Homeland Security Contact Phone Number

The official Homeland Security contact phone number should be taken from the verified contact block on this page or confirmed on the Department of Homeland Security website. DHS does not operate one support desk for every issue, so identify the responsible agency before calling.

What is the official Homeland Security contact number?

Use the verified contact block shown above this article for the main Department of Homeland Security contact phone number. Because government contact details can change, confirm the number on the official DHS website before calling if there is any doubt.

1. Open {site} and find the Contact section.
2. Check that the page identifies the Department of Homeland Security as the agency.
3. Compare the listed DHS contact phone number with the verified contact block on this page.
4. If the two sources differ, use the number currently displayed by DHS rather than a number copied from a search result, forum, social post, or unsolicited message.

A search for a “homeland security customer service number” can be misleading. The main department may direct callers to a DHS component, which is a separate agency or office within the department that handles a particular type of matter.

Which DHS office should I contact?

The correct Department of Homeland Security contact number depends on the issue. Review any letter, email, receipt, application notice, travel document, or case page for the name of the agency already handling the matter.

• USCIS generally handles immigration applications, petitions, appointments, and case-related questions assigned to USCIS.
• CBP generally handles border inspections, ports of entry, customs matters, and some international travel issues.
• TSA generally handles airport security screening and related traveler programs.
• FEMA generally handles disaster assistance and emergency-management programs assigned to FEMA.
• The Secret Service handles matters within its own protective and investigative responsibilities.
• Other DHS offices handle areas such as cybersecurity, immigration enforcement, maritime safety, and departmental civil rights concerns.

These examples are only a routing guide. Open the official DHS site and use its component directory to confirm which office owns the issue. Contact Homeland Security by phone through the relevant component when the paperwork names one, rather than assuming the general DHS contact number can resolve every case.

What should I prepare before calling Homeland Security?

Prepare enough non-sensitive information to explain the issue and help the agent identify the correct office. Do not send passwords, verification codes, or full financial details in an ordinary message.

• The name of the DHS agency or component shown on the notice.
• A case, receipt, inquiry, or reference number, if one was officially assigned.
• The type of document, application, traveler program, inspection, or incident involved.
• The date and general location connected with the issue, when relevant.
• A short description of what happened and the specific help you need.
• Paper and a safe place to record the office name and any official reference provided during the call.

Keep the explanation brief: identify the agency, describe the issue, and state the requested next step. Provide sensitive identifying information only after you have verified that you reached the official office and the information is necessary for that matter.

How can I contact Homeland Security without calling?

DHS and its components may offer official online forms, office directories, postal channels, and accessibility services. The available method depends on the agency and the type of request.

1. Open {site} and select the Contact section or component directory.
2. Choose the agency responsible for the matter.
3. Look for an official contact form, office locator, mailing instructions, or accessibility option.
4. Read the form instructions before entering personal information, and submit only what the official form requires.
5. Save a confirmation or reference number without storing it on a shared device.

If calling is unavailable, use the official directory to locate an appropriate communication method. Do not guess an email address or mailing destination, because different programs may require correspondence to go to different offices.

How do I avoid Homeland Security contact scams?

A caller, text sender, or email sender claiming to represent DHS is not automatically genuine. Impersonators may copy agency names, alter caller ID, create urgency, or direct people to an unofficial homeland security contact number.

• Do not trust a number only because it appears in caller ID or at the top of a search result.
• Be suspicious of threats demanding immediate payment or secrecy.
• Do not share passwords, one-time verification codes, or complete payment account details.
• Do not follow instructions to use gift cards, cryptocurrency, wire transfers, or other unusual payment methods.
• End an unexpected call and independently verify the DHS contact number through the official department or component page.
• Use the official reporting channel listed by the relevant agency if you believe someone impersonated a government employee.

Requests for urgent payment, pressure not to speak with anyone else, and refusal to identify the responsible DHS component are strong warning signs. Verification should be independent: do not call back using only the number supplied by the person who contacted you.

Frequently asked questions about contacting Homeland Security

Is there one department of homeland security contact number for every problem?

No. DHS includes multiple components, and immigration, airport screening, border, disaster, cybersecurity, maritime, enforcement, and protective matters may go to different offices.

How do I find a specific DHS component?

Check the agency name on your official paperwork, then use the DHS component directory. If no agency is named, use the general contact channel to ask where the matter belongs without assuming that office can resolve it.

Can I use a DHS contact phone number from outside the United States?

Confirm the appropriate international contact instructions on the official page for the responsible component. Calling availability and dialing requirements can vary, so do not rely on an unverified directory.

What should I do in an urgent situation?

Call emergency services for an immediate threat to life or safety. For a time-sensitive agency matter that is not an emergency, use the urgent-contact instructions published by the component responsible for the case.

What if the main number cannot answer my question?

Ask which DHS component owns the issue and record its official name. Then verify that component’s contact details through the official DHS directory before making another call.
