Issue documents and memberships through Authstamp. Anyone you share them with can confirm they’re real in seconds, without calling you.
Free for holders and verifiers. 10 free stamps a month for issuers.
Banks, companies, associations and government offices that issue letters, certificates and memberships. Associations can add members in bulk, set renewal dates and issue verifiable membership instead of paper cards. Use it online, or install it on your own servers.
Receive documents and memberships, keep them in one place, and share them anywhere. Your membership stays checkable for as long as it’s active.
Always free
Check a document by its code, or confirm someone is a current member using their member number. Single checks are free. The API and bulk checks are paid.
The issuer stamps a document, or adds a member and issues their membership. Authstamp records it and gives it a unique code.
The holder downloads the document or membership and sends it by email or WhatsApp, or shows it on their phone. Holders never pay.
Anyone scans the QR code, types the code, or enters a member number. Authstamp checks the live record, so a forwarded copy still works and an expired membership shows as expired.
Prove a banking relationship without anyone calling the branch.
Registration and compliance certificates that buyers can check before awarding a tender.
Letters, undertakings and certified copies from law firms that the other side can confirm in seconds.
Bodies for accountants, engineers and other professions show a member is in good standing today, not just when the certificate was printed.
Replace paper cards with membership that expires on time and can be checked by member number.
Permits and licences that officers and the public can check on the spot.
