text-lg">What is a UUID?</h3><div class="text-sm"> <p class="mb-3"> UUID is an acronym for 'Universally Unique Identifier'. It is a 128-bit integer number used to identify resources. The term GUID is generally used by developers working with Microsoft technologies, while UUID is used everywhere else. </p></div></div><div class="space-y-2"><h3 class="font-semibold text-lg">How unique is a GUID?</h3><div class="text-sm"> <p class="mb-3"> 128-bits is big enough and the generation algorithm is unique enough that if 1,000,000,000 GUIDs per second were generated for 1 year the probability of a duplicate would be only 50%. Or if every human on Earth generated 600,000,000 GUIDs there would only be a 50% probability of a duplicate. </p></div></div><div class="space-y-2"><h3 class="font-semibold text-lg">Why use an online UUID generator?</h3><div class="text-sm"> <p class="mb-3"> Most programming languages have a simple way to generate UUIDs. But, sometimes you might just need a single UUID and do not want to write any code. </p></div></div></div></div></div></main></div></div><script id="__NEXT_DATA__" type="application/json">{"props":{"pageProps":{"data":{"title":"UUID Generator","short_description":"Create multiple universally unique identifier (UUID)","path":"utilities","url":"uuid-generator"},"params":{"category":"utilities","slug":"uuid-generator"}},"__N_SSG":true},"page":"/[category]/[slug]","query":{"category":"utilities","slug":"uuid-generator"},"buildId":"Obl_egUjMNSehDA0y3EYc","isFallback":false,"gsp":true,"scriptLoader":[]}</script></body></html>
