Look Up Maryland Phone Numbers

How to Look Up Maryland Phone Numbers

Start with the layer that owns the subject. Maryland state agencies handle driver licensing, unemployment, taxes, professional licenses, and state highways. Counties handle property tax bills, permits, local police, health clinics, and social services. Cities and towns handle the smallest local matters, and school systems, libraries, and utilities each keep their own directories. Guessing the layer wrong is the single biggest time waster in a Maryland phone number search.

Directories fail sometimes. A page is down, a name is spelled differently, or the person you want is not listed at all. There is a fallback chain for that, and it works in every Maryland county.

• Dial 311 where the county runs it, or the county main number where it does not
• Call the agency switchboard and ask to be routed by subject rather than by name
• Dial 211 for anything involving benefits, housing, food, or crisis services
• Look the office up in the Maryland Manual when you cannot name it
• File a Public Information Act request when a number is genuinely not published

Relay users have a route too. Dial 711 for Maryland Relay, which most state and county pages list alongside their voice numbers.

Maryland State Employee Phone Directory

The Department of Information Technology runs the Maryland Statewide Directory, which is the only search that reaches individual state workers by name. Enter a last name, add a first name or pick an agency, and submit. The agency dropdown is long and covers cabinet departments, the Comptroller, the Attorney General, the Judiciary, the State Police, the Public Service Commission, the MDOT administrations, and the University System campuses. A first name alone rarely works. A last name usually does.

What comes back is a work record, not a personal one. Directory results are limited to the information the state publishes for business contact.

Agency main numbers are the other half of this. The Motor Vehicle Administration takes calls at 410-768-7000. Unemployment claims go to 667-207-6520 on weekdays from 8 a.m. to 4 p.m. Emergency management questions, which are not 911 calls, go to 410-517-3600. Election questions go to 410-269-2840 or 800-222-8683.

The Motor Vehicle Administration site is a good example of how a Maryland agency routes calls before you ever reach a person.

Most of what people call the MVA about can be done online first, which is why the contact center number sits behind the service menus.

The Department of Labor contact page takes the opposite approach and lists divisions separately.

Unemployment, licensing, and workplace safety each have their own contacts there, along with Spanish-language resources and the relay listing.

County and Local Numbers in Maryland

Maryland has 23 counties plus Baltimore City, which governs itself and is not part of Baltimore County. Each of the 24 publishes its own contacts, and the depth varies. Montgomery County runs a full employee phone book searchable by first name, last name, and department, with everything from the Board of Elections to Fire and Rescue in the dropdown. It needs at least one letter in a name field before it will run. Frederick County, Prince George's County, and St. Mary's County publish staff directories of their own, and Carroll County routes most calls through 410-386-2085.

Five jurisdictions answer service requests on 311. Baltimore City takes them from 6 a.m. to 10 p.m. daily, or on 443-263-2220 from outside the city. Montgomery County uses MC311 or 240-777-0311. Prince George's County uses PGC311 or 301-883-4748. Anne Arundel County lists 410-222-7000 and Baltimore County lists 410-887-0311.

State services also have local branches, and the branch number is usually better than the statewide line. The MVA location lookup is the clearest example.

Pick a branch and you get its address, its hours, and the services it actually offers, which differ from one office to the next.

State Police cover the counties without a full local force. Headquarters answers at 410-486-3101, and 23 barracks split the rest of the state by county.

Maryland Public Safety Phone Numbers

Short numbers carry most of the load in Maryland. Anything urgent goes to 911. A mental health or substance use crisis goes to 988, which takes calls, texts, and chats and offers a veterans path, a Spanish path, and an ASL option. Everything else has its own line, and using the right one keeps 911 clear for real emergencies.

Non-emergency dispatch is a county matter. Prince George's County takes those calls at 301-352-1200. Anne Arundel County lists police at 410-222-8610, the sheriff at 410-222-1570, fire at 410-222-8300, and animal services at 410-222-8900. Other counties publish their own, usually on the police department's contact page.

• Child or adult abuse - 1-800-917-7383, or 911 for immediate danger
• Missing persons and alerts - 1-800-637-5437 after filing with local police
• Domestic violence - 1-800-799-7233 nationally, with local programs listed by 211
• Sexual assault - 800-656-4673, with chat and text options
• Human trafficking - 1-888-373-7888, or text HELP to 233733
• State Fire Marshal - 410-653-8980
• Sex offender registry - 410-585-3600

Maryland School and University Directories

Every one of Maryland's 24 school systems publishes contacts, and the state education department ties them together. MSDE answers at 410-767-0100 and lists each system with its superintendent, mailing address, and main number. Baltimore City is 410-396-8803, Baltimore County is 443-809-4281, Montgomery County is 240-740-3020, and Prince George's County is 301-952-6008.

