Common questions

What is the difference between PINFL and STIR (INN)?

PINFL is the personal identification number of an individual. STIR (INN) is the taxpayer number; a company gets its STIR when it is registered.

Are EDS, ЭЦП and E-IMZO the same thing?

Yes. They are the English, Russian and product names for the same electronic digital signature key.
