क्यों भारत के हर मोबाइल नंबर से पहले लगता है +91?

+91 यह वो कोड (India Mobile Number Code) है जो हर भारतीय मोबाइल नंबर के आगे लगा दिखता है

इसी तरह, अमेरिका का देश कोड +1, यूनाइटेड किंगडम का +44 और चीन का +86 है

[{"selector":"#anim-f34d2d61-7aa3-4aa7-8cce-8ebe03abf4ee","keyframes":{"opacity":[0,1]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-4748d6d5-64e6-4d1e-836b-26241531cbd3","keyframes":{"transform":["translate3d(0px, 141.16707%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

बिना देश कोड के, अंतरराष्ट्रीय कॉल संभव नहीं है

[{"selector":"#anim-16e7719b-87f0-4f73-9e7c-86c2d79129dc","keyframes":{"opacity":[0,1]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-f1fd4f7d-25f3-4574-9690-3589086792fd","keyframes":{"transform":["translate3d(0px, 185.94101%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-00568eec-9b0c-4ad6-8fc6-e31483f83d7f [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(21.141699041261532%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}]

देश कोड की शुरुआत 1960 के दशक में हुई थी, जब अंतरराष्ट्रीय कॉलिंग को व्यवस्थित करने की जरूरत महसूस की गई

[{"selector":"#anim-76c8d5b7-6411-41c9-aeca-50256637bcc5","keyframes":{"opacity":[0,1]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-8905280a-36a3-4893-8585-c4752304b809","keyframes":{"transform":["translate3d(0px, 125.66019%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-f5775bcb-1836-4fa8-831f-1f43eba0316b [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(3.7976255940630175%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

उस समय, दुनिया भर में टेलीकम्युनिकेशन नेटवर्क तेजी से बढ़ रहा था, और अलग-अलग देशों के बीच कॉलिंग को सुव्यवस्थित करने के लिए एक मानक प्रणाली की आवश्यकता थी

[{"selector":"#anim-aa50fcbb-2f2e-42d7-a30c-0411f88e840f","keyframes":{"opacity":[0,1]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-ea7b6803-8eb9-4406-ac12-ed621c0408a8","keyframes":{"transform":["translate3d(0px, 118.90331%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-ed4ae405-ae1f-4213-8fee-44898ef9bfb3 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

ITU ने इसके लिए देश कोड की प्रणाली विकसित की, जिसमें हर देश को एक अलग कोड दिया गया। भारत को +91 का कोड आवंटित किया गया

[{"selector":"#anim-c1f47c27-b304-4680-a408-6d283c094d89","keyframes":{"opacity":[0,1]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-d0ac6464-9980-4f37-b548-d9fb860a0e57","keyframes":{"transform":["translate3d(0px, 121.97065%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]
