Earlier this month, the Department of Labor and Industry’s Unemployment Compensation (UC) Service Centers transitioned to a new phone system.As a result, claimants may no longer hear a busy signal when phone lines are full. Instead, claimants may hear a default message from the individual’s phone carrier (Verizon, AT&T, Sprint, T-Mobile, etc.).Please be aware that the UC Service Centers are able to take calls and the system is functioning. If you receive one of these messages, please try again. UC call center hours are Mondays, Tuesdays and Thursdays from 8 a.m. to 4 p.m., and Fridays from 8 a.m. to noon. Claimants are also encouraged to visit uc.pa.gov to create a new claim or check on the status of an existing claim.
