We have hospital numbers or national insurance numbers even DVLA so my thoughts are ..we only need to present ONE of these to who ever is asking ( in authority)
DONT start another hi flung business deal with a moron somewhere like covid! I remember NASA spending millions on a pen that would write upside down in space and when asked the cosmonauts what they used ? They said 🤔 a pencil! This is not rocket science ...we have data stored in many ways ..if you cannot produce one singular bit of paperwork ?- I would say then you are dodgy for whatever reason .. I think we need to revoke reasons for staying in the UK. Keep your driver's licence on you 👍 even if revoked as dvla can advise why this was the case. If you were not registered with a GP and have healthcare NHS No with NHS access to the website - good on you .. t - register or be revoked. No UK visa the same. You need to provide who you are rather than a right to something, or a feeling to a right to belong.
