   Getting Current Pagination Number

   
   <?php $paged = get_query_var( 'paged', 1 ); ?>
   
   <h1><?php printf( esc_html__( 'Currently browsing page %s', 'textdomain' ), $paged ); ?></h1>
   

   For getting the current pagination number on a static front page (Page template) you have to use the page query variable:

   
   <?php  $page = get_query_var( 'page', 1 );  ?>
   <h1><?php printf( esc_html__( 'Currently browsing page %s on a static front page', 'textdomain' ), $page ); ?></h1>
   

   Note: The query variable page holds the pagenumber for a single paginated Post or Page that includes the <!--nextpage--> Quicktag in the post content.
