Doubt about setting size for table fields!

Question

Hello! Follow the following code:

create table Pessoa (
   codigo_pessoa int not null primary key,
   nome nvarchar(50) not null,
   data_nascimento date not null,
   cpf int(11) not null
)

In the field of Cpf, set a size for it. However, it returns the following error: cannot specify a column width in the int data type. The int typing does not allow setting the size of the field. It is so or have some syntax error?

To solve this, I created the table this way:

create table Pessoa (
   codigo_pessoa int not null primary key,
   nome nvarchar(50) not null,
   data_nascimento date not null,
   cpf int not null
)

And I ran an Insert on this table:

insert into Pessoa (codigo_pessoa, nome, data_nascimento, cpf)
            values (1, 'João Silva', '20/02/1997', 03188888801);

However, it returns this error: Arithmetic overflow error when converting Expression to int data type. Cpf is larger than the respective field, I suppose. What happens to this Cpf field? Does anyone have any idea? Grateful for the attention!
