Yes.

Nevada officials verify signatures on mail ballots to ensure they match with a voter's file.

Under Nevada law, election officials use an electronic device to determine whether the signature on the mail ballot matches the voter's registration record. If it does not, the signature is then checked manually against all of the voter's signatures on record.

If there is a "reasonable question of fact" regarding the validity of the signature, election officials are required to contact the voter and allow them to provide confirmation or another signature.

In recent election cycles, thousands of ballots have been invalidated because a voter did not fix their signature. In the state's 2026 primary, about 2,000 signatures were not fixed, while the state tossed out 9,000 ballots in the 2024 general election because of invalid signatures.
