Elections officials in Maricopa County, Arizona, say they have been working to contact 7,000 early voters in recent weeks by phone and e-mail to confirm signatures on their ballots. 

Those signatures must be verified by 7 p.m. Tuesday or their ballots don’t count, said Elizabeth Bartholomew, executive assistant at the Maricopa County Elections Department. 

Approximately 2,000 ballots received by elections officials had no signature, and voters who sent in those ballots are required to report to elections officials at their polling place or main County Election Office. 

Some 5,000 ballots had signatures but were in question, because they did not match those on record with their County Elections Department voter registration form. 

The 5,000 voters have been contacted by phone, e-mail and mail, Bartholomew said. Voters contacted by phone could verify their identity/verify their signature by giving their date of birth, address, or social security number, said Bartholomew. 

Voters who did not sign their ballot needed to resolve the issue by going to their polling place before the polls close at 7 p.m. or going to the County Election Department Office, also known MCTEC Office.
