There are nearly six million registrants for the May 2022 polls.
On Twitter, Commission on Elections (Comelec) Commissioner Rowena Guanzon said there are already 5,727,223 new registrants as of August 13.
She said more voters may be able to vote in the next elections if deactivated voters will reactivate their registration records.
"If only 50 percent of deactivated voters of 6.3 million will be reactivated, we can hit 8,877,233 voters," Guanzon said.
Last month, Comelec Spokesperson James Jimenez said the return of Metro Manila to a state of enhanced community quarantine (ECQ) will have an impact on voter registration numbers.
However, the poll official pointed that they have already exceeded their projection.
"It bears remembering that the Comelec has, in fact, already exceeded expectations for voter registration during a pandemic," Jimenez said in a statement.
"More than 4 million newly eligible voters are already included in the voter rolls, and we have already blown past earlier and lower projections of the total number of voters registered for the 2022 National and Local Elections," he added.
Voter registration is currrently suspended in areas under enhanced community quarantine (ECQ) and modified ECQ.
The voter registration period will end on Sept. 30.
