To find your Maryland representatives by ZIP code, start with the ZIP but be ready to enter your full street address. ZIP codes don’t line up with political district boundaries, so a ZIP-only search often returns the wrong officials. With your address, you can identify all of your elected representatives: two U.S. senators (the same for every Marylander), one U.S. House member, one state senator, and up to three state delegates, plus your county officials.
Why ZIP Code Alone Isn’t Enough
ZIP codes exist to sort mail, not to define political districts. A single ZIP code can straddle two or more congressional districts, legislative districts, or county council districts. Political boundaries are redrawn after each census based on population, while postal routes are designed around delivery efficiency.1National Conference of State Legislatures. Redistricting and Use of Census Data The overlap between the two systems is essentially random. Search by ZIP alone and you risk contacting an official who cannot help you because you don’t live in their district. This matters most in suburban areas near district borders, where neighbors on the same block can have different representatives.
The Three Lookup Tools You Need
Between these three official tools, you can identify every federal and state official who represents you in about two minutes.
Maryland General Assembly: State Senator and Delegates
The Maryland General Assembly hosts a “Find My Representatives” tool that maps your street address to your legislative district and displays your state officials.2Maryland General Assembly.

House.gov: Your U.S. Representative

Senate.gov: Your U.S. Senators
No address lookup is needed for the Senate. Both senators represent the entire state, and Maryland’s senate page lists them with links to their offices.4United States Senate. States in the Senate – Maryland Maryland’s current senators are Angela Alsobrooks and Chris Van Hollen.
Who Represents You at Each Level
U.S. Senate
Every state elects two U.S. senators, and they represent the whole state rather than a district. Your address doesn’t change who they are.
U.S. House
Maryland has eight congressional districts, each electing one member to the U.S. House.5Maryland State Archives. Maryland General Election 2024 – U.S. Representatives Your address decides which of the eight is yours.
State Senate and House of Delegates
The Maryland General Assembly has 47 legislative districts. Each district elects one state senator. Each district also elects three delegates, but the setup varies: some districts elect all three at-large, while others are split into sub-districts labeled A, B, and C that each elect one or two delegates.6Maryland State Archives. Maryland House of Delegates – By District Depending on where you live, you may vote for three delegates or just one. The General Assembly has 47 senators and 141 delegates in total.7Maryland General Assembly. About the General Assembly
Local and County Officials
Maryland’s 23 counties and the City of Baltimore each have their own elected officials, including county executives or commissioners and county council members.8Maryland State Archives. Maryland Local Government – Counties and Municipalities These officials handle zoning, local police funding, property taxes, and public schools. County council districts are separate from both congressional and legislative boundaries, so your address falls within yet another set of lines.
To find your county representatives, visit your county government’s website; most Maryland counties publish a council district lookup or list members by district. The Maryland State Board of Elections also maintains district information tied to your address.9Maryland State Board of Elections. Maryland Districts
Keep Your Registration Address Current
Your representatives are tied to the address on your voter registration. If you’ve moved within Maryland, update your registration with the new address so your assignments stay accurate. Maryland requires you to register at least 21 days before an election if you register online or by mail, though same-day registration is available in person during the early voting period.10Vote.gov.
