Why Do They Want My Email Address Twice?

I can understand typing passwords twice, but...

I've seen a lot of website registration forms that requires me to type my email address twice:

Email Address (required):
Retype Email Address (required):

Why is this? Who invented this practice? Does it work (for whatever reason it is invented for)?

Are you annoyed by this practice? I am.

Have you designed such a registration form yourself? Why did you decide to do it? (Not counting "Everybody was doing it?")

Weiqi, I noticed that as well. It is mostly used in registration/signup pages. I do not know the exact rational behind it, but, is it to ensure the user typed in an email address that the user intends to, especially when the email address is going to be used as the user id?

Re: Why Do They Want My Email Address Twice?

Do you ever write an application to ask the user's password twice? Why did you do that? It is for the same reason. They want to make sure there are no typos. I get very annoyed when there is an "Add Comment" button on the screen, but it doesn't allow you to click on it. Very annoyed.

I'm annoyed too. It's brought to you by the wonderful rules of CSS. I'm learning my CSS, floats, layouts and positioning as fast as I can to address the issue. A workaround is to use the tab key to navigate to the button and then press the space bar.

Thanks for pointing this out. I've noticed the same problem on the authoring screens and didn't realize that user screens are also affected.

Re: Why Do They Want My Email Address Twice?

Well, the main difference is that password fields are obscured, so you can't exactly _look_ at what you've typed to be sure it's valid. I'm happen to not be blind, so I have a way to verify what I've typed...

Re: Why Do They Want My Email Address Twice?

The same reason why they ask you to retype your password.

Re: Why Do They Want My Email Address Twice?

But there is a difference between passwords and email addresses. Usually, the password you typed is not echoed on the screen. So the psychology of the second password request is like "OK, you've just made up a password for me. Let me see you type it in again just to make sure you remembered it right."

The same thing cannot be said of the email addresses because they are echoed back on the screen. Even if there is merit to the double request of email addresses, the question remains "Why email addresses?" And indeed, why not make the user type in the login name twice just to make sure it is entered right? Why not make the user type everything in twice?

Re: Why Do They Want My Email Address Twice?

I am actually grateful that websites started this practice since it prevents me from giving the wrong address by mistake.

Re: Why Do They Want My Email Address Twice?

Because email addresses are are the primary identifier in most of these online systems.

I didn't say it was a good idea -- just that that's why they do it.

A much better solution is to use a separate confirmation channel. E.g., send a confirmation email to the address which requires either an email reply or a web response (confirmation page or code). This has the added benefit of knowing that the email address is actually valid and connected to that user (rather than being any random address).

Re: Why Do They Want My Email Address Twice?

thanks for mentioning this annoyance. i would like to ask another questio. how many times you just copied and pasted the first email entry to the latter? ;)

Re: Why Do They Want My Email Address Twice?

I always copy and paste when asked to do this. That, or use AutoFill. Redundancy for nothing other than the sake of redundancy is one of my biggest pet peeves.

Re: Why Do They Want My Email Address Twice?

I always build pages that ask for customers to confirm their email. But I make the second field optional.
