How we research and verify compliance data
Retailer chargeback rules are scattered across vendor portals, routing guides, and EDI specifications, and they change often. This page explains where our data comes from, how far we have verified it, and how we keep it current, so you can judge how much to rely on any figure before you act on it.
Where our data comes from
Each record starts from primary and reputable secondary sources: a retailer's own vendor guides and supplier portals, the GS1 barcode and labeling standards, and the ANSI X12 EDI specifications that define transactions like the 850, 856, and 810. Where a retailer does not publish a detail openly, we rely on established industry references and label the record accordingly.
We publish facts in our own words. We do not reproduce a retailer's copyrighted vendor manuals, and every record names the source it was drawn from so you can trace it back.
The verification ladder
Not every record carries the same confidence, so we mark each one with its stage. The badge on a code page tells you exactly where it sits.
Sample
Illustrative placeholder data used only to demonstrate page structure. The figures are not accurate compliance values and should not be acted on.
Extracted from source, pending expert review
Drawn from a named public source and written up accurately, but not yet reviewed by an independent EDI or vendor-compliance specialist. Most of our records are at this stage today. Treat them as a well-sourced starting point, and confirm the specifics against the retailer's current official documentation before you act.
Verified by an EDI specialist
Reviewed against official documentation by a practitioner with hands-on EDI and retail-compliance experience. When a record reaches this stage, the reviewer is named.
How we keep it current
Retailers revise fine amounts, thresholds, and routing rules without much notice, so a figure that was right last quarter can be wrong today. Every record shows the date it was last reviewed. When a retailer changes a rule we know about, we update the record and move the review date forward. If you spot something that no longer matches your vendor portal, tell us and we will check it.
What this is, and what it is not
GetChargeback is an informational reference and a pre-shipment scanning tool. It is not legal, financial, or compliance advice, and it is not affiliated with any retailer it documents. Retailer names are used only to identify the programs we describe. The authoritative source for any requirement is always the retailer's own current vendor documentation.
Found an error?
Accuracy matters more to us than volume. If a figure looks wrong or a rule has changed, email support@getchargeback.pro with the code and the source you are seeing, and we will review it.
