The Unified Identification Number is a six-digit number automatically assigned to anyone who enters the UAE. The number is used as an identification tool for individuals entering the UAE and to maintain the Immigration records. It is also necessary for residence visa applications and Emirates ID processing. Meydan Free Zone’s UID Number Merging service can be initiated in cases where individuals are assigned multiple UID numbers which creates duplicate records in the Immigration System and will cause problems upon entering and exiting the UAE; and when applying for residency visa. Therefore, multiple UID numbers must be merged for Immigration records to be reconciled.
