Identifiers get a repeatable answer.
GTIN and Digital Link results come from deterministic, tested code. A model does not decide whether an identifier passes.

Why / 01
Why Stampwright starts with the catalog
A wrong check digit, reused GTIN, or stale destination can travel from a spreadsheet into artwork and printed inventory. Fixing it at the source costs less than correcting packaging later.
The free audit returns row-level findings for identifier validity, duplicates, missing product names, and GS1 Digital Link syntax. It reads the source file to produce a worklist and leaves that file unchanged.
Method / 02
How the work is handled
Product facts stay with the customer.
Stampwright works from customer-supplied product facts. The brand remains responsible for what a product says and where an approved route should lead.
Digital preflight ends at the file.
Artwork preflight can check one QR Code's data, size, quiet zone, and estimated contrast. A qualified verifier still needs to scan a printed sample before production.
Company / 03
Who is behind Stampwright
Stampwright is the operating name of Sunrise2D LLC, an Austin, Texas company owned and operated by Angell Tsang.
Angell is accountable for customer agreements, product commitments, and decisions that affect customer packaging. Software handles repeatable checks and monitoring.
Boundaries / 04
Where the product stops
The useful boundary is the one a customer can see before relying on the result.
An industry target is not a universal deadline.
Sunrise 2027 is an industry target, not a law or universal retailer mandate. Confirm timing and symbol requirements with each trading partner.
Stampwright is independent.
Stampwright is not affiliated with, endorsed by, or certified by GS1, GS1 US, or any GS1 member organization.
A syntax result has a narrow meaning.
A passing result means the URL passed automated conformance checks against GS1 Digital Link syntax. It is not a claim of certification or full resolver conformance.
A screen cannot prove a print run.
Ink, substrate, curvature, and the production process remain outside a browser check. Have a qualified verifier scan a printed sample before production.
