WordPress is the backbone of countless websites worldwide. Its flexibility is largely due to various features, including the Media Library. This is a user-friendly tool for managing various media files. Within this library, every file is assigned a unique identifier known as an attachment id.

Understanding the functionality of the media library and attachment ids can be a game-changer in managing your website more effectively, especially when dealing with a large volume of media files. 

This article is a comprehensive guide to understanding and finding these attachment ids in WordPress.

Whether manually locating an id or using a plugin to assist you, knowing how to find attachment ids will streamline your administrative tasks and make your WordPress experience more efficient. 

So let’s start learning about the WordPress Media Library and attachment ids.

Understanding the WordPress Media Library and Attachment Ids

The WordPress Media Library is an integral part of any WordPress website. It's a powerful tool for storing and managing all your media files, including images, videos, audio, and documents. 

It provides a centralized location to upload, edit, and delete media files in your posts and pages. 

How WordPress Organizes and Identifies Media Files

Once a media file is uploaded to the WordPress Media Library, WordPress systematically organizes these files.

Each file is given a unique attachment id. WordPress uses this numerical identifier to track and retrieve the file.

This id is assigned automatically upon upload and is stored in the WordPress database. This organization strategy allows WordPress to quickly locate and display the correct media file when needed, whether it's being shown on a post, a page, or a custom post type.

By default, the attachment id is not shown to website visitors. As the site owner, there are times when you may need to find this id for specific tasks or troubleshooting. In the following sections, we’ll show you how to locate these ids manually and with a plugin.

Here are a few scenarios when knowing what the specific Attachment ids of your files may come in handy:

  1. Customizing Website Features: Some themes and plugins require attachment ids to customize certain features. For example, you might need an image's attachment id to set it as a featured image or to include it in a slider.
  2. Programming and Development: If you’re getting into the more technical side of WordPress, you should use attachment ids in your code. For example, developers use these ids when creating shortcodes, custom queries, or tweaking theme files.
  3. Troubleshooting: Attachment ids can also be helpful when troubleshooting. If a specific media file is causing issues, finding its attachment id can help you locate it quickly in the Media Library for inspection or removal.

In the upcoming sections, we'll explore the various methods you can use to find these attachment ids in WordPress.

Manual Method of Finding Attachment IDs

To find attachment ids manually, you must first access the Media Library from your WordPress dashboard's left-hand menu.

In the Media Library, you will see a list or grid (depending on your view setting) of all the media files that have been uploaded to your WordPress website.

To find the attachment id of a media file, click on the file's name or thumbnail to open its Attachment Details window.

Once the Attachment Details window is open, look at your browser's address bar. You will see a URL that ends with post=1234, where 1234 is the attachment id of the media file. This number is WordPress's unique identifier assigned to that particular file.

Common Issues in Finding Attachment Ids

You may encounter some issues when trying to find attachment ids in your WordPress site. 

Here are a few common problems and solutions to these problems:

Can't Find the Attachment Id in the URL

Sometimes, when you open a media file's Attachment Details" you might not see the post=1234 part in the URL. This could be due to various reasons like certain WordPress configurations or specific admin themes that alter the URL structure.


If you can't find the attachment id in the URL, you might need to use a plugin to reveal the ids. Try installing one of the plugins mentioned above.

The Plugin Isn't Working

You've installed and activated a plugin that's supposed to reveal attachment ids, but it's not doing its job for some reason. This could be due to a plugin conflict, or the plugin might not be compatible with your version of WordPress.


If a plugin isn't working, try to deactivate and reactivate it first. If it still doesn't work, it could conflict with another plugin. Deactivate your other plugins individually to see if that solves the problem. 

If this doesn’t work, the plugin might not be compatible with your WordPress version. Either update WordPress or look or choose another plugin to install. 

Slow Website After Plugin Installation 

After installing a plugin to reveal Attachment IDs, you notice that your website has become slower. This could be because the plugin needs to be better coded or your website has too many plugins.


If your website is running slow after installing a plugin, try deactivating the plugin and see if that speeds things up. If it does, you should find a more lightweight plugin or one that's better coded. 

Also, review your website to see if there are any other plugins you can deactivate. Remember, it's best to keep your plugins to a minimum to ensure optimal website performance.

Solutions and Tips to Overcome These Issues

Remember, troubleshooting is part and parcel of managing a WordPress website. Keep going even if you encounter problems. With a little patience and perseverance, a solution will always be found!
