The Republican-controlled Legislature voted earlier this year to require each voter to show a driver's license or other photo ID at the polls.
The requirement can become law only if it receives federal approval. The Justice Department has rejected ID laws from Texas and South Carolina in recent months, amid concerns that they would dilute minority voting strength.
The Mississippi bill says anyone without proper identification can get a state-issued photo card at no cost, but no money was set aside to make them.
Republican Hosemann says Monday that he's asking people to let his office know if they need ID.
