Is there one single EORI format for the whole EU?

No. The EU uses an EORI concept, but the format commonly reflects a country prefix followed by a national identifier. Always confirm the expected structure for the competent authority issuing the number.

Can an EORI start with a country code?

In many cases, yes. A common representation is a two-letter country code followed by a national identifier. Some systems also use additional digits or check rules.

Does “valid format” mean “active and usable”?

Not necessarily. Format validation checks structure, not legal status. Official systems may confirm existence or registration status depending on access and the authority.
