Homeland Security Phone Number and Support

Find the verified Homeland Security phone number in the official contact block on this page or through the U.S. Department of Homeland Security website. Before calling, identify the DHS component agency or office responsible for your issue, because the department does not operate as one general customer-service center.

What is the official Homeland Security phone number?

The official Homeland Security phone number shown in the verified contact block is the safest starting point for a general department question. You can also open {site}, find the Contact section, and compare the listed number with the contact block before placing a Homeland Security call.

Confirm that the page identifies the U.S. Department of Homeland Security and uses an official federal government domain. An official domain is a web address reserved for a government organization. Do not rely on a number copied from an advertisement, social media post, forum, map listing, or unofficial directory.

There may not be one Homeland Security customer service number for every request. DHS contains multiple component agencies and offices, each with separate duties and contact channels. The main department contact may redirect you, but contacting the responsible component first can reduce unnecessary transfers.

Which Homeland Security department should I call?

Choose the DHS component that matches the subject of your question before calling. Use the official DHS component directory if the correct office is unclear.

• Contact the Transportation Security Administration for airport screening, traveler screening programs, or items connected with a security checkpoint.
• Contact U.S. Customs and Border Protection for customs, ports of entry, or border-processing questions.
• Contact U.S. Citizenship and Immigration Services for matters involving services or records administered by that agency. Use its official contact information rather than relying on general immigration advice from an unofficial source.
• Contact the Federal Emergency Management Agency for programs and records administered by FEMA.
• Contact the Cybersecurity and Infrastructure Security Agency for matters that fall within its cybersecurity and infrastructure responsibilities.
• Use the DHS headquarters or general contact office for department-wide questions, public information, or help identifying the appropriate component.

Other DHS components may handle specialized matters. Read the office description in the official directory instead of choosing an agency only because its name sounds related to your issue.

How do I call Homeland Security?

Prepare a short explanation of the issue and any relevant reference details before making a Homeland Security call. Do not share passwords, sign-in codes, or unrelated personal information.

1. Verify the number against the official contact block or the relevant agency’s official Contact page.
2. Write down the name of the DHS component, the topic of your request, and the outcome you need.
3. Gather relevant correspondence, reference numbers, dates, and the name shown on the record. Provide sensitive details only when the official office explains why they are needed.
4. Listen for the office name when the call connects. If the greeting names a different agency or business, end the call and verify the number again.
5. State the issue in one or two sentences. Ask whether the office handles that subject before giving a long explanation.
6. Record the office name, the date of the call, and any instructions provided. If transferred, confirm the name of the office receiving the call.

What happens next depends on the component and the type of request. A representative may answer a general question, direct you to another office, or explain the official channel required for the request. A call does not guarantee a response or resolution.

When is Homeland Security customer service open?

Operating hours vary by DHS agency, office, contact line, and service. Verify current hours on the official contact page for the specific component before calling; do not assume that the general department office and a component agency follow the same schedule.

Check whether the listed hours include a time zone and whether the office posts separate information about federal holidays or closures. If no hours appear, do not treat that as confirmation that the line is continuously staffed. Recorded information and live assistance may also have different availability.

The verified contact block on this page may show confirmed details, but the responsible agency’s official page is the best place to check for a recent schedule change.

What other official ways can I contact Homeland Security?

If telephone support is unavailable, open {site} and look for Contact, Components, Offices, or Accessibility. DHS and its component agencies may provide different channels for different subjects.

• Use an official online contact form when the form’s topic matches your request.
• Check the component or office directory for the agency responsible for the issue.
• Use a published mailing option only after confirming the office name and current mailing instructions on the official page.
• Review the relevant accessibility section for relay services, accommodations, or other communication options offered by that office.
• Follow instructions in an official letter when the letter identifies a specific reply channel, but independently verify unexpected contact before sending personal information.

Do not send sensitive records through a general form unless the official instructions specifically request them. Online forms, mail, and accessibility channels have different purposes, and none guarantees a response.

What should I do if I cannot reach the right Homeland Security office?

If a Homeland Security phone number does not connect you with the correct office, verify both the number and the agency assignment before trying again. Repeatedly calling the same general line may not help when a component agency owns the issue.

1. Compare the number with the official contact block and the component’s official Contact page.
2. Check the DHS component directory and read each office description carefully.
3. Try the appropriate agency’s official contact form or another published channel if telephone support is unavailable.
4. Document the date, office name, and result of each attempt so you can explain where you were directed.
5. Ask the verified general contact office to identify the responsible component if the directory does not settle the question.

Be cautious if a caller claims to represent Homeland Security and pressures you to act immediately, disclose a password or verification code, or use an unofficial contact method. End the interaction and independently locate the agency through the official DHS site. Do not return a call solely because a number appeared on caller ID, since displayed caller information can be misleading.
