# Certification Verification Tool The Linux Foundation provides a [verification tool](https://training.linuxfoundation.org/certification/verify-certifications) that allows users (e.g. potential employers or clients) to validate the status of an individual’s certification. To submit a query on this verification tool, a user must enter the Certificate ID number and the Last Name listed on the certificate of a successfully certified individual. (The Last Name must be entered exactly as listed on the Certificate, including any special characters.) The result for a successfully submitted query will include the full name of certificant, certification title and status (Current / Non-Current / Revoked) and the date that the certification was achieved. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
