It is very important to know the UDID of your iPhone. UDID is basically a 40-character alphanumeric string \u2013 especially on iPhone X models or prior or a 24-character identifier with a dash after the 8th digits on iPhone X5 or subsequent models. Whereas for an older model, grabbing the UDID is simple.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It&#8217;s pretty simple to track down your <strong>UDID<\/strong>. You have to launch iTunes from your iPhone, click on the Summary tab, then select the serial number and it changes to the UDID number. According to the revelation from Wall Street Journal, the apps often send your UDID to several databases without your knowledge and since then the privacy of app usage has been in the spotlight. The UDID was freely available to developers until the release of <a href=\"https:\/\/support.apple.com\/en-ca\/HT212597\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><strong>iOS 5<\/strong><\/a>, but Apple warned that after iOS 5.1 was released, they&#8217;d start rejecting apps that collected this number.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-easy-steps-to-follow-to-get-your-udid-on-iphone\"><strong>Easy Steps to Follow to Get Your UDID<\/strong> on iPhone<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you\u2019re still looking to know your UDID, here\u2019s what you need to do to get the UDID number on <a href=\"https:\/\/en.wikipedia.org\/wiki\/IPhone_X\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><strong>iPhone X<\/strong><\/a>, iPhone 8, iPhone 8 Plus.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Launch the iTunes.<\/li>\n\n\n\n<li>Under Devices, click on your device.<\/li>\n\n\n\n<li>Next, select the \u201cSerial Number.\u201d Doing this will change the Serial Number into the UDID.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This process has changed though and is a bit more involved now for the iPhone XS series. Retrieving the UDID on newer iPhone XS devices is still relatively simple, you just do not need to use iTunes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"
