What Type of ID Do I Need to Register?

New Mexico’s online registration form requires your New Mexico driver’s license or state ID number and your full Social Security number. The paper form requires your driver’s license or state ID number or the last four digits of your Social Security number. 

If you are registering to vote for the first time in New Mexico and you submit the registration form by mail, you need to include a copy of an ID with your registration form OR include a copy of an ID with your absentee ballot OR present the physical ID at the polls.

The acceptable forms of ID include: (1) an original or copy of a photo identification issued by a government or educational institution; or (2) an original or copy of a current utility bill, bank statement, government check, paycheck, student identification card or other government document, including identification issued by an Indian nation, tribe or pueblo, that shows your name and address. If you present this identification at the polls, the address on your ID is not required to match the address on your certificate of registration.

What Type of ID Do I Need to Vote?

Most New Mexico voters do not need to show ID in order to vote in person at the polls or by absentee ballot. Only first-time voters who registered to vote by mail without providing a copy of one of the above forms of ID will need to present ID before voting. 

If you do not have a valid ID, you may cast a provisional ballot. Your ballot will be counted if you provide a valid ID to the county clerk’s office before 5 p.m. on the second day following the election.

Where Do I Vote?

How Can I Vote?

By Mail

Any registered New Mexico voter may vote by mail starting 28 days before Election Day. No excuse is needed. 

Due to the COVID-19 pandemic, counties have the option to mail absentee ballot applications to all voters. Contact your county clerk’s office for information on their plan.

If voting by mail, your absentee ballot application must be received by October 20. Online requests must be made by 5 p.m. on that day.

  • You may request an absentee ballot by contacting or visiting your county’ clerk's office, filling out an online application, or by mailing or hand-delivering a paper application to your county clerk’s office.

  • To ensure the ballot is returned on time, the state is recommending that voters who are mailing their completed ballots back do so BY NO LATER THAN October 27. If you are running late, it is better to return your ballot in person if you can. Completed absentee ballots may also be returned to the county clerk’s office or any Election Day polling location by 7 p.m. on Election Day.

  • Voters will now be required to put the last 4 digits of their Social Security number on the absentee ballot certificate envelope. Be sure to do this.

Early In-person

Early voting at alternate sites begins October 17 and runs until the Saturday before the election (October 31). Contact your county clerk’s office or visit for locations and times.

Same Day Registration is available at the county clerk’s office through October 31.

Election Day

  • You can cast your ballot at your assigned polling place or any Voting Convenience Center in the county on Election Day.

  • Voting sites will be open from 7 a.m. until 7 p.m. on Election Day. If you are in line by the closing time, then you must be allowed to vote.

Common Questions/Concerns

Registering to Vote Does Not Affect Your:

Federal Financial Aid

Where you register to vote will not affect federal financial aid such as Pell Grants, Perkins or Stafford loans, or your dependency status for FAFSA.

Status as a Dependent on Your Parents’ Taxes

Being registered to vote at a different address from your parents does not prevent them from claiming you as a dependent on their taxes.

Tuition Status

Being deemed out-of-state for tuition purposes does not prevent you from choosing to register to vote in your campus community.


Will registering to vote in New Mexico affect my driver’s license or car registration?

Yes, registering to vote in New Mexico makes you a resident for the purposes of the New Mexico Motor Vehicle Code, so you will be required to get a New Mexico driver’s license and register your car with the New Mexico Motor Vehicle Division.
