Just because you have a marriage license with your new last name, doesn't mean you've officially changed your name. (If you thought the wedding was the hard part, wait until you see the lines at the social security office and DMV.)
Rather do it the old-school way? Follow these steps:
1. Get your marriage license.
Before you can change your name, you'll need the original (or certified) marriage license with the raised seal and your new last name on it. Call the clerk's office where your license was filed to get copies if one wasn't automatically sent to you.
2. Change your Social Security card.
Visit the Social Security Administration's website and fill out the application for a new Social Security card. You'll keep the same number—just your name will be different. Mail in your application to the local Social Security Administration office. You should get your new card within 10 business days.
3. Change your license at the DMV.
Take a trip to the local Department of Motor Vehicles office to get a new license with your new last name. Bring every form of identification you can get your hands on—your old license, your certified marriage license and, most importantly, your new Social Security card.
4. Change your bank accounts.
This one's a biggie, especially if you're setting up a joint bank account, or if you have one already set up. The fastest way to change your name at your bank is to go into a branch location, bringing your new driver's license and your marriage license. You should request new checks and debit and credit cards on top of changing the name attached to your accounts. Something to note: You might get hit with fees for requesting a new debit card.
5. Fill in the blanks
Once you have a social security card and driver's license in your married name, other changes should be easy. Some places only require a phone call; others may ask for a copy of your marriage certificate or social security card. Be sure to notify:
