TLDR
The phone number 0000000000 has accumulated 1,345 FTC complaints and 423 FCC complaints for a combined total of 1,768 reports, making it one of the most reported caller IDs in America. It is not a real phone number. It is a spoofed caller ID that appears when robocall systems fail to inject a convincing fake number, or when the spoofing is deliberately set to all zeros. ScamVerify™ cross-database analysis reveals that 61% of calls from 0000000000 are robocalls, and the complaints span multiple scam categories. A related spoofed ID, 1111111111, has 729 FTC and 73 FCC complaints (802 total). These numbers are the ghost signatures of mass robocall operations.
What 0000000000 Actually Is
When your phone displays "0000000000" as the incoming caller ID, you are not receiving a call from a phone number consisting of ten zeros. That number does not exist as an assigned phone number. What you are seeing is one of two things:
1. A spoofing failure. Robocall systems use caller ID spoofing to display fake local numbers, making the calls appear to come from nearby area codes. When the spoofing system fails to inject a number, some VoIP systems default to 0000000000 as a placeholder.
2. Deliberate zero spoofing. Some robocall operations intentionally set the caller ID to 0000000000 because it still triggers the phone to ring. The scammers know the number looks suspicious, but they are playing a volume game. If they dial millions of numbers, enough people will still answer.
In both cases, the call originates from a VoIP system that is likely operating from outside the United States or using anonymized infrastructure.
The Complaint Data
FTC Complaints: 1,345
| Subject Category | Complaints | Percentage |
|---|---|---|
| Other | 618 | 46.0% |
| Dropped call/no message | 303 | 22.5% |
| Impersonation | 114 | 8.5% |
| Medical/prescriptions | 86 | 6.4% |
| Debt reduction | 79 | 5.9% |
| Warranties/protection | 53 | 3.9% |
| Other categories combined | 92 | 6.8% |
The "Other" category being the largest is itself informative. When callers cannot categorize the scam because the call was garbled, incomprehensible, or the victim hung up before hearing the pitch, it lands in "Other." This is consistent with automated robocall systems where many calls fail to deliver their message properly.
The 303 dropped calls (22.5%) indicate that many of these are predictive dialer operations. Predictive dialers call more numbers than available agents can handle, and some calls get dropped when no agent is available. The system called, connected, and immediately disconnected.
FCC Complaints: 423
The FCC complaint data overlaps with but does not duplicate FTC data. The 423 FCC complaints against 0000000000 bring the combined total to 1,768 reports across both agencies.
Robocall Rate: 61%
Of the FTC complaints where call type was identified, 61% were classified as robocalls (pre-recorded message with no live person). This is lower than the 85-91% robocall rate seen in organized scam rings, suggesting that 0000000000 is used by multiple different operations, some automated and some with live callers.
Activity Timeline
Reports against 0000000000 have been consistent since at least December 2022, with no seasonal pattern or decline:
| Period | Trend |
|---|---|
| Dec 2022 - Jun 2023 | Steady complaint flow |
| Jul 2023 - Dec 2023 | Slight increase |
| Jan 2024 - Jun 2024 | Consistent |
| Jul 2024 - Dec 2024 | Consistent |
| Jan 2025 - Dec 2025 | Slight increase |
| Jan 2026 - Mar 2026 | Ongoing |
The persistence is notable. Unlike specific scam ring numbers that eventually get blocked and replaced, 0000000000 continues generating complaints because it is not one operation. It is a default ID used by many different robocall systems across different scam categories.
The 1111111111 Pattern
A closely related spoofed caller ID, 1111111111, shows a similar pattern:
| Metric | 0000000000 | 1111111111 |
|---|---|---|
| FTC complaints | 1,345 | 729 |
| FCC complaints | 423 | 73 |
| Combined total | 1,768 | 802 |
| Top category | Other (618) | Other/impersonation |
| Robocall rate | 61% | Similar |
| Active since | Dec 2022 | Dec 2022 |
Both are obviously fake numbers. Both represent spoofing system defaults or intentional placeholder IDs. Both are used by multiple unrelated scam operations.
