How much does it cost to change my name on my passport?

I am trying to find out the fees for a name change but the website only lists new applicant fees and renewal fees. My passport doesn't expire for 3 more years. I just need to change it to my married name. Any help is appreciated!How much does it cost to change my name on my passport?
If your passport does not expire for 3 more years it has been issued for longer than one year ago; hence you need to apply for a passport renewal using DS-form 82 by post. The application fee is $75 since you do not have to pay the execution fee [$25] for taking an oath again.

If your passport was issued less than a year ago, there is no fee. If it was more than a year ago, the regular passport fee applies. $100 for adults.



There are other documents you need to send, Here is the link.
