If two first numbers exist in wp_meta_query value

You could try to use the REGEX compare option for the meta_query, like so:

 'meta_query' => array(
        array(
            'key'       => 'company_address_zip_code',
            'value'     => '^29@',
            'compare'   => 'REGEXP',
        )
    )
