Quick answer

For a U.S. spam-call complaint, start with the official route that matches what happened. Use the FTC's National Do Not Call Registry FAQs for registration questions and unwanted sales calls. Use the FCC's unwanted calls and texts complaint page for robocalls, spoofing, and other unwanted calls or texts. For a suspected scam or impersonation, file a report through the FTC's ReportFraud tool.

The templates below are written for an agency form's narrative box, a carrier's verified support channel, or a known company that keeps calling. They aren't meant to send you searching for an unverified government email address.

A complaint can help agencies spot calling patterns, but it won't automatically stop the calls, guarantee an investigation, create a private legal claim, or produce compensation. Stick to facts. Don't demand a particular fine or declare that a caller violated the TCPA unless you have a sound basis for that conclusion.

Which complaint route should you use?

The FCC says it doesn't resolve individual unwanted-call complaints. It uses complaint information to inform policy decisions and potential enforcement. The FTC likewise analyzes reports and trends to identify illegal callers and calling patterns.

Before you send a complaint

Make a short record before the details fade. Include:

• The number that received the call
• The caller ID number and name exactly as displayed
• The date, local time, and time zone
• Whether the call was live, prerecorded, or an interactive robocall
• The company or organization the caller named
• The product, service, or payment discussed
• Any callback number or website provided
• Whether you gave permission to be contacted
• Whether you had an existing customer relationship
• Whether you asked the company to stop calling
• Screenshots, voicemail files, call logs, and a brief transcript

Leave out your Social Security number, account password, online banking credentials, one-time code, and full payment-card number. If an official form asks for information that needs protection, enter it only in the form's secure fields, not in ordinary email.

Replace each bracketed item in the examples. Delete anything you can't verify, and use "suspected" when the facts don't establish who made the call or whether it was a scam.

10 spam call complaint email templates

The FTC and FCC generally collect complaints through online forms. For those agencies, treat the subject and body below as copy to adapt for the form rather than as an email address.

1. FTC Do Not Call complaint template

This version fits a suspected sales call to a number registered with the National Do Not Call Registry. If the call looked like an immediate scam, use the fraud-report template instead of waiting for the registry timeline.

Subject: Do Not Call complaint for [your number] on [date]

I am reporting a suspected unwanted sales call to my telephone number.

Number called: [your number]
Do Not Call registration date: [date]
Registration confirmation received: [yes or no]
Call date and local time: [date, time, and time zone]
Caller ID: [number and name shown]
Company or organization named: [name]
Product or service offered: [description]
Was the call prerecorded: [yes, no, or unknown]
Callback number provided: [number or none]

I [did or did not] give this company permission to call this number. I [did or did not] have an existing customer relationship with the company. If either fact is unknown, write "unknown" rather than guessing.

I have retained [call log, screenshot, voicemail, or transcript]. Please record this report with the other information about this caller.

The FTC says each number must be confirmed through the email link within 72 hours of registration, and up to three numbers can be registered at one time online. The registry is most relevant to sales calls after the applicable waiting period. Registration doesn't stop every kind of unwanted call.

2. FTC suspected scam or impersonation template

Use this when a caller claimed to represent a government agency, bank, delivery company, employer, utility, or another organization and asked for money or sensitive information.

Subject: Suspected phone scam or impersonation on [date]

I am reporting a suspected phone scam or impersonation attempt.

Number that received the call: [your number]
Date and local time: [date, time, and time zone]
Caller ID displayed: [number and name]
Organization the caller claimed to represent: [name]
What the caller said: [short factual summary]
What the caller requested: [money, gift card, account access, password, code, or other information]
Callback number or website provided: [details or none]

I [did or did not] provide money or information. If I provided anything, it was: [brief description]. I have retained [voicemail, screenshot, recording, payment record, or transcript].

Please record this report as a suspected scam.

Don't call the displayed number to verify the story. Caller ID can be falsified. If you need to check an account or transaction, use contact details you already trust rather than details supplied during the call.

3. FCC unwanted-call or robocall template

For a general FCC complaint, the FCC instructs consumers to select unwanted calls/texts as the phone issue and all other unwanted calls/messages as the sub-issue.

Subject: FCC unwanted-call complaint for [your number]

Phone issue: Unwanted calls/texts
Sub-issue: All other unwanted calls/messages

I am reporting an unwanted call received on [date] at [local time and time zone].

Number called: [your number]
Caller ID displayed: [number and name]
Caller or company identified: [name, or unknown]
Call type: [live call, prerecorded message, or robocall]
Description of the message: [brief transcript or summary]
Callback number or website mentioned: [details or none]
Number of similar calls: [number of calls and date range]
Do Not Call registration date, if applicable: [date or not registered]

The caller ID appeared [normal, local, blocked, or possibly spoofed]. I have retained [screenshots, call logs, voicemail, or recording]. Please add this information to the FCC's complaint data about unwanted calls.

Describe what you saw and heard rather than treating a local-looking number as proof of the caller's identity. The FCC may use the report for enforcement or policy work, but its complaint center doesn't resolve each individual call.

