FAQ

What is SOS verification?

SOS verification ensures that a business is legally registered and recognized by the Secretary of State (SOS). It validates key information, such as business name, registration status, and compliance with state regulations. This helps prevent fraud and builds trust in business relationships.

What information is needed for SOS verification?

To verify a business, you typically need:

Business name

Registered address

BEIN or TIN (Taxpayer Identification Number)

State of incorporation

Additional details, like UBO (Ultimate Beneficial Owner) data, may be required for comprehensive checks.

Can I verify a foreign business with a U.S. SOS?

U.S. SOS databases only verify businesses registered within their jurisdiction. For foreign businesses operating in the U.S., you may check for 'Foreign Qualification' filings, which show registration in a state other than the business's home country.

What is an Ultimate Beneficial Owner (UBO), and how is this information verified?

A UBO is an individual who owns or controls at least 25% of a business. Verification includes cross-checking government registers, legal filings, and other public records to confirm ownership details and assess associated risks.

What is the enhanced due diligence procedure in UAE?

If a business is missing from SOS records, it might:

Be registered under a different name (DBA or trade name).

Have outdated or incorrect details.

Not be legally registered in the state.

Next steps include verifying with other states, consulting business owners, or checking federal databases like the IRS.

How frequently is SOS data updated in the database?

SOS databases are updated regularly, though the frequency varies by state. Signzy ensures near real-time updates by syncing with these data sources frequently to maintain accuracy.

How long does it take to complete an SOS verification?

Most SOS verifications are instant when conducted electronically. Manual verification or retrieving documents may take up to a few business days, depending on the state's processing time.

How does SOS verification help meet KYB requirements?

SOS verification ensures that businesses are legitimate, active, and compliant with local laws. This helps fulfill KYB, AML (Anti-Money Laundering), and CDD (Customer Due Diligence) requirements, reducing the risk of partnering with fraudulent entities.

Is the data collected during verification secure?

Yes. Signzy employs industry-leading encryption, secure APIs, and strict access controls to protect sensitive business data. Compliance with GDPR, CCPA, and other privacy regulations ensures user data remains secure.
