Here are the basic photo ID requirements set by the legislature and state election officials for registered voters to cast ballots in November. Voters without ID will be allowed to vote in Tuesday's primary.

A voter will need any one of the following:

A Pennsylvania driver's license, either current or expired within the past 12 months.

A non-driver's license photo ID, obtainable from the same PennDot offices that provide driver's licenses, and requiring significant proof of identity.

A valid U.S. passport, not expired.

U.S. military ID, with an expiration date or a designation that the expiration date is indefinite. (For military dependents, the ID must have an expiration date.)

Current photo IDs issued to government employees, including federal, state, county, or municipal workers.

Photo ID cards from "an accredited public or private Pennsylvania college or university," with a specified expiration date that has not yet passed. The state has ruled out ID from most trade schools.

Current photo ID cards issued by "a Pennsylvania care facility, including long-term care facilities, assisted living residences, or personal care homes."

Voters who show up at the polls in November without photo identification deemed valid will be allowed to cast provisional ballots, to be held aside for up to six days. Those voters will have that time to come up with a valid voter ID or otherwise convince county election officials that their ballot should be counted.
