A quick summary provided by CompTIA: Transcript 5JJNQM12JJB1SLBV shows multiple certifications that have been obtained. (That transcript is set to expire, but is currently valid at the time of this writing.)

Also available, here, are some additional methods for having CompTIA verify the individual certifications.

CompTIA Linux+ (Powered by LPI)

TOOGAM's “CompTIA Linux+ (Powered by LPI) certificate.pdf” gives the code for CompTIA verification of the code 6X5S6BGD6K1EKSP9 and CompTIA's Fulfillment area provided another working code, verifiable with CompTIA verification of the code 2C7G9SGBRDQ11W7Y.

Pearson VUE's authentication can also be used, by the general public, to validate my passing of the related exams. For the first examination, this is done by using Registration Number 262451502 and Validation Number 444357741. For the second required exam, this is doable by using Registration Number 262451501 and Validation Number 482716540.

CompTIA KB 46: Third party verification states, “Candidates present proof of their CompTIA certification/s directly to the employer/educator by using either the PDF certificate feature or the ‘Transcript’ feature, both available through the candidate record database and both verifiable. These are the only CompTIA approved methods of certification verification available to our Certified Professionals.”

In the spirit of publicly revealing information about CompTIA certifications which have been obtained, PDF certifications provide official proof of the certifications obtained. are provided here. The certifications include a verification URL of http://verify.CompTIA.org and each certification also has a unique verification code. The verification URL redirects to CompTIA's secure verification form at certmetrics.com and that web page will accept the code from the certificate. For verified codes, the verification site will show the name of the certified person and the verification site will also mention that the certification is active.

I found that the “Fulfillment” record (available on the individual's logged in CompTIA account) also provides an additional code.
