Affiliate disclosure

Last updated: 2026-06-16

As an Amazon Associate I earn from qualifying purchases.

1. What affiliate links are

Some pages on Passport Validity Buffer Check contain affiliate links. If you click one of those links and make a purchase on the destination site, the owner of this site (José Manuel Volante González) may receive a commission from the seller. The commission is paid by the seller; it costs you nothing extra and does not change the price you pay. This disclosure is made in line with the FTC's endorsement guides (16 CFR Part 255) and EU transparency rules (Directive 2005/29/EC).

2. Programmes we participate in

• Amazon Associates Programme (Amazon US / EU / UK): links to products on amazon.com, amazon.es, amazon.co.uk and other Amazon marketplaces.
• Other affiliate programmes (Awin, CJ, direct partners) where indicated on the relevant page.

3. How this affects our content

Affiliate commissions fund the maintenance of this free tool. The validity verdict is computed exclusively from the published validity rules in our versioned dataset: the presence of an affiliate link never alters the result or its ordering.

4. How links are identified

Affiliate links carry the attribute in line with Google's guidelines and applicable transparency requirements.
