What this office is for

  • Local field operations

    Pepco crews serving Rockville, Bethesda, Gaithersburg, Germantown and the I-270 corridor stage out of this area. Field staff, not customer counters.

  • Walk-in billing is generally not offered

    Since the 2016 Exelon merger, Pepco has phased out most public bill-pay windows. Pay online at pepco.com, by phone, or at a CheckFreePay agent (CVS, Walmart MoneyCenter).

  • Use the MD line for everything else

    Start, stop, move, billing, payment plans, MEAP, supplier switch: all through 1-800-424-8028 or your My Account at pepco.com.

Insider tip

You can shop for supply in Maryland

Under the Maryland Electric Customer Choice and Competition Act of 1999, every Pepco Maryland customer, including in 20850, can stay on Pepco's Type I residential Standard Offer Service (SOS) or pick a licensed competitive supplier. The MD PSC keeps the official supplier list at mdelectricchoice.com.

Pepco still owns the wires, sends the bill and answers outage calls no matter which supplier you choose. Showing up at a Pepco field address rarely speeds anything up; the supplier switch is handled entirely online or by phone.

Frequently asked questions

Can I walk in to the Pepco 20850 office and pay my bill?
Probably not. Pepco has consolidated most in-person customer service since the 2016 Exelon merger. The fastest free cash option is a CheckFreePay agent: most CVS pharmacies and Walmart MoneyCenters accept Pepco payments at no charge with your bill stub. Always call 1-800-424-8028 first to confirm walk-in hours before visiting.
My power is out in Montgomery County. Should I call the local number?
No. Call the 24/7 state-wide outage line at 1-877-737-2662 (1-877-PEPCO-62) or text OUT to 48710. That feeds the outage map and dispatches the Montgomery County crews automatically. Local addresses are not staffed for emergencies.
I smell gas. Should I call Pepco?
No. Pepco delivers electricity only. Leave the building first, then call Washington Gas at 1-844-927-4427 from a safe distance. Do not use light switches, phones or any electrical device inside the building.
Can I pick a cheaper supplier in Maryland?
Yes. Maryland passed the Electric Customer Choice and Competition Act in 1999 and retail competition opened in 2000. Compare licensed suppliers on the MD PSC marketplace at mdelectricchoice.com. Pepco still owns the wires and bills the delivery portion regardless of who supplies the energy.
