the manufacture date have been underlined. The other numbers and letters identify the plant where the unit was made and the sequence of manufacture.
How to Read a Bryant Serial Number
Here are the ways to determine Bryant HVAC age for furnaces, ACs and heat pumps. There is a lot of overlap and, frankly, confusion in reading Bryant serial numbers. Everything is sorted here.
Style # 1 – 1985 through current (2022): 10 Character Serial Number
Because this style of serial number has been used since 1985, you will find it on the majority of Bryant HVAC equipment in service today making the date lookup an easy task.
In Style # 1 the 10 character serial number will consist of 4 numbers, a letter, and then 5 more numbers.
Sample Serial # – 3709E07806
Week: First 2 numbers represent the week from 01 – 52. The numbers here are 37, so the 37th week, which is in September.
Year: The 3rd and 4th numbers indicate the year from 85 – 99 (1985 – 1999) and 0 – 22 (2000 – 2022) In this case, the numbers are 09, so the unit was made in 2009.
Manufacture Date: September 2009
Sometimes the actual manufacturing date is included on the rating plate. This is what a Style # 1 Bryant rating or data plate looks like.

Style # 2 – 1980s: 9 Character Serial Number
This style was used primarily in the 1980’s and consists of nine numbers.
Sample Serial # – 820304091
Year: The 1st and 2nd numbers are the year the unit was made, so 1982.
Month: The 3rd and 4th numbers indicate the month of manufacture (01 – 12). In this case the number is 03, so the month is March.
Manufacture date: March 1982
Style # 3 – 1980 through 1984: 8 Character Serial Number
This style uses an 8 character number and always begins with one letter followed by one number and then another letter, then five numbers.
Sample Serial # – N3D15009
These Bryant serial numbers begin with a letter between M and Z, with the exception of the letters “O” and “U”, which were not used.
Month: Here the letter is an N indicating February – see below:
January = M
February = N
March = P
April = Q
May = R
June = S
July = T
August = V
September = W
October = X
November = Y
December = Z
Year: The 2nd character is always a number (0 through 4) and indicates the manufacture year.
0 – 1980
1 = 1981
2 = 1982
3 = 1983
4 – 1984
Here the 2nd character is a 3, so the year the unit was made is 1983.
Manufacture Date: February 1983
Style # 4 – 1970 through 1979: 7 Character Serial Number
To decode Bryant serial numbers from this era, know that they always begin with a letter between A and L, followed by 6 numbers.
Sample Serial # – G953790
Month: Here the letter is G indicating July – see below:
A = January
B = February
C = March
D = April
E = May
F = June
G = July
H = August
I = September
J = October
K = November
L = December
Year: The 2nd character is a number (0-9) and represents the manufacture year as below:
0 = 1970
1 = 1971
2 = 1972
3 = 1973
4 = 1974
5 – 1975
6 – 1976
7 – 1977
8 = 1978
9 = 1979
Manufacture Date: July 1979
Style # 5 – Used in the 1960s: 7 Character Serial Number
Now we’re talking about some really old equipment! These Bryant serial numbers include 7 characters which are all numbers. The 1st number in the sequence indicates the year – 0 to 9 (1960 -1969). Pretty simple.
Sample Serial # – 7825915
Year: The 1st number is a 7, so the unit was made in 1967.
Month: The month of manufacture is not indicated in the serial number nomenclature.
Style # 6 – Used from 1960 through 1979: 7, 8, or 9 Character Serial Number
Style # 6 can have different numbers of characters, but the date nomenclature is always the same.
The serial number will start with one or two numbers followed by a letter. The number or numbers before the letter indicate the week of manufacture, and the letter represents the year of manufacture. All Style # 6 serial numbers use the letter code in the chart below to indicate the manufacturing year.
Here are three ways this style is used. Again, see the Chart below to decode the Bryant serial number.
Sample Serial # – 24T793515 – 9 characters
Week: The first 2 numbers are 24, so this is the 24th week of the year which would be June.
Year: The letter is a T indicating the year 1966– see chart below.
Manufacture Date: June 1966
Sample Serial # – 33M48592 – 8 Character Serial Number
Week: In this example, the numbers are 33, indicating the 33rd week of the year which would be in August.
Year: The letter is M which is 1961 – see chart below.
Manufacture Date: August 1961
Sample Serial # – 5F28763 – 7 Character Serial Number
Occasionally with the 7 character serial numbers from this period, the first 2 or 3 characters that represent manufacture date, are separated from the rest of the numbers with a space. Here is an example of the 7 character serial number above with the space included – 5F 28763.
Week: The only number before the letter here is a 5 which represents the 5th week of the year and would be in February.
Year: The letter F indicates 1977 – see chart below.
Manufacture Date: February 1977
Use the chart below to decode the year for all of the Style # 6 serial numbers:
L = 1960
M = 1961
N = 1962
P = 1963
R = 1964
S – 1965
T = 1966
U = 1967
V = 1968
W = 1969
X = 1970
Y = 1971
A = 1972
B = 1973
C = 1974
D – 1975
E = 1976
F = 1977
G = 1978
H = 1979
