Zip code range lookup
If you're actually using Sql Server 2016, you can probably use the new STRING_SPLIT command to create a 'table' to join against.  Just put your comma delimited integers in the STRING_SPLIT command.  Here is an example.

declare @tb_Order table (col1 int, postalcode varchar(5))
insert into @tb_Order values(1,'11111')
insert into @tb_Order values(2,'22222')
insert into @tb_Order values(3,'33333')
insert into @tb_Order values(4,'44444')
insert into @tb_Order values(5,'55555')
---------------------------------------
SELECT a.*
FROM @tb_Order a
JOIN STRING_SPLIT('11111,22222,33333,44444,55555',',')   
    ON convert(varchar(5),value) = a.postalcode;