4. FCC own-number spoofing template

Choose this category when your own telephone number is being displayed as the caller ID. If the caller merely used a different local number, use the general unwanted-call template.

Subject: My telephone number is being spoofed

Phone issue: Unwanted calls/texts
Sub-issue: My own number is being spoofed

My telephone number is [your number]. I believe it is being used as caller ID by someone else.

Evidence:
- [Date and time a person returned a call saying they received a call from my number]
- [Date and time my phone displayed an outgoing call that I did not make]
- [Screenshot, carrier notice, or other evidence]
- [Number of known incidents]

I did not make the calls described above. My carrier is [carrier name], and the number is used on [mobile, landline, or internet phone service]. Please record this report under the own-number spoofing category and advise whether additional information is needed.

The FCC Consumer Complaint Center has a separate selection for a consumer's own number being spoofed, blocked, or labeled as a possible spam call.

5. Carrier spam-call support template

Send this through your carrier's official app, secure message center, or support page. An email address copied from a forum or social post isn't verified just because it appears in a template.

Subject: Spam-call report for [carrier] line ending in [last four digits]

I am requesting help with repeated unwanted calls to my [mobile or home] line.

Number receiving the calls: [your number]
First and most recent call: [dates]
Number of calls: [number]
Caller ID numbers shown: [list]
Company or message identified: [details]
Call type: [live, prerecorded, or robocall]

Please review these calls as spam and tell me which blocking or call-labeling options are available for my line. Please provide a support case number if one is created.

I have retained call logs and screenshots and can provide them through your secure support channel. I will not send passwords, full payment details, or verification codes by email.

Blocking and labeling tools can reduce unwanted calls, but they aren't a finding that the caller broke the law.

6. Carrier follow-up template

Use this after opening a carrier case or enabling a blocking feature and receiving more calls.

Subject: Follow-up on spam-call case [case number]

I am following up on case [case number], opened on [date], about unwanted calls to [your number or last four digits].

Since that report, I received:
- [date and time] from [caller ID number]
- [date and time] from [caller ID number]
- [date and time] from [caller ID number]

The messages were [brief description]. The calls [were or were not] labeled as spam, and I [did or did not] use the blocking feature called [feature name].

Please confirm whether the case is still open and tell me what additional call records you need. Please also identify the current blocking or call-labeling settings available for my account.

A carrier generally won't disclose another customer's information or identify the source of a spoofed call. Ask instead for the settings and reporting options available on your account.

7. Identified-business stop-marketing request

Send this only to a customer-service address or contact form published on the company's official website.

Subject: Written request to stop marketing calls to [your number]

To [company name]:

I am asking your company to stop placing marketing calls to [your number]. Please record this number on your internal do-not-contact list and confirm when the request has been processed.

Relevant calls include:
- [date and time] from [number]
- [date and time] from [number]
- [description of the offer or representative]

If a vendor or partner made these calls on your behalf, please identify the company responsible for the contact and tell me how this request will be shared with that vendor.

If you believe you have permission to call this number, please explain the source and date of that permission. Please do not request passwords, payment details, or security codes in your reply.

Save the sent message and the response. If you don't recognize the business or suspect impersonation, don't use its callback details; report the suspected scam instead.

8. Written stop request for a known caller

A written request can create a useful record, but it isn't a court order and won't reliably stop a scammer. Keep the wording neutral and factual.

Subject: Written request to stop marketing calls

To [company or caller name]:

I am requesting that you stop making nonessential marketing calls to [your number]. My call history includes:

- [date and time] from [number]
- [date and time] from [number]
- [date and time] from [number]

I have not requested these calls, or I previously asked that the calls stop on [date]. Please confirm receipt of this request and identify the correct contact method for any necessary account-related communication.

I am retaining this message and my call records. If marketing calls continue, I may submit the records to the appropriate carrier and government complaint channels.

Don't send this notice to a scammer, a spoofed number, or a caller asking for payment. Contacting the caller can confirm that your number is active.

9. Evidence addendum for repeated calls

Add this to an existing agency report, carrier case, or business complaint when more calls occur.

Subject: Additional call records for complaint [case number]

I am adding information to complaint or case [case number], submitted to [agency, carrier, or company] on [date].

Additional calls:
1. [date, local time, caller ID, and brief description]
2. [date, local time, caller ID, and brief description]
3. [date, local time, caller ID, and brief description]

The calls appear related because [same message, same callback number, same company name, or other factual connection]. I have retained [screenshots, call logs, voicemail files, or transcript].

Please attach this information to the existing report. I have removed passwords, payment information, and other unnecessary personal data.

A chronological log is more useful than a long description of how frustrating the calls are. If a form has a character limit, lead with the clearest and most recent examples.

10. Complaint follow-up template

This works for a carrier or known business. For the FCC, check the complaint center for its current process instead of assuming it will reply by email.

Subject: Follow-up on unwanted-call report submitted [date]

I submitted an unwanted-call report to [company, carrier, or agency] on [date]. The reference number is [number, if available].

The calls have [continued, stopped, or changed] since then. The latest examples are:

- [date and time] from [caller ID number]
- [date and time] from [caller ID number]

Please confirm receipt of this follow-up and tell me whether you need the original voicemail, screenshots, or a more detailed call log. Please send any response through [secure message center or verified contact method].

