What to do if it is mine tax identification number registered abroad without my knowledge?

Short answer

If you find out that your tax identification number (with Slovak prefix 0245) is already in the network Peppol registered with a foreign provider (e.g. in Poland or Belgium), although you have not consciously requested it, you must contact this provider and request that registration be revoked. Financial Administration this situation is actively addressed with the authority of OpenPeppol, to ensure compliance with the national rules under which Slovak entities belong exclusively to the Slovak Central SMP. If you can't identify which mailman you are registered to, call center Financial Administration provide you with the name of the specific accredited provider after verification.
