Different Inventory Numbering Methods
There are several approaches to inventory numbering, each with its own advantages and disadvantages. Let’s explore some of the most common methods.
Sequential Numbering
This is the simplest method, assigning consecutive numbers to each new product as it is added to the inventory.
How it Works: Each item receives the next available number in the sequence (e.g., 001, 002, 003…).
Advantages: Easy to implement and understand. Requires minimal setup.
Disadvantages: Provides no information about the product itself. Difficult to categorize or group items. Can become cumbersome with a large inventory.
Block Numbering
This method assigns blocks of numbers to different product categories.
How it Works: Assign a range of numbers to each product category (e.g., 100-199 for shirts, 200-299 for pants).
Advantages: Allows for some level of categorization. Easier to locate items within a specific category.
Disadvantages: Requires careful planning to allocate sufficient numbers to each category. Can be inefficient if some categories grow much faster than others. May result in gaps in the numbering sequence.
Significant Digit Numbering
This method uses digits within the inventory number to represent specific product attributes.

- 1234: Product Category
- 05: Color (e.g., 05 = Blue)
- M: Size (e.g., M = Medium)
- R: Material (e.g., R = Cotton)
Advantages: Provides detailed information about the product within the number itself. Facilitates easy filtering and sorting.
Disadvantages: Requires significant upfront planning to define the meaning of each digit. Can be complex to implement and maintain.
Mnemonic Numbering
This method uses letters or abbreviations to represent product characteristics.
How it Works: Combine letters and numbers to create memorable and descriptive codes. For example, “SHIRT-BLU-M” could represent a blue shirt in size medium.
Advantages: Easy to remember and understand. Can be very descriptive.
Disadvantages: Can be limited by the number of available abbreviations. May not be suitable for large or complex inventories. Prone to inconsistencies if not carefully managed.
SKU (Stock Keeping Unit) Numbering
SKU numbering is a more advanced method that combines elements of other approaches to create unique and informative product identifiers.
How it Works: An SKU is a unique alphanumeric code that identifies a specific product, taking into account various attributes such as brand, style, color, size, and other relevant characteristics. For example, an SKU like “ADIDAS-TEE-WHITE-L” could represent an Adidas t-shirt in white, size large.
Advantages: Highly descriptive and specific. Facilitates accurate tracking and reporting. Enables efficient searching and filtering.
Disadvantages: Requires careful planning and consistent application. Can be more complex to implement than simpler methods.
Barcode and QR Code Systems
While not numbering systems in themselves, barcodes and QR codes are often used in conjunction with inventory numbers to streamline tracking and data entry.
