What does the "Verified" badge mean on PVFirms?
A Verified badge means PVFirms has independently confirmed the company's legal registration, physical address, and active business status in their listed country. We do not accept payment for Verified status — it is awarded solely based on our editorial review criteria.
How does the PVFirms verification process work?
Every company that applies for verification goes through a three-step review: (1) Identity Match — we confirm the business registration number, VAT/Tax ID and legal name against national company registers; (2) Domain Authority — we verify the company's web presence and contact channels are consistent; (3) Physical Presence — we confirm a real operating address in the listed region. Verified status is reviewed annually.