Other reported "impossible" caller IDs include:
- 0000000001 (minimal complaints, same pattern)
- 1234567890 (sequential digits, spoofing test/default)
- 9999999999 (all nines, another placeholder)
- Single-digit numbers (1, 0, etc.)
These are all signatures of VoIP systems that either failed to spoof a convincing number or were not configured to do so.
How Caller ID Spoofing Works
Understanding why 0000000000 appears on your phone requires understanding caller ID spoofing:
The Technical Process
- VoIP origination. The scam call originates from a VoIP (Voice over IP) system, not a traditional phone line.
- Caller ID injection. The VoIP system allows the caller to set any number as the outgoing caller ID. This is a feature of the SIP (Session Initiation Protocol) that VoIP runs on.
- Network propagation. The spoofed caller ID propagates through the phone network and appears on the recipient's phone.
- Display. Your phone shows the injected number as if it were the real originating number.
Why Spoofing Is Still Possible
The STIR/SHAKEN framework was designed to authenticate caller IDs and flag unverified ones. However:
- Implementation is incomplete across all carriers
- International calls often bypass STIR/SHAKEN
- Some VoIP providers do not fully participate
- 0000000000 calls may still display because the system recognizes them as unverified but does not block them
The 0000000000 Default
Many VoIP systems set the default caller ID to 0000000000 or blank when no specific spoofed number is configured. Scam operations that focus on volume over sophistication may not bother configuring caller ID spoofing for every campaign, resulting in the all-zeros default.
What This Tells Us About Robocall Infrastructure
The existence of 0000000000 as a persistent top complaint target reveals several things about the robocall ecosystem:
Scale over sophistication. The operations using 0000000000 are optimizing for call volume, not caller ID credibility. They know the number looks fake, but they dial enough people that a small percentage still answer.
Multiple operators. The diverse complaint categories (debt, medical, impersonation, warranties) indicate that 0000000000 is not one scam ring. It is a default ID used by many different operations with different pitches.
Infrastructure fragility. Calls displaying 0000000000 represent the lowest-effort tier of robocall operations. These are systems that did not invest in proper caller ID spoofing, did not configure their VoIP platform correctly, or experienced a spoofing malfunction.
Enforcement gap. Despite 1,768 combined complaints, there is no entity to enforce against. You cannot shut down a phone number that does not exist. Enforcement must target the VoIP providers and gateway carriers that allow these calls to enter the network.
How to Handle Calls from 0000000000
- Do not answer. A call from 0000000000 is guaranteed to be spoofed. No legitimate person or organization calls from this number.
- Block the number. While the same scammers may call from other numbers, blocking 0000000000 stops at least one channel.
- Do not call back. The number does not connect to anything.
- Report to the FTC at reportfraud.ftc.gov. Even though the number is fake, the complaint helps track the volume and categories of spoofed-ID robocalls.
- Enable carrier spam filtering. AT&T ActiveArmor, Verizon Call Filter, and T-Mobile Scam Shield can sometimes identify and flag calls from obviously spoofed numbers.

FAQ
Is 0000000000 a real phone number?
No. It is not assigned to any person, business, or organization. It is a spoofed caller ID that appears when a robocall system either fails to inject a convincing fake number or deliberately uses all zeros as a placeholder. You cannot call this number and reach anyone.
Why does my phone even ring for 0000000000?
Phone networks are designed to deliver calls regardless of the caller ID displayed. While STIR/SHAKEN authentication can flag unverified caller IDs, not all carriers block them outright. The call still arrives because the network processes the underlying connection separately from the displayed caller ID.
Can I sue the caller who used 0000000000?
Theoretically, TCPA (Telephone Consumer Protection Act) violations allow consumers to sue for robocalls. Practically, the caller cannot be identified from the spoofed number alone. The FTC and FCC investigate these patterns at the network level, tracing calls through carrier records to identify the originating VoIP provider, but individual consumers typically cannot access this information.
Does blocking 0000000000 actually help?
It prevents future calls that use that specific spoofed ID from ringing your phone. However, the same scam operations may call from other spoofed numbers (local numbers, 1111111111, or random digits). Blocking is one layer of defense, not a complete solution. Carrier spam filtering provides broader protection.