Practical subject lines

A good subject identifies the issue, date, or case number. It doesn't need a threat or a promise of fines.

1. FTC Do Not Call report for [your number]
2. FCC unwanted-call complaint from [date]
3. Suspected spoofed caller ID on [your number]
4. Suspected phone impersonation scam on [date]
5. Spam-call report for [carrier] line
6. Follow-up on spam-call case [case number]
7. Written request to stop marketing calls
8. Additional call records for complaint [case number]
9. Repeated robocalls to [your number]
10. Call-blocking help requested for [carrier] line

How to report spam calls step by step

1. Check your Do Not Call registration. The FTC lets you register up to three numbers at a time. Open each confirmation email and click its link within 72 hours. If you're reporting a sales call, record the registration date. FTC guidance says to report continued sales calls after the number has been on the registry for 31 days.
2. Report suspected fraud without waiting. A scammer doesn't become legitimate because your number isn't registered. Use the FTC's fraud-reporting route and include the caller's claims, requests, and contact details.
3. Preserve the details. Write down the local time, caller ID, number called, message, callback number, and company named. Save a voicemail, screenshot, or call log if available.
4. Choose the matching form. Use the FCC for unwanted calls, robocalls, texts, and spoofing. If your own number is being used as caller ID, choose the specific own-number spoofing sub-issue.
5. Turn to your carrier's official tools. The FTC's guidance on blocking unwanted calls covers mobile phones, home phones, call-blocking apps, and call-labeling tools. Verizon describes its robocall and Call Filter options. For AT&T account or fraud concerns, start with its official fraud and security guidance.
6. Save the confirmation. Keep the case number, submitted text, screenshots, and carrier response together.
7. Add later calls to the same record. Use the evidence-addendum template instead of deleting the original report.

What the Do Not Call Registry does not control

The registry covers many telemarketing sales calls, not every unwanted call. Political calls, charitable solicitations, surveys, informational calls, certain existing business relationships, and calls made with permission can be treated differently.

A scammer's prerecorded message or use of a spoofed number may raise separate issues. Registry status alone doesn't establish that every call was unlawful.

The FTC's Telemarketing Sales Rule guidance discusses telemarketing obligations and exceptions. The applicable rules can depend on the caller, purpose of the call, consent, technology used, and other facts.

What a complaint can and cannot do

A report gives regulators and carriers information that may help reveal a broader pattern. The FTC says illegal callers have paid more than $290 million in judgments, but past enforcement totals aren't a promise of a payment, fine, or investigation in your case.

The FCC expressly says that it doesn't resolve individual unwanted-call complaints. A submission can still contribute to enforcement and policy work, but it isn't the same as filing a court case. If you're considering an individual TCPA claim or another legal remedy, preserve your records and seek advice from a qualified professional in your state.

A carrier's block or "spam likely" label isn't a legal ruling either. It may reduce calls, while some unwanted calls still get through and legitimate calls can occasionally be mislabeled.

Common mistakes to avoid

• Sending a complaint to an unverified email address found in a forum or social post
• Treating a spoofed caller ID as proof that the displayed person or business made the call
• Calling back, pressing a number, or following an unsubscribe prompt in a suspicious robocall
• Claiming that a specific law was violated without recording the relevant facts
• Threatening a fixed fine amount or promising that regulators will contact the caller
• Including passwords, one-time codes, Social Security numbers, or full payment details
• Deleting the call log before recording the date, time, and displayed number
• Assuming Do Not Call registration will block political, charitable, survey, informational, or scam calls

Frequently asked questions

Is there one universal email address for spam-call complaints?

No. The FTC and FCC generally direct consumers to online complaint tools. Use these templates in the relevant form, through a carrier's verified support channel, or with an identifiable company's published contact method.

Should I report a robocall if my number isn't on the Do Not Call Registry?

Yes. You can report a suspected fraud, spoofed call, or other unwanted robocall even if the number isn't registered. The registry is most relevant to certain sales calls and isn't a requirement for reporting suspected fraud.

Will reporting a call make it stop?

Not necessarily. Blocking and call-labeling tools can reduce the calls that reach you, while agency reports help identify patterns. No complaint form guarantees immediate removal from a calling list.

Is every prerecorded call illegal?

No. The answer can depend on consent, the purpose of the call, the caller, exemptions, and the technology used. Describe what happened instead of relying only on the phrase "TCPA violation."

What should I do after a scam call?

Don't call back or share more information. Block the number, save the evidence, and report the suspected fraud to the FTC. If you disclosed payment or account information, contact your bank or affected provider through a verified channel.

Can I send a cease-and-desist email to a spam caller?

You can send a written stop request to a known, legitimate business through a verified contact channel. Don't send one to a suspected scammer or spoofed number. A cease-and-desist-style email creates a record, but it isn't a court order.

Where can I confirm current FCC complaint categories?

Use the FCC Consumer Inquiries and Complaints Center. Complaint screens and category names can change, so follow the options shown when you submit the report.
