 * Hi @[americangear](https://wordpress.org/support/users/americangear/)
 * The UPC codes and MPN codes are typically stored in the `wp_postmeta` table of
   a WordPress database, under the meta key `_global_unique_id`. This can be verified
   by running the following SQL query:
 * `SELECT * FROM wp_postmeta WHERE meta_key = '_global_unique_id';`
 * This query will retrieve all records where the meta key is `_global_unique_id`,
   which often holds UPC or MPN values for products.
 * You can see here – [https://www.awesomescreenshot.com/video/34888478?key=c7e33288f0254674709213cb3ffc27ac](https://www.awesomescreenshot.com/video/34888478?key=c7e33288f0254674709213cb3ffc27ac)
 * If you are still having trouble locating the information, please feel free to
   let me know, and I will be happy to assist you further.
