With Global Model Number, you can uniquely identify a product model through the entire product life cycle from design to production, procurement, use, maintenance, and removal.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-who-uses-gmn\">Who uses GMN?<\/h2>\n\n\n\n<p>GMN can be used on products sold in different versions but which are technically the same product, for example, the product may have a different color or size. Another area is medical equipment where GMN meets EU requirements according to EU <a data-type=\"page\" data-id=\"6317\" href=\"https:\/\/gs1.se\/en\/your-industry\/healthcare\/udi-unique-device-identification\/\">Unique Device Identification (UDI)<\/a> for identification and marking of medical devices and In-Vitro diagnostics.

There may also be a need to launch different products based on the same technical product specification. Then there may be a need to group them under a same product family with a GMN.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-use-gmn\">How to use GMN<\/h2>\n\n\n\n<p>Initially, GMN is used to identify product models or product families and medical equipment according to two EU regulations \u2013 Medical Devices Regulation (MDR) AND In-Vitro Diagnostics Regulation (VDR).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-frequently-asked-questions-about-gmn\">Frequently Asked Questions about GMN<\/h2>\n\n\n\n\n<section class=\"block-accordion full-width-2 py-6 gs1-background-color-ui-1\">\n  <div class=\"container\">\n    <div class=\"row m-0\">\n      <div class=\"col-12 col-md accordion p-0 bg-white mb-4 mb-md-0\">\n                  <div class=\"row m-0\">\n\n            <a href=\"#\" class=\"col col-12 collapsed p-0 text-decoration-none\" id=\"heading-1\" data-toggle=\"collapse\" data-target=\"#collapsg-1\" aria-expanded=\"true\" aria-controls=\"collapsg-1\">\n\n              <span class=\"btn-expand px-4 w-100 text-left d-flex \" type=\"\">\n\n                <div class=\"pr-4\">\n                  <h6 class=\"mb-0\" id=\"1\">How is a GMN created? <\/h6>\n                <\/div>\n\n                <svg width=\"1em\" height=\"1em\" viewBox=\"0 0 16 16\" class=\"bi bi-chevron-down ml-auto w-18px flex-shrink-0\" fill=\"currentColor\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n                  <path fill-rule=\"evenodd\" d=\"M1.646 4.646a.5.5 0 0 1 .708 0L8 10.293l5.646-5.647a.5.5 0 0 1 .708.708l-6 6a.5.5 0 0 1-.708 0l-6-6a.5.5 0 0 1 0-.708z\" \/>\n                <\/svg>\n              <\/span>\n\n            <\/a>\n            <div id=\"collapsg-1\" class=\"collapse col col-12 p-0\" aria-labelledby=\"heading-1\">\n              <div class=\"card-body\">\n                <p>A GMN consists of three components: the GS1 Company Prefix, the Model Reference, and a mandatory pair of Check Characters.<\/p>\n<div>\n<ul>\n<li><strong>GS1 Company Prefix:<\/strong> When you become a GS1 customer, you automatically receive a GS1 Company Prefix.
