Obtaining a PESEL number is the entitlement of the party and, in the case of Ukrainian citizens, enables them to benefit from special forms of assistance intended for them. The question asked refers to the PESEL number assigned under Article 4 of the Act on Assistance to Ukrainian Citizens in connection with Armed Conflict on the Territory of the State. The provisions of this Act are national in nature and cannot affect the legislation of other countries – and it must be stressed that the United Kingdom is not a member of the European Union. The national law of one State cannot determine the law of another one. Against this background, it is not the Act on Assistance to Ukrainian Citizens in connection with Armed Conflict on the Territory of the State that will determine the possibility of granting assistance in another state (both EU and non-EU). In the context of the question asked, the questioner should verify the legislation of the country to which he/she intends to travel.
