Why only ten digits in every mobile number ?

Answer 1

The same reason there are only 10 digits in any phone number - it's enough and more numbers would be too confusing. Would you want to dial more than 10 numbers when calling someone?

Answer 2

Actually, there are only ten digits in mobile numbers. Mobile numbers (in the US) follow the same NPA/NXX number pattern. In the US, we have our area code (aka and NPA) which is three digits are varies depending on where our mobile number is out of or where we live (if you have a landline). The NXX is a three digit prefix to dialing within that area code so it goes to the right city. Your four digit phone number are the last four digits to get to that specific landline or cell phone. It varies from country to country. In some countries, they have more than ten digits.

One person answered that we have eleven digits here. When you dial a "1" in front of a phone number, it's because you are technically making a long-distance call. Because most (if not all now) cell phone providers supply long distance at no charge, there is no need to dial a "1" before you dial the area code and phone number. Mobile phone systems know where to transfer the call based soley on the area code and seven digit phone number. Also, if you live in an area and want to call another area with the same area code, you don't have to dial the area code along with it. For example, I live in Leavenworth, KS and if I want to call Kansas City, KS, I don't have to dial the area code because the system knows to dial the "913" before it. Now, if I were to call Kansas City, MO, I'd have to dial the "816" because my phone number's area code is "913" so it will try to dial a 913 phone number.

I was visiting family in Ottawa, KS once (whose area code is 785) and my cousin needed to use my phone. She just dialed the number as usual (no area code) and it went to a 913 phone number, not a 785 phone number.

Anyway, the point I am trying to make here is we have ten digits because of the dialing codes in our country. There are billions of people with millions and millions of phone numbers out there. We need that area code because somewhere, in another city, in another state, someone has the EXACT same phone number as you. The only difference is their area code.

Hope this helps.

Answer 3

Presently the ITU (International Telecommunication Union) has decided that ten digits is adequate for any personal phone number using conventional landline, wireless telephone (GSM / CDMA) and satellite telephone (Inmarsat, Thuraya, Iridium). This includes the phone number, and the area code. The country code, when added may increase the phone number to, at best 14 digits. At rate of present expansion of telephone services in these sectors, the union is reconsidering increasing the number of digits to 16 (excluding the country code).

Answer 4

According to my investigation, that number is from Nicaragua, not Albuquerque like I thought because of the 505 area code.
