What this form asks for

The AI fills all of it, from your answers or your documents.

The ACORD 25, Certificate of Liability Insurance (COI), is a document that summarizes an individual's or organization's insurance coverage at a specific point in time. It is commonly requested by clients to verify that a vendor or contractor has sufficient liability insurance before a project begins, protecting them from potential losses. The form details policy types, limits, and effective dates but does not alter the policy itself. Today this form can be filled out quickly and accurately using AI-powered services like Instafill.ai, which can also convert non-fillable PDF versions into interactive fillable forms.

The AI checks your answers before you download

14 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Validates NAIC Number Format and Presence

This check ensures that for each insurer name provided (e.g., 'Insurer A Name'), the corresponding 'Insurer NAIC Number' field is also populated with a valid 5-digit numeric code. The NAIC number is a critical unique identifier for regulatory and verification purposes. Failure to provide a valid, paired NAIC number can lead to the rejection of the certificate as the insurer cannot be properly identified.

Ensures Policy Expiration Date is After Effective Date

This validation compares the effective and expiration dates for each individual policy listed (e.g., 'WC Policy Effective Date' and 'WC Policy Expiration Date'). The expiration date must occur on or after the effective date to represent a valid coverage period. An inverted or illogical date range would invalidate the policy's term and render the certificate inaccurate.

Requires Retroactive Date for Claims-Made Policies

If the 'CGL Claims-Made Policy Option' checkbox is selected, this validation confirms that the 'Claims-Made Retroactive Date' field is populated with a valid date. The retroactive date is a fundamental component of a claims-made policy, defining the start of the coverage period for incidents. Omitting this date makes the policy terms dangerously ambiguous and incomplete.

Requires Description for 'OTHER' General Liability Policy

This validation ensures that if the 'OTHER (Other General Liability Policy)' checkbox is selected, the 'Other Policy Type Description' field is not empty. Selecting 'OTHER' without providing a description is meaningless and fails to inform the certificate holder about the nature of the coverage. This description is essential for understanding the full scope of liability protection.

Validates Insurer Letter Reference Integrity

This check verifies that any 'Insurer Letter' field (e.g., for CGL or Umbrella coverage) contains a letter (A-F) that corresponds to an insurer listed in the 'Insurer A' through 'Insurer F' sections at the top of the form. The letter acts as a crucial link between a specific coverage and its underwriter. An invalid or unassigned letter breaks this link, making it impossible to determine which company is providing that coverage.

Ensures All Liability Limits are Valid Monetary Amounts

This check scans all fields representing monetary limits (e.g., 'Each Occurrence Limit', 'General Aggregate Limit', 'Automobile Liability Combined Single Limit') to ensure they contain valid, positive numeric values. These limits represent the core financial information on the certificate. Non-numeric, negative, or zero values would render the document invalid for assessing coverage levels.

Common Mistakes in Completing ACORD 25

The ones the AI is built to catch.

Entering an Invalid or Incorrect NAIC Number
This mistake occurs when the user enters a policy number or an internal carrier code instead of the official five-digit NAIC number. The NAIC number uniquely identifies the insurance company, and using the wrong one prevents the certificate holder from verifying the insurer's financial stability. This can lead to the certificate being rejected, causing project or payment delays. To avoid this, always confirm the correct NAIC number for the specific insurance underwriter, which is often found on the policy declarations page.
Providing an Incomplete or Vague Description of Operations
Users often provide a generic or incomplete entry in the 'Description of Operations' section, failing to include specific project names, job numbers, or required legal wording. This happens when the specific requirements of the certificate holder are unknown or overlooked. An inadequate description can result in contract non-compliance and rejection of the certificate. Always obtain the exact wording required by the certificate holder and include all relevant details to ensure the certificate is accepted without issue.
Confusing the 'Insured' with the 'Certificate Holder'
A frequent error is swapping the information for the 'Insured' (the policyholder) and the 'Certificate Holder' (the party requesting proof of insurance). This fundamental mix-up invalidates the certificate's purpose and leads to significant confusion and processing delays. To prevent this, carefully verify that the entity covered by the insurance is listed as the 'Insured' and the party to whom the certificate is being provided is listed as the 'Certificate Holder'.
Improperly Checking 'Additional Insured' or 'Subr Wvd'
Checking the 'Addl Insd' (Additional Insured) or 'Subr Wvd' (Subrogation Waived) boxes without the corresponding endorsements on the actual policy is a critical error. A certificate only evidences coverage; it does not create it. This mistake misrepresents the policy's terms and can lead to severe legal and financial consequences if a claim occurs and the expected coverage does not exist. Before checking these boxes, always confirm that the required endorsements are active on the policy.
Misunderstanding 'Claims-Made' vs. 'Occurrence' Policies
Users often incorrectly identify a policy's type, confusing 'Claims-Made' with 'Occurrence' coverage. An 'Occurrence' policy covers events happening during the policy period, while a 'Claims-Made' policy covers claims filed during the policy period, often requiring a 'Retroactive Date'. Selecting the wrong type misrepresents the coverage terms, which can lead to denied claims. It is essential to review the policy declarations page to correctly identify the policy type and enter all related dates accurately.
Entering Inaccurate or Mismatched Policy Dates
Simple data entry errors, such as transposing numbers or using an incorrect format (e.g., DD/MM/YYYY instead of MM/DD/YYYY), are common when entering policy effective and expiration dates. An incorrect date can suggest a lapse in coverage, leading to immediate rejection of the certificate. To avoid this, carefully transcribe dates from the policy documents. AI-powered form filling tools like Instafill.ai can help prevent these errors by automatically validating date formats and flagging inconsistencies.
Using Non-Numeric Characters in Liability Limit Fields
When entering monetary values for liability limits, people sometimes include dollar signs ($), commas, or text like 'As per policy'. These fields typically require numeric values only, and extraneous characters can cause errors in automated processing systems, leading to rejection. Always enter only the numerical value for all limits (e.g., 1000000). Advanced tools like Instafill.ai can automate this by correctly formatting monetary values and removing invalid characters during data entry.
Mismatching the Insurer Letter with the Correct Insurer Name
This form uses letters (A, B, C, etc.) to link policies to the insurers listed at the top. A common clerical error is assigning the wrong letter to a policy, creating ambiguity about which company provides which coverage. This makes verification difficult for the certificate holder and may cause them to reject the form. To avoid this, carefully cross-reference the insurer letter next to each policy with the corresponding insurer name in the 'Insurers Affording Coverage' section.
Forgetting to Update the 'Revision Number' on Corrections
When a certificate is re-issued to correct an error, users often forget to increment the 'Revision Number'. This creates version control problems, making it difficult for the recipient to identify the most current and accurate certificate. Relying on an outdated certificate can lead to compliance issues. To prevent this, always update the revision number sequentially each time a certificate is amended and re-sent.
Leaving Address Fields Incomplete
Omissions in address fields, such as a missing suite number, city, or zip code for the Producer or Certificate Holder, are a common oversight. This can happen due to haste or not having the complete information. An incomplete address can prevent important legal notices, such as a notice of cancellation, from being delivered correctly, potentially leading to compliance failures. If the form is a non-fillable PDF, tools like Instafill.ai can convert it into an interactive version, making it easier to enter and review complete address details.
