Representing Phone Numbers: String vs. Numeric Types

When storing a mobile number in your application, consider whether an integer class would suffice or if a string is more appropriate.

Integer Storage

If you attempt to store phone numbers as integers, doubles, or longs, you may encounter unexpected results. Leading zeros can be lost, and calculations may yield inaccurate values.

String Storage

Using a String to represent phone numbers is generally the preferred approach. Strings allow you to:

• Store leading zeros intact
• Preserve any dashes or spaces entered for readability

Numeric Storage Considerations

If using a numeric type is essential, consider:

• Long: Can store up to 10 digits, but loses leading zeros.
• BigInteger: Can handle larger numbers, but may not be necessary for phone numbers.

However, strings remain the more versatile and recommended option for phone number storage, especially considering their ability to preserve formatting and facilitate readability.
