Barcode Technology - 4-State (PastBar)
Hide the description
PostBar, also known as CPC
4-State, is the black-ink
barcode system used by Canada
Post in its automated mail
sorting and delivery operations.
It is similar to other 4 State
barcode systems used by
Australia Post and the United
Kingdom's Royal Mail (from which
it derives), but uses an
obscured structure and encoding
system unique to Canada Post.
This particular bar code system
is used on "flats" (which are
of mail, such as magazines) and
Although all 4 State Bar Codes
are based upon the same
character set and all barcodes
look very similar, there
are nevertheless strong
distinctions, ensuring the
uniqueness of the individual
codes. For the main part, these
distinctions lie in the
algorithms for the check digit
calculation, but also in the
prefix and affix of the
Furthermore, some of these codes
only support figures, others
however support also letters.
Different compression procedures
are also used for a compact
display of the information
characters. The user must in no
way carry out any substitutions,
as for example to print out the
Canadian post barcode (Canadian
Post Corporation) for mail to
England (Royal Mail Customer
This symbology, derived from the
RM4SCC system used by the
British Royal Mail, uses a
series of bars, each of
which can individually have one
of four possible states, to
encode information used in
automated sortation and delivery
onto each piece of mail. Each
bar can either be short and
centred (known as a tracker),
medium and elevated (an
ascender), medium and lowered (a
descender), or full height. This
symbology also uses an element
known as a Data Content
Identifier (or DCI), which
specifies what types of
information are encoded into
each barcode, such as postal
codes, customer information, and
exact delivery points. The
information that goes into each
barcode is obtained from the
address printed on the front of
the envelope it is ultimately
printed on, as well as the
physical dimensions of each
piece of mail. This code also
uses a Reed-Solomon error
correction technique, so that in
case a particular piece of mail
is mishandled, the information
encoded in the barcode can still
be correctly decoded.
4-State is one of the many
barcode formats currently in
A Barcode is a method of
representing data in a visual,
The barcode formats has two
One-dimensional (1D) ---
Barcodes represented data by
varying the widths and spacings
of parallel lines.

other geometric patterns to
4-State is 1D barcode.
4-State is variable with
no fixed length.
Owing to the predefined setup of
every single character, i.e.
each consisting of two
descenders and two ascenders,
the necessary security is
already given. Further, the code
contains a check digit that is
automatically generated by the
?Visual Bar Code Designer“. The
check digit is calculated
separately for the single postal
administrations (e.g. Royal
Mail, Australia Post, etc.)
according to different
specifications, so that no
mix-up of the 4 State symbols
can occur between the individual
Most barcodes display their
corresponding values below them,
which makes it possible to human
read and manually enter
the barcode values into the
equivalent system when the
barcode label is worn out and
cannot be read by the barcode
The Advantages of using
If you want to reduce costs and
save time, using barcodes is a
good choice. Whether you are a
company or a non-commercial
organization, to improve
efficiency and reduce overhead,
barcodes are a valuable and
viable option, which is
economical and reliable.
Using a barcode system can make
the working process simple and
easy, so it can reduces the
employee training time. It only
takes a few minutes to master
the barcode scanner to
collecting data, employees no
need to familiar with the entire
inventory or pricing process.
This also reduces the cost of
The bar code design and printing
cost are low. Generally
speaking, no matter how they are
used or where they are posted,
the cost is not high. They can
be customized economically, in a
variety of finishes and
Barcodes are cheap and
user-friendly, providing an
indispensable tool for tracking
data from pricing to inventory.

comprehensive bar code system is
FAQ About 4-State Barcode
What is the
historical origin of the 4-State(PostBar) barcode?
4-State(PostBar) barcode is a barcode used by postal
services that consists of four barcodes of different heights
that can represent numbers and letters.
origins date back to 1949, when Norm Woodland and Bernard Silver
invented the omnidirectional barcode symbology. Later, they
improved this symbol into a circular barcode, which was patented
barcode is a variant developed on the basis of the circular
What industries are
4-State(PostBar) barcodes mainly used in?
are mainly used in postal services and can indicate the starting
and ending location, category, date and other information of the
in different countries and regions use different barcodes, such
as the Intelligent Mail barcode in the United States, the Royal
Mail 4-State barcode in the United Kingdom, the Japan Post
barcode in Japan, etc.
What is the format
of the Royal Mail 4-State barcode?
The Royal Mail
4-State barcode format is a character set based on the 4-State
barcode symbology, created by Royal Mail.
It consists of
four barcodes of different heights, which can represent the
numbers 0-9 and letters A-Z. It also contains a format control
code (FCC) that indicates the type and length of the barcode.
Its length can be 23, 25, 29 or 31 bits.
characteristics of 4-State(PostBar) barcode
It consists of
four barcodes of different heights, representing 0, 1, 2 and 3
It can represent
numbers 0-9 and letters A-Z, and each character is represented
by four barcodes.
It contains a
format control code (FCC) that indicates the type and length of
It also contains
a checksum to detect whether the barcode is correct.
the standards for 4-State(PostBar) barcodes? Why develop this
barcode standard is developed by postal agencies in different
countries and regions to improve the efficiency of mail sorting
For example, the
Intelligent Mail barcode in the United States is developed by
the United States Postal Service, and the Royal Mail 4-State
barcode in the United Kingdom is developed by Royal Mail.
The purpose of
formulating this standard is to take advantage of the high
density and readability of barcodes to encode relevant
information of mails in barcodes to facilitate machine
recognition and processing.
4-State(PostBar) barcodes still in use?
barcode is a graphical identifier used for mail sorting that
consists of black and white bars of varying heights.
It is still used
in countries such as the UK, Netherlands and Australia.
What is the
difference between 4-State(PostBar) barcodes and other barcodes?
difference between the 4-State barcode and other types of
barcodes is that its bars come in four different heights instead
of just two (like EAN-13 or UPC-A).
It can also
encode numbers and letters, not just numbers.
It is primarily
used for mail sorting and tracking, not merchandise
What are the
advantages and disadvantages of 4-State(PostBar) barcoding?
Low cost and high
efficiency, it can improve the speed and accuracy of mail
sorting and tracking.
It can also
encode more information, including numbers and letters.
The data capacity
is small (about 30 characters), the size is large, and it is
easily damaged (cannot be read after being damaged).
It also requires
specialized scanning equipment and software.