Montgomery County Public Schools runs the most capable staff search in the state, and the advanced form is worth knowing because it accepts a phone number as a search term. That makes it one of the few directories anywhere that works in reverse.

The rest of the education layer follows the same pattern. Baltimore City Public Schools answers at 443-984-2000 and keeps a staff search that updates itself. Baltimore County Public Schools answers at 443-809-4554 and publishes office-level numbers, including transportation at 443-809-4321. AskMCPS handles general Montgomery County questions at 240-740-3000, with Spanish at 240-740-2845.

The University System directory needs at least three characters in a name field and lets you filter by campus. University of Maryland campus information answers at 301-405-1000.

Maryland Utility Phone Numbers

Maryland utilities publish two sets of numbers, and calling the wrong one costs you an hour. Outage and leak lines run around the clock. Billing lines keep office hours. Gas is the one to be careful with: Washington Gas tells customers to call 911 first if they smell gas, then report the leak.

Miss Utility splits the state by shore. Western Shore requests go to 800-257-7777 and Eastern Shore requests go to 800-441-8355, with a help desk at 410-712-0056 in Hanover. Routine tickets are taken on business days from 7 a.m. to 5 p.m. and stay valid for 12 business days. Emergency locates are taken at any hour.

Water and sewer are mostly local in Maryland. Frederick runs one line at 301-600-1440 for water quality, street leaks, and sewer backups, with billing on a separate number. Howard County bills water and sewer at 410-313-2058. Transit questions go to MDOT MTA at 410-539-5000 or 1-866-743-3682, with mobility services at 410-764-8181.

Health and Social Services Numbers in Maryland

211 Maryland is the widest door into social services here, with more than 7,500 listings behind it. Calls are free and confidential, and the service covers food, housing, utility assistance, child care, legal aid, employment, veterans benefits, and aging services. If the three-digit code fails, United Way of Central Maryland lists 410-685-0525 for greater Baltimore and 800-492-0618 elsewhere in the state.

Programs themselves run through two Maryland departments. The Department of Human Services answers at 1-800-332-6347 from 25 South Charles Street in Baltimore and keeps a local office in every county. The Department of Health answers at 410-767-6500 from 201 West Preston Street. WIC has its own customer service line at 800-242-4942, and the Department of Aging answers at 410-767-1100 or 800-243-3425.

Hospitals list their own switchboards. The University of Maryland Medical Center is 410-328-8667, with Shock Trauma patient information at 410-328-3697. UM Capital Region Health answers at 240-677-1000. Veterans reach VA Health Connect at 855-679-0250, with the Baltimore VA at 410-605-7000 and mental health appointments at 410-605-7417.

Crisis response is regional. Montgomery County runs a 24-hour crisis center at 240-777-4000. Grassroots covers the Howard County area with mobile crisis at 410-531-6677. Mid-Shore services on the Eastern Shore route through 988 and local lines such as 410-820-5600.

Maryland Records, Court, and Licensing Numbers

Record requests scatter across several offices in Maryland. Birth, death, and marriage certificates come from the Division of Vital Records at the health department, which also verifies divorces back to 1992. Marriage licenses themselves are issued by circuit court clerks, so the county matters. Property assessments belong to SDAT at 410-767-1184, or 1-888-246-5941 from outside the Baltimore metro area. Business filings run through SDAT at 410-767-1330 and through Maryland Business Express.

The SDAT contact page separates assessment questions from business services, which are handled by different units.

Real Property Search is free to use, though it cannot be searched by owner name, which sends a lot of people to the phone instead.

Maryland court numbers follow the courthouse, not the state. Circuit clerks answer case and record questions county by county: Baltimore City at 410-333-3733, Anne Arundel at 410-222-1397, Montgomery at 240-777-9400, Prince George's at 301-952-3318, Howard at 410-313-2111, Frederick at 301-600-1976, and Allegany at 301-777-5923. The Office of the Public Defender answers at 1-877-430-5187, Maryland Legal Aid at 410-951-7750, and the court help center at 410-260-1392.

Licensing has its own set. Notary questions go to the Secretary of State at 410-974-5520. Business license questions go to the State License Bureau at 410-260-6240 or to the local clerk of court. Voter registration questions go to the State Board of Elections.

Checking an Unknown Maryland Number Officially

No government tool will hand you a stranger's name. What official channels do well is confirm whether a number belongs to the office a caller claims, and give you somewhere to report the call. That is usually the real question anyway, since most unknown Maryland calls are either a legitimate agency or someone pretending to be one.

