MEI Kya Hota Hai?
IMEI ka poora naam hai International Mobile Equipment Identity. Yeh ek 15 digit ka unique number hota hai jo duniya mein har mobile phone ko alag pehchaan deta hai.
Seedhi baat:
Jis tarah har insaan ka CNIC number alag hota hai usi tarah har phone ka IMEI number alag hota hai.
Duniya mein koi bhi do phones aisa nahi hain jinka IMEI number same ho yeh ek guaranteed unique identity hai.

Tarika 4 : Battery Se (Purane Phones): Purane phones mein battery nikaalein IMEI number andar printed hota tha.
MEI Number Ki Structure Yeh Banaa Kaise Hota Hai?
IMEI sirf random numbers nahi hote iska ek poora system hota hai. 15 digits ko 4 hisson mein divide kiya jaata hai:
1. TAC Type Allocation Code (Pehle 8 Digits)
Yeh phone ke manufacturer aur model ko identify karta hai. Matlab sirf pehle 8 digits se pata chal jaata hai ke yeh phone Samsung ka hai, Apple ka hai, ya kisi aur company ka.
2. Serial Number (Aglay 6 Digits)
Yeh usi manufacturer ke ek specific phone unit ko identify karta hai. Factory mein jab phone banta hai toh use yeh unique serial number diya jaata hai.
3. Check Digit (Aakhri 1 Digit)
Yeh verification digit hota hai. Iska kaam yeh verify karna hai ke poora IMEI number sahi hai ya nahi. Yeh Luhn Algorithm ke zariye calculate hota hai ek mathematical formula jo batata hai ke number genuine hai.
IMEI Kaise Kaam Karta Hai? Network Ka Role
Yahan woh hissa hai jahan IMEI asli kaam karta hai:
Jab Aap SIM Card Lagate Hain
Jab aap apne phone mein SIM lagaate hain aur network se connect hote hain toh yeh hota hai:
- Aapka phone network tower se rabta karta hai
- Phone apna IMEI number network ko bhejta hai
- Network company is IMEI ko apne EIR (Equipment Identity Register) database mein check karti hai
- Agar IMEI valid hai connection allow ho jaata hai
- Agar IMEI blacklist mein hai connection block ho jaata hai
EIR Teen Qisam Ki List
Telecom companies ek special database rakhti hain jisme teen lists hoti hain:
White List: Yeh woh phones hain jo bilkul sahi aur registered hain. Inhe network use karne ki izaazat hoti hai.
Grey List: Yeh woh phones hain jine monitor kiya ja raha hota hai shayad koi issue ho lekin ban nahi hua.
Black List: Yeh woh phones hain jo chori shuda ya kisi wajah se ban kiye gaye hain. Inhe network access nahi milta.
IMEI Ka Faida Yeh Itna Zaroori Kyun Hai?
