Less than a week after going live, New Jersey has added 21,352 new voters through online voter registration.
New Jersey began online registration on September 4, becoming the 41st state to offer a paperless option.
Gov. Phil Murphy signed legislation in January to allow eligible New Jerseyans to register online using a state Motor Vehicle Commission identification or the last four digits of their social security number along with a digital signature.
About 53% of the newly-registered voters used their drivers license and 47% opted to give their social security numbers.
The bill was sponsored by Senate Majority Leader Loretta Weinberg and Assemblywoman Gabrielle Mosquera (D-Gloucester Township)
Arizona has had online voter registration since 2002.
The deadline to register to vote for the November general election is October 13.