1. Write down the number, the date and time, what the caller claimed, and any payment demand or callback number.
2. Check the area code against NANPA to confirm it is a real code and see where it was assigned.
3. If the caller claimed to be a state or county office, look that office up yourself in the Statewide Directory, the Maryland Manual, or the county site.
4. Call the office back on the number you found, never the number the caller gave you.
5. Report the call to the FCC and the FTC, and to the Maryland Attorney General if money changed hands.

Two other official routes are worth knowing. The Public Service Commission handles landline telephone service complaints at 410-767-8028, but not wireless, cable, or internet. The FCC's Reassigned Numbers Database exists for businesses checking whether a number was disconnected, not for consumer lookups.

Complaints go through the FCC Consumer Complaint Center, which sorts phone issues into categories.

For a robocall, pick unwanted calls and texts, then the general sub-category. Calls that spoofed your own number have a separate option.

Third-Party Lookup Tools for Maryland Numbers

The tools listed here are commercial services, not Maryland or federal government sources. They can be useful for spam reputation and sometimes for a name, but none of them is authoritative. Results go stale because numbers move between carriers, and the free tier of most of them shows less than the marketing suggests.

Whitepages reverse phone is the oldest of the group and the one most people try first.

Basic results are free and the detailed report is paid, which is the standard model across this category.

NumLookup takes a plain 10-digit number with the country code already set to +1.

It validates the format before it searches, so a mistyped Maryland number is caught right away.

Truecaller leans on user reports rather than carrier records.

That makes it decent at flagging a number many people have already reported, and weak on a number that just started calling.

Carrier tools are the quietest option and cost nothing extra. AT&T ActiveArmor, Verizon Call Filter, and T-Mobile Scam Shield all screen calls on the line itself, and the T-Mobile app includes a reverse number lookup.

Line Type Behind a Maryland Number

Line type explains a lot about a call. A landline cannot receive a text. A voice-over-internet number can be bought cheaply and thrown away, which is why scam operations like them. A mobile number can be carried between carriers as often as the owner wants. None of this is visible from the digits alone.

Portability is the reason cheap carrier lookups mislead people. The authoritative routing data sits with the Number Portability Administration Center, and access is limited to authorized users. Commercial services such as Twilio Lookup and free carrier-check sites give a clue, not an answer. If a prefix says Baltimore landline but the lookup says mobile, that Maryland number was almost certainly ported.

What the area code means for a number is covered in more depth on the Maryland phone area codes page.

Reporting Scam Calls in Maryland

Maryland sees the same scams as everywhere else, with a few local favorites. Jury duty impostors are the most persistent. The caller says you missed jury service, claims to be a marshal, a sheriff, or a court officer, and demands cash, gift cards, or crypto to avoid arrest. The U.S. District Court for Maryland warned about it in February 2026 and points people to the FBI Maryland Field Office at 410-265-8080, with genuine jury questions going to the clerk at 410-962-3090.

The federal court's alert spells out how the calls are scripted.

Real courts do not call about money, and the Maryland Judiciary said the same thing in March 2026 about fake court, parking, and toll texts.

Utility shutoff threats, government grant offers, and neighbor spoofing round out the list. The Maryland Attorney General noted in July 2026 that scammers now buy legitimate numbers and cycle through them, which makes blocking one number at a time close to useless.

Reporting takes a couple of minutes. The Do Not Call report form handles unwanted calls, and registration on the same site cuts down on legitimate telemarketing.

You can also register or report by phone at 1-888-382-1222, with a TTY line at 1-866-290-4236.

Money lost to a scam is a Maryland Attorney General matter. The Consumer Protection Division explains how to file.

Complaints go through a portal that requires registration, and the office does not accept anonymous reports. Their consumer line is 410-528-8662 or 1-888-743-0023.

Community Resource Numbers in Maryland

Plenty of the numbers Maryland residents actually need sit outside government offices. 211 Maryland carries a dedicated path for immigrants and new arrivals, with translation in more than 150 languages. Legal help for immigration cases runs through the People's Law Library directory, which lists intake lines such as Catholic Charities at 240-858-0958. The Pride Center of Maryland serves the LGBTQ community statewide from Baltimore at 844-774-3363.

Business and visitor numbers come up more often than Maryland residents expect, usually when verifying whether a call was real. The Maryland Chamber of Commerce answers at 410-269-0642 from Annapolis. Visit Maryland runs travel assistance at 877-333-4455. County tourism offices publish their own, including Howard County at 410-313-1900 and Dorchester County at 410-228-1000.

News tip lines are the last category worth saving. WBAL-TV takes tips at 410-338-6501, and WYPR answers at 410-235-1660.
