The visas that are granted to anyone visiting the UAE for touristic or work purposes have one thing in common. All the visas have a six digit unique number printed on them. These numbers help to identify the person who is entering the UAE and keeps a record of their movement in and out of the country. Usually the UAE visa number will be stamped onto your passport page and the record of the number is maintained as soon as you set foot in the country. The maintenance of immigration records is very strict in the IAE and the visa number helps to smooth out the process.
