Hi Sudesh,
My 2 cents. Anytime, you have a changed address on the document, verify on the GTS side and assess if you have the below errors for the document. It will be more easier to decide as to what all the system has found as hits.
As Vaibhav asked, how are you suggesting that the system is considering the email id or phone numbers? Does it bring up on the hits list in GTS? The system should consider only those fields you have set up as part of address comparison.
If you want to see a different behavior where the system shouldn't consider any address changes on the document, try the setting "1 Status Check of Unchanged addresses" under check logic of docs setting. You can view it under "control settings for SPL screening"
Hope it helps!
