Yes, you can change your National Car Rental username, but it's not a straightforward DIY process you can do within your online account settings. For reasons, you must contact National Car Rental's customer service directly to request this change. The most efficient way is to call their dedicated support line. Be prepared to verify your identity by providing information such as your full name, current email address, and details from a recent rental agreement.
The primary reason you cannot change it yourself online is that your username is typically your primary email address. This email is the unique identifier for your Emerald Club loyalty account, which is tied to your entire rental history, preferences, and points balance. Altering this core identifier requires manual verification by a support agent to prevent fraudulent account access.
Here’s a quick comparison of the methods available:
| Method | Steps Involved | Estimated Time | Best For |
|---|---|---|---|
| Phone Call | Call 1-888-826-6890, verify identity, request change. | 5-15 minutes | Immediate change, complex issues. |
| Online Form | Fill out a contact form on National's website, wait for email reply. | 24-48 hours | Non-urgent requests, detailed explanations. |
| Live Chat | Initiate chat via website, agent will likely escalate to phone. | 10-20 minutes | Quick initial inquiry, but may not resolve fully. |
After the agent processes your request, you will receive a confirmation email. You will then use your new email address as your username for all future logins. If you're changing your username because you've lost access to the old email, it's crucial to mention this specifically to the agent, as the verification process might be more stringent.

Just get on the with them. I had to do it last year when I got a new work email. You can't just click a button on the website. I called the main Emerald Club number, answered a few security questions about my last rental, and the guy on the phone had it sorted in under ten minutes. Got a confirmation email at my new address right after we hung up. Way easier than trying to find some hidden setting online.

As a frequent renter, my advice is to consolidate your travel accounts under one primary email. If a username change is necessary, understand that National's system links your username directly to your Emerald Club profile for . The process is intentionally manual. Have your driver's license and Emerald Club number ready before you call. This preparation ensures the customer service representative can verify you quickly and update the account record without delay, minimizing any disruption to your status or points.

Before you call, check if you really need to change the username itself. Often, people just want to update their contact email or password, which you can do in your account settings. Your username is your key identifier. If it's absolutely necessary, the direct line is your best bet. Be patient and have your information handy—it’s a step that protects your account and rental history. The short call is worth the long-term peace of mind.

Yeah, I went through this. The website doesn't let you do it, which is kinda annoying. You have to call. I dug up an old rental confirmation PDF to have my contract number ready, which helped a lot. The customer service lady was super helpful; she asked for my new email, sent a test message to it while I was on the line, and had me confirm the code. Whole thing was done in maybe seven minutes. Just be ready to prove you are who you say you are.
