To request phone records, log in to your carrier’s account portal, app, or call customer service to pull your own call and text logs after passing identity verification; to get someone else’s records, you need either their consent or a subpoena issued in an active legal case. Federal law treats those two paths very differently, and it treats call metadata (numbers, times, durations) very differently from message content.
Requesting Your Own Records From the Carrier
Every major carrier lets account holders view call and text logs through the online account portal or mobile app. Sign in, open the usage or billing section, and pull detailed records for your line. You can also call customer service or visit a retail store, but the carrier will verify who you are before releasing anything.
That verification is required, not optional. FCC rules covering Customer Proprietary Network Information (CPNI) require carriers to authenticate you before disclosing call detail information. Phone and online requests need a password you set up in advance; in-store requests need a valid photo ID that matches the account.1eCFR. 47 CFR Part 64 Subpart U – Privacy of Customer Information This is why a carrier will refuse to release your own records over the phone even if you can recite your Social Security number and billing address.
On a family or multi-line plan, the primary account holder has administrative access to call and text logs for every line on the account.2T-Mobile Support. Set Online Permissions Individual line users on that plan may not see other lines’ data unless the primary holder grants those permissions.
What the Records Show and How Far Back They Go
What you get from a carrier is metadata about your communications, not the communications themselves. FCC regulations define call detail information as the number called or calling, the date and time, the duration, and in some cases the location.1eCFR. 47 CFR Part 64 Subpart U – Privacy of Customer Information Text logs similarly show timestamps and phone numbers. Standard records requests will not give you the actual content of text messages or voicemails. Carriers generally delete message content within days, and the content that does exist gets stronger federal protection than metadata does.
Retention has a federal floor for toll (long-distance) calls: carriers offering toll telephone service must keep billing records for at least 18 months, including caller name, number called, date, time, and length.3eCFR. 47 CFR 42.6 – Telephone Toll Records In practice, major carriers voluntarily hold call detail records longer, and periods vary by carrier. If a legal matter is coming, request records sooner rather than later. Records available six months ago may not be available next year.
Getting Someone Else’s Records With Their Consent
The easiest lawful path to another person’s records is their consent. The Stored Communications Act specifically allows a carrier to disclose non-content customer records when the customer gives lawful consent.4Office of the Law Revision Counsel. 18 USC 2702 – Voluntary Disclosure of Customer Communications or Records Consent can be informal (the account holder pulls up their portal and shows you) or formal (a signed written authorization presented to the carrier).
Written authorization is the right approach when you need the carrier to release records directly to you, such as helping with a legal matter or managing affairs for an elderly relative. Call the carrier first: many have their own authorization forms, and some will accept a power of attorney if the account holder is incapacitated.
Getting Records Through a Subpoena
When the other person won’t consent, the standard route is formal discovery in an active legal case: divorce, personal injury, employment, harassment, and similar matters. The tool is a subpoena duces tecum, a court-backed order directing the carrier to produce specific documents.
Under the Federal Rules of Civil Procedure, an attorney authorized to practice before the issuing court can draft and sign the subpoena without a judge’s signature. It must identify the court, the case name and number, and command production of specific documents at a set time and place.5Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena For phone records, that means specifying the phone number, the carrier, and the exact date range. Overly broad requests get quashed. “All records for the past ten years” with no explanation of relevance will not survive a challenge.
Before serving the carrier, the requesting party must serve a copy of the subpoena on every other party in the case.5Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena The notice requirement is not a technicality; it gives the person whose records are being sought a chance to fight before anything is turned over.
The subpoena then goes to the carrier’s legal compliance department or registered agent. Each major carrier has a dedicated team for these requests. Expect a processing fee and expect weeks, not days, for the response.
One practical limit to plan around: a civil subpoena to a carrier will produce call detail records (timestamps, numbers, durations). It will not produce the text or content of messages. Courts have consistently held that a civil subpoena from a private party is not one of the Stored Communications Act’s listed exceptions permitting disclosure of message content.4Office of the Law Revision Counsel. 18 USC 2702 – Voluntary Disclosure of Customer Communications or Records If you need actual message content, direct discovery at the other party, who may still have the messages on their device.
If Someone Subpoenas Your Records
You have the right to fight a subpoena for your records. The mechanism is a motion to quash, filed in the court where compliance is required. Under Rule 45, a court must quash or modify a subpoena that fails to allow reasonable time to comply, demands privileged or protected information, or subjects the recipient to undue burden.5Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena
“Undue burden” is the most commonly argued ground. If the records sought have nothing to do with the case, or the date range is unreasonably broad, the court is likely to narrow or kill the subpoena. Speed matters. If you get notice and do nothing, the carrier will comply and produce the records. Putting that genie back in the bottle is much harder after the fact.
Using the Records as Evidence
Getting records produced is one thing. Getting them admitted at trial is another. Carrier records come in as business records under the hearsay exception for records of a regularly conducted activity. To qualify, the records must have been made at or near the time of the events they document, kept in the course of a regularly conducted business activity, and created as a regular practice of that business.6United States Courts. Federal Rules of Evidence Carrier call logs easily meet all three.
Authentication is the practical step. Rather than fly a records custodian in to testify, most attorneys use a certification. A qualified person at the carrier signs a written statement that the records are authentic and were kept in the ordinary course of business, which makes them self-authenticating under the Federal Rules of Evidence.7Legal Information Institute. Federal Rules of Evidence Rule 902 – Evidence That Is Self-Authenticating When you subpoena records, ask for the custodian certification at the same time.
The Illegal Shortcuts and Their Penalties
Federal law treats unauthorized access to phone records as a serious crime. The Telephone Records and Privacy Protection Act makes it a federal offense to fraudulently obtain confidential phone records, sell or transfer records you know were obtained illegally, or purchase records knowing they were stolen. The base penalty runs up to 10 years in federal prison.8Office of the Law Revision Counsel. 18 USC 1039 – Fraud and Related Activity in Connection With Obtaining Confidential Phone Records Information of a Covered Entity
For aggravated cases involving more than $100,000 in value or more than 50 affected customers within a 12-month period, an additional five years of potential imprisonment stacks on top of the base sentence.8Office of the Law Revision Counsel. 18 USC 1039 – Fraud and Related Activity in Connection With Obtaining Confidential Phone Records Information of a Covered Entity The statute was enacted specifically to address “pretexting”: calling a carrier while impersonating the customer, or using other deceptive tactics to trick the company into releasing records.
Hiring an investigator who pretexts, buying records from an online service, or social-engineering a customer support line are all federal crimes. If someone won’t hand over records voluntarily, the courthouse is the only lawful route.
Emergency and Law Enforcement Disclosures
Two situations sit outside the consent-or-subpoena framework, and they involve government access rather than private requests. The Stored Communications Act allows a carrier to voluntarily disclose contents and customer records to a government entity when it believes in good faith that an emergency involving a risk of death or serious physical injury requires immediate disclosure.4Office of the Law Revision Counsel. 18 USC 2702 – Voluntary Disclosure of Customer Communications or Records Active kidnappings, bomb threats, and suicide interventions are the kind of situations this exception covers.
In Carpenter v. United States (2018), the Supreme Court held that the government generally needs a warrant supported by probable cause to obtain historical cell-site location information tracking a phone’s movements over time. The Court described that location data as providing “an intimate window into a person’s life” and found the lower SCA standard insufficient.9Supreme Court of the United States. Carpenter v. United States The ruling was narrow, applying specifically to historical location records, and left open exceptions for emergencies and shorter time periods.
