Maryland law restricts certain practices that conceal or misrepresent the identity of telephone solicitors. Businesses making covered solicitations generally must transmit accurate caller identification information and cannot deliberately display misleading numbers to hide their identity.
These restrictions help consumers recognize suspicious communications and understand their legal protections.
Caller ID information often influences whether a person answers an incoming call.
When that information is manipulated, consumers may believe a call comes from a local business, familiar organization, or trusted contact.
Maryland's Stop the Spam Calls Act addresses deceptive caller identification practices.
What caller ID spoofing means
Caller ID spoofing occurs when technology changes the number or identity information displayed to a telephone recipient.
Not every substitution is unlawful.
Some businesses use authorized customer service numbers or display the identity of the seller they represent.
Maryland law recognizes certain legitimate substitutions.
The legal concern arises when callers deliberately display another originating number to conceal their true identity during covered telephone solicitations.
The caller's purpose and conduct matter when determining whether a violation occurred.
Maryland's caller identification requirements
Maryland Commercial Law § 14-4502 generally requires covered telephone solicitors to transmit their originating telephone number.
The caller's name must also be transmitted when available through the carrier.
The statute prohibits intentionally preventing the transmission of caller identification information when the calling equipment supports it.
It also prohibits deliberately displaying a different number to hide the caller's true identity.
These provisions address several methods used to make telephone solicitations harder to trace.
A displayed local area code does not necessarily mean the caller is physically located nearby.
Consumers should avoid treating caller ID information as proof of identity.
Local spotlight: Maryland area codes and consumer protection
Maryland law establishes a rebuttable presumption involving telephone solicitations made to Maryland area codes.
Under § 14-4503, such calls are presumed to reach a Maryland resident or someone reasonably presumed to reside or conduct business in the state.
This provision may be relevant when a caller operates outside Maryland.
However, the presumption can be challenged with contrary evidence.
It does not automatically establish that every call to a Maryland area code violates state law.
The caller's conduct must still satisfy the requirements of an applicable prohibition.
Voice alteration and deceptive calls
Maryland also restricts certain intentional alterations of a caller's voice.
The statute addresses voice changes designed to conceal identity for fraudulent, confusing, or otherwise prohibited purposes.
For example, deliberately disguising a voice to obtain personal information unlawfully may raise concerns under the statute.
The restriction is tied to the prohibited purpose.
It does not mean that every use of synthetic or modified audio is automatically illegal.
Consumers receiving suspicious calls should avoid sharing sensitive information until the caller's identity can be independently verified.
Common questions around Maryland caller ID spoofing
Is every changed caller ID number illegal?
No. Maryland permits certain legitimate substitutions. Deliberate concealment of the caller's true identity during covered solicitations is restricted.
Can a caller display a local Maryland number from another state?
A displayed area code does not prove the caller's physical location. Legality depends on the circumstances and applicable rules.
Does Maryland regulate deceptive voice alteration?
Yes. Certain intentional voice alterations used for prohibited purposes are restricted.
How should suspicious calls be documented?
Consumers can preserve call records, screenshots, voicemails, and any information identifying the caller.
