Updated boundaries in the five Maricopa County Board of Supervisors districts and the city of Surprise will require thousands of voters to have new identification cards, officials announced this week.

Maricopa County Recorder Stephen Richer said about 260,000 Maricopa County voters will receive new cards.

“Our office sent roughly 260,000 new voter ID cards to Maricopa County voters impacted by boundary changes, and they should receive those cards sometime this week or next,” Richer said.

“The new ID cards will look exactly like the regular cards but will include a note that indicates the boundary changes.”

Richer encouraged voters to visit BeBallotReady.Vote to check their registration information and view their districts.

The board of supervisors district boundary changes were approved on June 30 and will affect approximately 250,000 voters in Maricopa County. The map   will go into effect in January.

Surprise also updated its district boundaries, effective July 7. About 10,000 people will be affected by the changes, officials said.
