How UnitAge makes money

Decoding a serial number is free. Some pages show a partner offer marked “Sponsored”, and we may earn money when you use it.

Partner offers

We don’t show any partner offers right now.

Partner links go through CJ, an affiliate network, which tells the partner the visit came from UnitAge. We don’t send a specific contractor your way, and we don’t sell your information.

Offers never change your result

Manufacture dates come only from documented serial-number rules. Whether an offer appears depends on the decoded age and published typical lifespans, never on which partner pays more, and no partner can change a result.

What partners never see

We don’t pass your serial number, photos, email address or saved equipment to partners. When you click an offer, we record which offer it was, why it was shown, the kind of page, and the brand and equipment type, so we can tell which offers are useful. We never record the serial number.
