<p>Normally it is not possible to have a page slug (the page’s name in the URL) that is a number. For example this will not work: <code>yoursite.com/about/2/</code>. That URL conflicts with paged content feature where you can posts and pages with multiple pages of content by adding <code></code> within your content.</p>
<p>This plugin allows you to have pages with numbers as slugs by giving up the ability to have paged content pages which isn’t a big deal as most people don’t use paged content pages anyway.</p>

Allow Numeric Slugs

Works with 5.2.2

Allows Pages to have a slug (URL) that is only a number. Sacrifices the paged content ability in Pages to accomplish it.

<p><a href="https://squaredaway.studio/wordpress-plugin-enable-numeric-slugs/" rel="nofollow ugc">Enable Numeric Slugs</a> plugin fixes postname(slug) can not be a 4 digit number issue on wordpress 4.9.1. As a matter of fact, its not a bug, wordpress reserve 4 digit number in url for yearly archive. I just simply remove the rewrite rules stored in MySql. If you want to reset to orignal rewrite rules, go to Permalink Settings and Save Changes. That’s it..</p>
