Department of Homeland Security Phone Number

The correct Department of Homeland Security phone number depends on the DHS office or program that handles your issue. Start with the verified contact block on this page for the department’s main channel, or use the official DHS contact directory to find program-specific support.

What are the official Department of Homeland Security phone contacts?

The main DHS contact channel handles general questions and helps route inquiries, but it may not manage individual cases. A program-specific support line connects callers with the office that owns a particular application, report, request, or case.

Use the verified contact block above when you need the department’s general contact information. If you searched for a department homeland security phone number or a phone number for Department of Homeland Security, confirm that the displayed contact comes from DHS rather than an advertisement, directory listing, or social media post.

For a case involving a named DHS component, check that component’s official contact listing. A component is an agency or office operating within the department. Using the relevant component’s channel can prevent delays caused by sending a question to the department’s general office.

Which DHS office should I contact?

Choose the DHS component named on your notice, case record, application, or previous correspondence. If no office is named, identify the subject of your question before opening the DHS contact directory.

• For immigration or citizenship matters, look for the DHS component responsible for the application, petition, benefit, or enforcement matter shown on your paperwork.
• For airport screening or traveler questions, choose the travel-security program identified in your notice or account.
• For trusted-traveler, customs, border, or entry questions, select the border-related component associated with the record or program.
• For federal cybersecurity reports or guidance, look for the cybersecurity component and the category matching the affected organization or system.
• For disaster-response questions, use the disaster-response component identified in the relevant application, notice, or correspondence.
• For another security-related matter, use the DHS directory description to match the topic with the responsible office.

Do not assume that one DHS office can view another office’s records. The agency or program name on an official document is usually the most useful routing clue.

How do I contact DHS customer service?

Department of Homeland Security customer service is a set of official public-contact channels, not a commercial call center. The department’s general channel can address broad questions or direct you to the appropriate component, while case-specific help normally comes from the program managing the record.

1. Open {site} and find the contact or directory section.
2. Select the agency, office, program, or topic that matches your issue.
3. Choose the official phone or online contact option shown there.
4. If you need an accessibility option, review the accessibility information attached to that official contact channel.
5. Follow only the instructions displayed by DHS or the responsible DHS component.

If your search was for the Department of Homeland Security customer service number, compare the result with the verified contact block on this page or the current DHS directory before calling. Contact information and routing procedures can change.

What should I have ready before calling DHS?

Prepare enough information to explain the issue without disclosing sensitive details before the representative confirms what is required. Having a short, organized summary makes it easier for the receiving office to decide whether it owns the matter.

• The full name of the DHS agency, office, or program involved.
• Any case, receipt, report, application, or reference number shown on official records.
• Relevant dates, including when a filing, report, notice, or contact occurred.
• The title or subject line of any notice or message you received.
• A concise description of what happened and what information you need.
• Notes about earlier contact attempts, including which office you reached.
• Any communication or accessibility accommodation you need.

Keep the original document nearby so you can read labels accurately. Do not post case numbers, identity documents, passwords, verification codes, or other sensitive information in public comments or unofficial forms.

What if I cannot reach the right DHS office?

If a Department of Homeland Security contact cannot handle your question, ask which component or program owns the issue and what official directory category you should use. A general office may be able to identify the destination even when it cannot access the underlying record.

1. Check the agency or program name on your notice, account, or case document.
2. Return to the official DHS contact directory and match that name to a listed component.
3. Confirm that the contact channel appears on {site} or on an official page belonging to the named component.
4. When contacting the new office, state that another DHS office redirected you and briefly describe the issue.
5. If the office still cannot help, ask for the exact office or program name rather than relying on an unverified number supplied elsewhere.

An official government contact should be traceable through DHS or the responsible component’s official presence. Search-result snippets, copied directory entries, and caller-ID labels are not enough by themselves to verify a channel.

How do I report suspicious DHS calls or messages?

Do not disclose passwords, verification codes, financial account details, or identity-document numbers to an unverified caller claiming to represent DHS. Caller ID, email display names, text-message labels, and copied logos can be misleading.

End the contact if you are unsure, then independently locate the relevant DHS component through the official DHS contact directory. Compare the caller’s claim with current DHS guidance about scams, fraud, and impersonation before responding.

Official DHS guidance explains how to recognize suspicious contact and identifies the appropriate reporting channel for the type of incident. Use the reporting method named in that guidance; do not reply to the suspicious message or use contact information supplied by the sender.
