LinkedIn Custom URL Rules: 3 Mistakes to Avoid

A LinkedIn custom profile URL can be easier to share than the address assigned when you create an account. LinkedIn has format and availability rules for the part after /in/.

Check LinkedIn’s current formatting requirements before choosing a custom profile URL.

1. Check the 3–100 character limit

The very first rule of a LinkedIn vanity URL is its length constraint. Your custom identifier must be between 3 and 100 characters long.

You cannot register a two-character vanity URL (like linkedin.com/in/ab or /in/j9). LinkedIn’s current profile URL help gives a 3–100 character range. A shorter version of your name or professional brand is often easier to say and type; test the final link before printing it.

2. Avoid spaces and special characters

LinkedIn’s current help says a custom URL should not contain spaces, symbols, or special characters. Start with a readable variation of your name or professional brand. If you want to use punctuation, test the exact spelling in LinkedIn’s URL editor rather than relying on a third-party format summary.

3. Check non-ASCII spelling in the editor

If your name contains an accent or uses another script, check the exact candidate in the current editor. A plain-letter transliteration may be easier to dictate, but keep the spelling you want people to see in your profile name. The published help does not explain every account-specific rejection.

Frequently Asked Questions (FAQ)

Can I include the word "LinkedIn" in my custom URL? LinkedIn’s current URL rules say the custom part cannot contain “LinkedIn.” Choose a variation of your name or professional brand.

Why is my URL unavailable if nobody is currently using it? A LinkedIn handle checker can be inconclusive, so confirm the exact name in LinkedIn’s settings. LinkedIn’s current URL guidance says a previous custom URL normally stays linked to its owner for six months after a change unless they unlink it; the unlinked name has a different waiting period. An account closure also has its own timeline. Availability therefore depends on how the old URL was released.

Can I use capital letters to make it easier to read? LinkedIn says the custom part is case-insensitive: JohnSmith and johnsmith point to the same profile. Capitalization is a display choice, not a way to claim another URL.

After saving a change, open the new profile URL and update links you control.
