This field map outlines key entry differences for certificate holders and additional insureds on standard ACORD 25 insurance certificates. Most standard certificate forms separate these two designations into distinct sections to avoid coverage disputes, administrative delays, and incorrect status filing for all parties. The below table maps core form fields to eligibility rules for each designation, for use when organizing your insurance policy folder or cross-checking a received certificate for accuracy. This guide is for reference only, it does not modify existing coverage, and all status confirmation requests should be directed to the issuing insurance provider or licensed broker, with resources available for standard form downloads via Clause Shelf for personal file organization.
| Form Field Location | Allowed Entry Type | Certificate Holder Eligibility | Additional Insured Eligibility | Required Supporting Documentation |
|---|---|---|---|---|
| Top-left preprinted mailing box | Full legal entity name, mailing address, email, and cancellation notification contact | Allowed, exclusive designated field for this status | Not allowed; entries here do not confer valid additional insured coverage | Copy of signed contract requiring proof of insurance submission |
| Middle editable additional insured section | Full legal entity name, DBA (if applicable), and associated project/contract reference | Not allowed; entries here do not confer certificate holder cancellation notification rights | Allowed, must match pre-approved endorsement language filed with the carrier | Copy of signed additional insured request form submitted to the issuing broker |
| Bottom coverage scope note field | Plain language coverage limits, exclusion terms, and endorsement effective/expiration dates | No applicable entries; no coverage is extended to certificate holders | Allowed, terms must align exactly with filed carrier endorsement | Copy of signed contract specifying required additional insured coverage scope |
| Attached carrier endorsement schedule | Typewritten list of all parties approved for extended coverage | Not listed on this binding document | Required listing for coverage to be legally enforceable | Official endorsement document issued directly by the named insured’s insurance carrier |
| Cancellation notification recipient field | Mailing address and contact for policy lapse, non-renewal, or cancellation alerts | Allowed, certificate holders are legally entitled to these notifications | Not allowed; notifications are only provided if explicitly added via a separate endorsement | Written request for cancellation alerts submitted to the issuing agent at the time of certificate issuance |
Preprinted form box for certificate holder mailing and contact details
This section is typically located in the top-left quadrant of standard ACORD 25 forms, and is preformatted to only accept contact information for the party requesting proof of insurance coverage. Certificate holders are not extended any coverage under the named insured’s policy, but are designated to receive formal confirmation that the policy is active, meets required coverage limits, and will receive written notice if the policy is canceled, non-renewed, or lapsed for non-payment during the certificate term. All entries in this section must match the full legal name and official contact information of the requesting party, as listed in the underlying contract that required the certificate submission. Entries for additional insured parties in this section are not recognized by carriers as valid for coverage purposes, and will not result in extended coverage for the listed party. You should cross-check this section against your contract’s listed contact information immediately upon receiving a certificate to ensure cancellation alerts are sent to the correct address.
Additional insured endorsement section editable entry fields
This separate, clearly marked section is located below the policy details section of the form, and contains open, editable fields for listing parties that are being extended limited coverage under the named insured’s policy as part of a contractual agreement. Entries here must include the full legal name of the additional insured, any applicable doing-business-as names, and a brief reference to the underlying contract or project that the endorsement applies to, to avoid scope ambiguity. All entries in this section must be pre-approved by the issuing insurance carrier, and cannot be added by the certificate holder or named insured without formal carrier endorsement. Unlike certificate holders, parties listed in this section are eligible to file claims under the named insured’s policy for covered losses that fall within the scope of the endorsement. Handwritten alterations to this section after the certificate is issued are not considered valid, and any required changes must be submitted to the issuing broker for a revised, re-signed certificate.
Bottom section note specifying additional insured coverage scope limits
Directly below the additional insured entry fields, this section contains mandatory plain-language notes outlining the exact scope, limits, and duration of coverage extended to listed additional insureds. These notes may specify coverage exclusions, applicable policy limits, project-specific restrictions, and effective and expiration dates for the endorsement, to ensure all parties understand the boundaries of extended coverage. Illustrative example: A note might specify additional insured coverage is limited to general liability claims arising from the named insured’s on-site work between 03/01/2024 and 11/30/2024, and excludes coverage for claims related to the additional insured’s own independent negligence or post-project warranty work. Certificate holders do not have any coverage terms listed in this section, as their designation is only for proof of coverage receipt and cancellation notification purposes. You should highlight any scope limits relevant to your contractual agreement and store a annotated copy of this section in your insurance file for quick reference.
Attached endorsement schedule listing all named additional insured parties
The certificate of insurance itself is not a binding coverage document, and all additional insured designations are only enforceable if the party is listed on the formal endorsement schedule filed with and issued by the named insured’s insurance carrier. This schedule is required to be attached to all distributed certificates, and contains a full typewritten list of all parties approved for additional insured status, along with full terms of the endorsement that supersede any handwritten notes or entries on the main certificate form. Certificate holders are not listed on this endorsement schedule, as they do not receive extended coverage under the policy. You should always store a full copy of this attached schedule in your insurance records folder alongside the main certificate, to avoid disputes if a claim is filed during the policy term. If the schedule is missing from a received certificate, you should contact the issuing broker immediately to request a complete copy before approving the certificate as compliant with your contract terms.
Issuer contact field for certificate holder status confirmation requests
Located in the bottom-right quadrant of the standard form, this section lists the full contact information, license number, and official signature of the insurance agent or broker that issued the certificate on behalf of the carrier. Both certificate holders and additional insureds may use this contact information to submit formal requests to confirm their designation status, verify active policy coverage, confirm that the required endorsement has been filed with the carrier, and request official copies of the endorsement schedule for their records. All confirmation requests should be documented in your file with the date of the request, the name of the representative you spoke with, and any reference number provided, for future reference if a coverage dispute arises. You should only rely on written confirmation from the issuing broker or carrier for status verification, as verbal confirmation is not considered legally valid for coverage disputes.
Within 3 business days of receiving a certificate of insurance, cross-reference all listed certificate holder and additional insured entries against your signed contract terms, then file a copy of both the certificate and attached endorsement schedule in your dedicated insurance records folder.
