How To Tweak Digit Length

I have a bigINT column in SQL server where the digit length is 14. How and where can I tweak the digit length in SQL Server 2008. Would like this system created bigint column to default to 10 digits.

You can convert it to varchar and truncate the digits
select left(cast(yourcol as varchar), 10)
or you can divide the bigint number by 10000
select yourcol / 10000
If that's not what you want, please clarify with an example

If you want a specified number of digits, choose a DECIMAL column.   In SQL Server, a BigINT column is an 8-byte integer, which is good to 14 digits.

Alternately, you could apply conditions on the row to only allow values between 1000000000 and 9999999999, so other values would return errors.
When you say "system created" do you mean you told it to create a new column called "X" and just took the default of bigINT or are you talking about some system column?

If you mean you have a bigint IDENTITY column, then a number cannot be definition have leading zeroes.
However, you can force it to start at 1 billion which is the smallest number with 10 digits.
You can reseed the identity using something like this

create table xy (i bigint identity(1,1), other varchar(10))
dbcc checkident(xy, reseed, 1000000000)
