In most jurisdictions, yes. But there is no open standard for these
across different countries.

The most common system is the DUNS number
(http://en.wikipedia.org/wiki/Data_Universal_Numbering_System). But this
is controlled by one company which provides company data on a commercial
basis, so it's preferable to avoid it where possible.

You can try using the opencorporates reconciliation API to get their
standard ID for a company. This will help map from free text to a
company identifier, and will get you a link to the official company
registry in many countries. See
http://api.opencorporates.com/documentation/Home

As for getting financial information: it depends. For UK companies it is
available in (paid) company filings. Duedil.com make it available for
free, but their API costs several thousand pounds per month. I'm not
aware of good free global data sources on revenues; if you find any, I
would be glad to hear about them.

best,
Dan
