A charge from “NATIONAL SECURITY SVC” on a card statement is typically related to contracted security guard services provided to a business, organization, property owner, or event organizer. This could reflect short‑term coverage (such as event or construction-site security), ongoing guard contracts for buildings or communities, or specialized services like fire watch or mobile patrols. In some cases, particularly for government or institutional clients, the charge may be associated with a project-based or contract-based invoice processed by card instead of via check or ACH.([guardstogo.com](https://www.guardstogo.com/armed-security-guards/?utm_source=openai))

To verify or resolve questions about a charge, cardholders should first confirm whether they are associated with a business, HOA, organization, or event that recently engaged outside security services. Reviewing invoices, contracts, or email confirmations from NSS/GuardsToGo and matching them to the transaction date and amount can help clarify the charge. If there is still uncertainty, customers can contact National Security Service via the phone and email listed on guardstogo.com, provide the transaction details (date, amount, last four digits of card), and request a copy of the related invoice or service order. If a charge appears unauthorized and cannot be matched to any known engagement, cardholders should promptly dispute it with their bank or card issuer after attempting to contact NSS.([guardstogo.com](https://www.guardstogo.com/contact-us/?utm_source=openai))

Frequently Asked Questions

Why do I see a charge from “NATIONAL SECURITY SVC” on my card?

This descriptor typically refers to National Security Service, LLC, a nationwide security guard company. The charge is usually tied to services such as armed or unarmed guards, event security, construction-site security, fire watch, or mobile patrols that were arranged for a business, property, or event. Check whether you or your organization recently contracted security services through NSS or their GuardsToGo brand and match the invoice or quote to the transaction date and amount.

What types of services does National Security Service, LLC bill for by credit or debit card?

NSS may process card payments for one‑time or ongoing guard services, including commercial and residential security posts, construction-site security, school or church security, event coverage, mobile patrols, and fire watch services. Invoices for these services can be paid by card as an alternative to check or ACH, which is why you might see a card transaction rather than a traditional invoice payment.([guardstogo.com](https://www.guardstogo.com/?utm_source=openai))

Is the charge from National Security Service, LLC a subscription or a one‑time payment?

Most NSS charges are tied to specific service engagements or contracts and are not consumer-style subscriptions. However, if a property, HOA, or business has an ongoing guard contract, charges may appear on a recurring schedule (for example, monthly or per project milestone). To determine whether your charge is recurring, compare multiple months of statements and check your service agreement or invoices from NSS.

How can I confirm what my National Security Service, LLC charge is for?

Locate any proposals, quotes, or invoices you received from NSS or GuardsToGo around the time of the charge, and compare the billed amount, dates of service, and payment method. If you still have questions, visit guardstogo.com and use the published phone number or email (info@guardstogo.com) to contact their office. Provide your organization name, transaction date, amount, and the last four digits of the card so they can look up the specific job or contract.([guardstogo.com](https://www.guardstogo.com/?utm_source=openai))

Can I cancel upcoming security services and stop future charges from National Security Service, LLC?

Cancellation depends on your contract or work order terms. Many engagements require advance notice or may include minimum-hour commitments for scheduled guards. Review your signed agreement or quote for cancellation policies, then contact your assigned security coordinator or NSS customer service directly to request changes or cancellation. Ensure you obtain written confirmation that services and related billing have been updated or cancelled.([guardstogo.com](https://www.guardstogo.com/?utm_source=openai))

How do I request a refund or billing correction from National Security Service, LLC?

If you believe you were billed incorrectly—such as wrong hours, dates, or rates—gather all supporting documents (contracts, time sheets, emails, and invoices) and contact NSS using the customer service phone or email listed on guardstogo.com. Clearly explain the discrepancy and provide copies of your documentation. NSS can review the guard deployment records and, if warranted, issue an adjustment or refund. If the issue is not resolved, you may then contact your card issuer to dispute the charge.

Does National Security Service, LLC place temporary authorization holds on cards?

In some cases, NSS or the payment processor may place a temporary authorization hold when a card is first provided, especially for large or time‑sensitive jobs. This hold verifies that funds are available and may appear as a pending transaction. It should either convert to the final charge amount once the invoice is processed or drop off within several business days if not captured. If a hold remains pending for more than a week, contact NSS and your bank to confirm its status.

How can I contact National Security Service, LLC about a charge on my account?

You can reach NSS through the contact details listed on guardstogo.com, which include a toll‑free phone number and a central email address (info@guardstogo.com). When contacting them, have your organization name, transaction date, exact amount, and the last four digits of the card ready so they can identify the payment. You can also use their online quote or contact form to request a callback regarding a billing question.([guardstogo.com](https://www.guardstogo.com/?utm_source=openai))
