Time work.. again

Where? Adler, sea-side boardwalk

«Time work» seems to be popular here to showcase working hours.

I have several store/cafe signs with common abbreviations some businesses have to publicly display, which almost everyone translates/transliterates differently. I’ll explain them here, as they are present on this sign too…

ООО , seen mostly as OOO
Общество с ограниченной ответственностью — Limited liability company (LLC)

ИНН , seens as INN, INT
Идентификационный номер налогоплательщика
Taxpayer number, something like Value added tax identification number (VATIN) or TIN (Taxpayer Identification Number)

ОГРН , seen as OGRN, GSRN, BNRN
Основной государственный регистрационный номер
Primary state registration number for businesses

The international standard ISO 2384 states that, if abbreviations are used in the text, their equivalents in the language of the translation should be given. If there is no equivalent, the abbreviation should be fully explained at its first occurrence.
