Friday is the last day to register to vote in New York.

If you want to vote in the Nov. 8 presidential election, here are three ways to register. Check here if you aren't sure whether or not you're registered.

Online

-If you have a New York State ID, you can register on the Department of Motor Vehicles website, using its online Voter Registration Application. The DMV will forward the form to your county Board of Elections for processing.

By mail

-If you don't have a state ID, go to the New York Board of Elections website to download the Voter Registration Form.

-You can either fill out the form online or after you print it, but you must sign it once it's printed. Send the completed form to your county's Board of Elections address. The addresses are listed on the second page of the document.

-The form must be postmarked by Oct. 14 in order to be processed for the election. 

-You can also update information, such as your address, with the same form. 

In person

-You can also register at your county's Board of Elections office (addresses here), a DMV center or the offices of one of these agencies.
