UN M49 country codes

The numeric UN M49 identifiers (842 for USA, 156 for China) that key the reporterCode and partnerCode columns in Comtrade queries, paired with ISO alphabetic equivalents in reporterISO.

In this catalog it appears concretely: - UN Comtrade Plus TradeFlow acquisition_notes — "Reporter/partner use UN M49 numeric codes (842=USA, 156=China)". - UN Comtrade Plus TradeFlow fields — "reporterCode', 'reporterISO', 'reporterDesc', 'partnerCode', 'partner2Code". - UN Comtrade Plus TradeFlow coverage geographic field — "Global - reporters and partners covering essentially all trading economies".

A table is only as good as the column you actually need. If this field is absent, sparsely populated or defined inconsistently across rows, no amount of surrounding richness rescues the analysis, so it deserves its own line in your evaluation checklist.

The failure mode is concrete: the label appears in a listing, the delivered files tell a different story, and the gap surfaces mid-project when fixing it is most expensive.

You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and UN Comtrade Plus TradeFlow acquisition_notes lets you inspect the real artifact before any budget is committed.

Treat every claim of this attribute as testable:

1. Open UN Comtrade Plus TradeFlow acquisition_notes and confirm its record — "Reporter/partner use UN M49 numeric codes (842=USA, 156=China)" — against the files you actually receive.
2. Open UN Comtrade Plus TradeFlow fields and confirm its record — "reporterCode', 'reporterISO', 'reporterDesc', 'partnerCode', 'partner2Code" — against the files you actually receive.
3. Open UN Comtrade Plus TradeFlow coverage geographic field and confirm its record — "Global - reporters and partners covering essentially all trading economies" — against the files you actually receive.
