Maryland filed nearly 42,000 Do Not Call complaints with the FTC. In Baltimore area codes 410 and 443, callers claiming a grandchild is in jail and needs bail money immediately are among the most reported threats. The DC suburb codes 301 and 240 are frequently used by callers claiming your Social Security number has been suspended. When emotions run high from a supposed family emergency or federal threat, pause and search the number in our Maryland reverse phone lookup. It could prevent a devastating financial loss.
Western and central Maryland, including the D.C. suburbs, are covered by 301, the overlay 240, and newer 227, serving Germantown, Silver Spring, Waldorf, Frederick, Rockville, Bethesda, Gaithersburg, and Bowie. The 301 code is frequently used for grandparent bail money shakedowns and property purchase text blasts, while 240 has been linked to fake NIH grant scams demanding registration fees and phantom debt collection threats. Callers from 227 have been running deceptive political surveys to build personal profiles for resale to telemarketers. Victim reports for all three codes are available in our 301 phone number lookup, 240 reverse phone lookup, and 227 area code lookup.
The Baltimore region is served by three overlay codes: 410, 443, and 667, covering Baltimore, Columbia, Glen Burnie, Ellicott City, Dundalk, and Towson. Scammers using 410 have spoofed urgent care caller ID to run utility switching schemes and send fake security software invoices, while 443 callers have posed as aggressive real estate recruiters and pressured seniors with unwanted in-home medical visit pitches. The 667 code has been associated with phishing texts impersonating the state unemployment system and hostile debt collectors who refuse to identify themselves. Reports for all three Baltimore-area codes are available in our 410 phone number lookup, 443 reverse phone lookup, and 667 area code lookup.
In 2024, Maryland residents filed 41,831 unwanted call complaints with the FTC, of which 22,144 were robocalls and 16,196 involved live callers. The most reported complaint topics were reducing debt (3,711), imposters (2,983), medical and prescriptions (2,232).

Yes. Maryland does not restrict the personal use of reverse phone lookup services, and its privacy law - which took effect October 1, 2025 - is considered one of the strongest in the country. The Fair Credit Reporting Act (FCRA) prohibits using lookup results for employment, tenant, or credit decisions in every state. Maryland's MODPA goes well beyond the federal baseline.
The Maryland Online Data Privacy Act (MODPA, Md. Code, Com. Law § 14-4601 et seq., enacted May 9, 2024) took effect October 1, 2025. Note that it does not apply retroactively to personal data processed before April 1, 2026. What makes MODPA stand out is its data minimization requirement: businesses may not collect or process personal data beyond what is "reasonably necessary and proportionate" to deliver the requested service (MODPA § 14-4604(a)). This is a stricter standard than most states, which only require an opt-out option after collection has already occurred. Maryland also covers nonprofits broadly - only a narrow exception for organizations processing data solely to assist law enforcement or first responders is carved out (§ 14-4602(b)).
Residents have a 45-day response window for access, correction, deletion, and portability requests. There is no small-business exemption.
Under the Maryland Online Data Privacy Act (MODPA), effective Oct. 1, 2025, you can request deletion of your phone number and personal details. Visit each reverse lookup site and submit a removal request through their opt-out settings.
Getting a business name from a phone lookup is helpful, but verification is key. With over 142,481 business establishments in Maryland according to Census data, confirming the company through the Maryland Business Express Search is the safest approach.
Maryland has 7.3 million mobile subscriptions, 1.6 million VoIP numbers, and 412,000 landlines. The VoIP share is higher than the national average, likely tied to the large number of government contractors and tech workers in the state.
