Draft Zip Code Attestation For Free

ZIP Codes are numbered with the first digit representing a certain group of U.S. states, the second and third digits together representing a region in that group (or perhaps a large city) and the fourth and fifth digits representing a group of delivery addresses within that region.

So what do the extra numbers mean? These last 4 digits represent specific delivery routes within delivery areas. This extra detail means an even more precise matching to a more granular level. It could represent a handful of houses on one side of a street, or even a single building that receives a high volume of mail.

Attestation is built-in to the FIDO and WebAuthn protocols, which enables each relying party to use a cryptographically verified chain of trust from the device's manufacturer to choose which security keys to trust, or to be more skeptical of, based on their individual needs and concerns.

History & Development The ZIP in ZIP Code stands for Zone Improvement Plan, and it was introduced July 1, 1963, as part of a larger Postal Service Nationwide Improved Mail Service (NIMS) plan to improve the speed of mail delivery.

Attestation refers to the capability of a FIDO Authenticator to provide a cryptographic proof about its model to a remote relying party.

Attestation is a legal acknowledgment of the authenticity of a document and a verification that proper processes were followed.

WebAuthn is part of the FIDO2 framework, which is a set of technologies that enable passwordless authentication between servers, browsers, and authenticators. As of January 2019, WebAuthn is supported on Chrome, Firefox, and Edge, and Safari.
