There is no semantic value in storing it as a number - you won't be doing any numerical operations on it. You should store the value as a string.

---

A mobile number might start with a 0 (zero) therefore I wouldn't advice to store it as a number. My advice would be to store it as a String. Otherwise you should use a long.

---

What about a proper TelephoneNumber type class:

public interface TelephoneNumber
A simple re-usable entity class that defines attributes of a telephone number.

---

You'd better use String, but you can also use long or BigInteger. But using String will allow you to store dashes or spaces between numbers.

---

Mobile numbers uses and E.164 numbering format for telephone or digital communications. You will have to use Strings as valid characters such as "+"/"-" can be found in mobile numbers.

---

Use a String, for for proper semantics I would wrap it in your own MobileNumber class.

Did you have a look at Java's BigInteger? Two possible references are:

• Oracle BigInteger
• Java Notes BigInteger

use Long or String instead of Integer. Or give us some code examples for what you are trying to do.
