Friday is the last day for Oklahomans to register to vote in the Nov. 5 election.

Misha Mohr, a spokesperson for the State Election Board, said there has been a surge in the number of people in Oklahoma registering to vote after National Voter Registration Day last month. The National Day event aims to raise awareness of voter registration options, hoping to help people sign up who might not otherwise do so.

Since September 30, Oklahoma has added more than 12,000 voters to its voter rolls and seen an increase in the number of people updating or deleting their registrations. Currently, more than 2.43 million Oklahomans are registered to vote. The state does not keep statistics on how many people are eligible to vote but have not registered.

“All of our county election boards have seen a surge, and they are still processing voter registration applications,” Mohr said.

She said she could not speculate on the reason for the last-minute increase.

Mohr also said election officials recently sent postcards to voters who may have had a change of address to remind them to update their registration.

“We see people updating or even deleting their registration if they haven’t done so,” Mohr said.

All voter registration applications must be postmarked or received by Oct. 11, she said.

Oklahomans can register to vote through the online voter portalbut must have a valid driver’s license or ID card that matches the address a person intends to use for registration.

They can also register with their local tag agency, but must ensure the application is stamped with the filing date.

In-person early voting begins October 30 and runs through November 2. Early voting hours are 8 a.m. to 6 p.m. weekdays and 8 a.m. to 2 p.m. on November 2.
