On a related note, competing domain name companies will send you bogus or deceptive domain name renewal notices. Clients ask about these emails that appear to be legitimate renewal notices all the time.
OK, these bogus domain name renewal company notices are probably skating within the letter of the law…but they’ll write you a letter asking you to renew your domain name with them and it won’t be clear that they are asking you to “switch” your domain registration from your current register to them. So memorize the name of your domain name company or put the record where you can find it in seconds and save yourself confusion.
If this does happen to you, don’t worry. It doesn’t really cause a problem. If you discover you are now registered with a company you don’t recognize, simply switch back to a major domain name company like godaddy.com.
