Verifying Digital Signature With SignNow
Award-winning eSignature solution
What verifying a digital signature means
Verifying digital signature means checking that a signed electronic record came from the claimed signer and has not changed after signing. In SignNow, that process depends on signer authentication, time-stamped activity, document history, and tamper evidence. For U.S. business use, the goal is not just speed; it is proof. A defensible verification record helps support ESIGN and UETA enforceability, while giving legal, compliance, and operations teams a clearer chain of custody for the file.
Why digital signature verification matters
Verifying digital signature helps confirm signer identity, protect record integrity, and reduce disputes about authorship. Under ESIGN and UETA, electronic signatures can be enforceable evidence when the workflow shows intent, attribution, and a reliable signing record.

How to verify a digital signature
Use this short workflow to review identity evidence, document integrity, and audit details in SignNow.
Open document:
Choose the signature record you need to validate and open it in SignNow. Review evidence:

Confirm encryption, document history, and any required compliance settings. Save proof:
Export the completed record for filing, review, or legal review.
How signature verification works
The verification process follows the signing record from access to archive, checking who acted, when it happened, and whether the file stayed unchanged.
Review access: Open the document and confirm the signer record. Inspect events: Check timestamps, IP data, and action history. Validate integrity: Confirm the hash and tamper-evident seal. Archive proof: Store the completed record with audit evidence.
Key controls for signature verification
Verify signatures with controls that protect identity, preserve document history, and make review easier for legal, compliance, and operations teams.
Audit record
Signature history shows who signed, when they signed, and what changed afterward, helping teams document integrity and support internal review without manual chase work.
Identity checks
Signer authentication options help match the authorization level to the transaction, from simple access checks to stronger ID verification for sensitive records.
Integrity seal
Tamper evidence protects the final file by showing whether the document was altered after signing, which supports defensible recordkeeping and dispute review.
Compliance fit
Compliance alignment supports ESIGN, UETA, HIPAA, and other U.S. frameworks when the workflow is configured with proper access, retention, and audit controls.
Anywhere access
Mobile signing and browser access let teams review and verify signatures from the field, office, or home without changing the record format.
Record export
Exportable records make it easier to retain the signed document, audit trail, and supporting evidence together for legal, HR, or operational files.
User and permission management
Contract administrators in sales and procurement use shared templates and delegated sending in SignNow to route approvals while keeping permissions aligned with deal ownership and internal controls. Operations managers in multi-location businesses use admin controls to assign roles, manage templates, and keep sensitive agreements in the right hands during signature review.
Best practices for signature verification
Good verification depends on matching authentication strength, retention rules, and access controls to the document’s legal and operational needs.
Match risk to authentication
Preserve the audit trail
Use exact retention periods
Restrict record access
Common issues during verification
Weak authentication can make it harder to prove who actually signed, especially when the workflow relies on a shared inbox or a low-assurance link. Missing audit details leave gaps in the signing record, which makes later review harder when a document is questioned in court or internally. Poor retention processes can separate the signed file from its supporting evidence, including timestamps, access history, and signer events. Inconsistent handling of regulated records can create compliance gaps when teams apply the wrong retention period or store protected data without proper controls.
Risks of poor signature verification
Weak attribution
Record dispute
Audit gap

Troubleshooting signature verification
These answers cover identity checks, record retention, browser issues, compliance standards, and workflow controls used in SignNow.
Check whether the document was opened with the correct signer identity and authentication method. SignNow records audit details that support attribution, and stronger methods can be used for regulated workflows under HIPAA or 21 CFR Part 11.
Review the audit trail to confirm timestamps, event order, and file status. If the document history is incomplete, export the record and compare it with the completed file before treating it as final evidence.
Make sure the completed document was saved after signing and that retention rules match the record type. SignNow Business and higher plans support audit trails, while HIPAA records should be kept for 6 years under 45 CFR 164.530(j)(2).
Use a supported browser such as Chrome, Firefox, Safari, or Edge, and confirm TLS 1.2 or higher. If mobile review is needed, SignNow apps on iOS and Android can open signed files securely.
If you need stronger evidence for healthcare, finance, or FDA-regulated records, combine signer authentication, audit trails, and retention controls. SignNow supports workflows that align with ESIGN, UETA, HIPAA, and 21 CFR Part 11 requirements.
If a signing link was forwarded, review the authentication method and access controls. Shared access can weaken attribution, so use role-based permissions and stronger verification for documents that need clear signer intent.
