Never try to store phone numbers as an int or any other kind of numeric data type. You can't do arithmetic on them, and while 007, 07 and 7 are the same number they are not necessarily the same phone number - in some countries a leading 0 is significant and forms part of the number itself (see A leading zero in numbers formatted for domestic usage can always be discarded when dialing from abroad). Moreover, a phone number may contain other diallable characters (see Phone numbers contain only digits) or an extension portion, dialled after waiting for a tone.
Tip: Use the library to parse and format numbers to handle this correctly for every country.
Thanks for your mail.
- smallint will be out of range for this due to number of bytes and ideally its behaving same way as any ***int data type.
- Boolean is not possible as this is phone number.
Please suggest

Subject: Re: Data Type to store Leading Zero(0)
Use datatype smallint(1) for storing zero or use Boolean datatype.

Hello Experts,
As per business needs we need to store Zero(0) in primary key column of table with this kind of value à 07******** with applications written in Java microservices.
We are not able to use numeric data type as it trims the Zero value in leading, but it’s also a performance impact if we define varchar in the data type.
Please suggest.
Thanks
