UPC Codes in Sequential Numerical Order

Read below to learn how to read your UPC codes in sequential order.

At InstantUPCCodes.com we always guarantee that the UPC codes within your order will always be delivered within sequential numerical order. However, some of our customers are unsure of what this means exactly. First, we will explain what our promise is and why it is important to receive your order in sequential order, then we will cover how to read your UPC codes in sequential order.

Please Note: All of the information regarding UPC codes in sequential order on this page pertains to UPC codes which originate from UPC prefixes originally sold by UCC/GS1 prior to the UCC lawsuit settlement date of Aug. 28th 2002. Prefixes sold prior to this date are considered static prefixes. Prefixes sold on/after the UCC lawsuit settlement date were considered variable UPC prefixes. The information within this article does not pertain to variable UPC prefixes.

Static UPC Prefixes: Issued prior to Aug. 28th 2002
Variable UPC Prefixes: Issued on/after Aug. 28th 2002

Our promise: We always guarantee to deliver each UPC code order with the UPC codes within that file in sequential order. This means that each individual order that is delivered to you has those particular UPC codes in sequential order. Please note: each order is not delivered sequentially in connection to a previous order. What this means is that if you placed an order with us 6 months ago and then you purchase another order today, the new order will not start off on the last number from your previous order. Each individual order will always be delivered with the UPC codes in sequential order, for that order.

So, why is it important to have your UPC codes in sequential order? The reason why it's important is because when we sell UPC codes in sequential order to you, we are essentially selling a "block" of UPC codes to you. Sequential UPC codes are easy for organization and for many other reasons. It has come to our attention that some UPC companies sell random UPC codes that are mixed and matched when you order with them. This can become extremely confusing to organize and deal with over time.

Example UPC code: 123456789012

Example UPC code breakdown from a static prefix: 123456 78901 2

Each UPC code is made up of 12 digits from 0-9. The example UPC code above has all 12 digits and no spaces in between the numbers. The example UPC code breakdown is the same UPC code from above with a space after the 6 and 1. The reason why we put the spaces in the example UPC breakdown number is to show the prefix number, product code and check digit.

Since all of the UPC codes that we sell, come from UCC/GS1 originated prefixes which date prior to the GS1 lawsuit settlement date of Aug. 28th 2002, then the first 6 digits of the UPC code is the static 6 digit company prefix number. The next 5 digits is the "product code". Finally, the last digit of any UPC code number is called the check digit or checksum digit. The checksum digit is calculated based off of a mathematical calculation of the first 11 digits. We have also included a breakdown of the numbers below for easy reference:

123456 - The static 6 digit company prefix
78901 - The variable 5 digit product code
2 - The check digit / checksum digit

When UPC codes are issued, the first 6 digits will remain the same as the prefix number is static. The next 5 digits of the product code will be in sequential order as this part of a UPC code is a variable section. The last digit (12th digit) of a UPC code will always be a randomized number since it's based off of a mathematical calculation of the previous 11 digits.

Below we have included an example of 5 UPC codes in sequential order:

123456 78901 2
123456 78902 9
123456 78903 6
123456 78904 3
123456 78905 0

Notice how in the above example that the first 6 digits are always the same in each UPC code, but the 5 digit product code is increasing numerically. When the UPC codes are delivered to you, there are no spaces so the UPC codes then become harder to read. They will look like this:


When we look at a UPC code number to determine if it's in sequential order we imagine as if the last digit doesn't exist for each UPC code number. We hope this article has been a help to you. If you ever have any questions regarding UPC codes in sequential order, please don't hesitate to contact us.
