SQL-Server-2012

Hello Experts

I have a table which has about 11000 row. There is a column named Account which varchar(12) And the last 8 digit starts from 1 and now arrived to 21045.

Now I am going to insert 2000 row in this table using a select statement and I want to find the gaps.

How can I find the gaps?

Why do you care about IDs? This is typically handled by the database engine which will know how to reuse gaps when it needs them.
Ideally primary keys shouldn't even be presented to users. There is no point in trying to maintain 'by hand' an identity field.
