This article explains what an inventory number is, how a good numbering system is structured, and provides examples.<\/p>\n<h2>Key Points at a Glance<\/h2>\n<ul>\n<li>The inventory number uniquely identifies each item.<\/li>\n<li>Systems are either <strong>on an ongoing basis<\/strong> or <strong>accordingly<\/strong> (structured) organized.<\/li>\n<li>A good system is clear, expandable, and simple.<\/li>\n<li>When combined with a barcode or QR code, the number becomes scannable.<\/li>\n<\/ul>\n<h2>What is an inventory number?<\/h2>\n<p>One <strong>Inventory number<\/strong> is a unique identifier assigned to exactly one item. It links the physical object to its data record in the system and remains unchanged throughout its entire service life. This allows each item to be identified beyond a doubt at any time\u2014when it is issued, when its location changes, and during inventory.<\/p>\n<h2>What is the structure of an inventory number?<\/h2>\n<p>There are two basic approaches:<\/p>\n<ul>\n<li><strong>Sequential number:<\/strong> Simply numbered sequentially, e.g., INV-0001, INV-0002. Simple and less prone to errors, but without any additional information.<\/li>\n<li><strong>Caller ID:<\/strong> Structured using code segments for category, location, or year, e.g., IT-BER-2026-014. Provides more information but requires more maintenance.<\/li>\n<\/ul>\n<h2>Examples of Number Systems<\/h2>\n<figure class=\"wp-block-table\">\n<table>\n<thead>\n<tr>\n<th>System<\/th>\n<th>Example<\/th>\n<th>Meaning<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Ongoing<\/td>\n<td>INV-000842<\/td>\n<td>842.

Descriptive numbers are worthwhile if the number is also supposed to provide information immediately, even offline.<\/p>\n<h2>Inventory Number and Barcode\/QR Code<\/h2>\n<p>The inventory number really comes into its own when it is also used as <strong>Barcode or QR code<\/strong> as indicated on the label.
