A growing trend in financial institutions is performing rule based auto elimination on secondary attributes. So for example when we have a match on a name; but a mis-match on a secondary attribute such as date of birth, nationality, or location; then the match will be eliminated before a person looks at it.
We at SQA Consulting only encourage this practise, but it should be done with care, computer based rules have no lee-way for applying common sense, so your rules should be precise and cover all eventualities.
For most people in the world defining which country you are located in is trivial, the overwhelming majority of people are located in one of the 193 member states of the United Nations. A smaller number of people live in one of the other 56 nations that have an ISO Country Code, but are not directly in the United Nations. However some people are located in one of at least 160 disputed regions of the world where the country is harder to define.
When it comes to sanctions screening we find that the following problems of location definition occur over and over again, both in address records that a financial institution holds, and on list records maintained by listing authorities.
Hong Kong – China, Hong Kong has long been an independent state with its own ISO Country Code – HK. Since its re-incorporation back into China it has retained its HK Country Code even though it is not officially a separate country. Some addresses will refer to the country as Hong Kong, some China, some Hong Kong Special Administrative Region of the People’s Republic of China. It would be unwise to eliminate a match on a location difference of Hong Kong vs China without looking further at the full address.
Kosovo – Serbia, Kosovo is a partially recognised state that is officially in Serbia. Kosovo does not have an ISO Country Code but many organisations are using XK to represent it. Note that all ISO Country Codes beginning with X are user defined and SK as a Country code has no universal acceptance. It would be unwise to eliminate a match on a location difference of Kosovo vs Serbia without looking further at the full address.
Sudan – South Sudan, South Sudan split away as a separate country from Sudan in 2011, addresses in South Sudan recorded before 2011 will state Sudan. However the real and current problem for sanctions screening is that there is a disputed territory on the border of the two countries: Kafia Kingi, currently officially in South Sudan this area is disputed because of its mineral rich land, however it is a hide out area for terrorists. Many lists feature addresses in Kafia Kingi and sometimes it is listed as Sudan, sometimes as South Sudan. It would be unwise to eliminate a match on a location difference of Sudan vs South Sudan without looking further at the full address.
Isle of Man – United Kingdom, the Isle of Man and the United Kingdom are different countries with different ISO Country Codes (IM and GB). However there are instances on the EU sanctions list of addresses in the Isle of Man having a Country Code of the United Kingdom, and this is not the only place we have seen this. The Isle of Man and the UK are very close neighbours, the Isle of Man is a British Crown Dependency, and there are many instances of British companies having representation on the island. It would be unwise to eliminate a match on a location difference of Isle of Man vs United Kingdom without looking further at the full address.
These are the issues we see commonly, there are others, and great care should be taken you have an accurate unambiguous definition of location.
