当我为营销客户工作时，我们的业务是基于确定两个人是否相同 - “我们的记录显示鲍勃·史密斯。罗伯特·史密斯的回答与鲍勃·史密斯相同吗？”
我们的数据可以分为姓名、联系方式（地址、电话、电子邮件）和关系（阿隆佐在 Square Tires Inc 工作）。一旦数据被清理/标准化，我们就会将该实体与系统中可能的匹配进行比较。单个片段的匹配不足以归类为匹配。我们需要两个不同的段匹配才能将一个实体与另一个实体进行匹配。这很重要，因为匹配电话和地址可能会产生同一家庭的不同成员。根据您的标准，这可能就足够了，但通常还不够。
话虽如此，我认为您没有足够的信息来对电话号码 1234567 是原始用户还是电话号码被重新分配的人做出半权威的猜测。我会尝试捕获有关注册电话号码的实体的更多个人身份信息。使用不同的 PII 注册现有电话号码不会导致该号码的原始持有者失效，而仅表示新用户已加入。在您获得有关该号码的原始持有者拥有新联系方式的足够信息之前，您可能应该保留与该电话号码的关联。可能的情况是，第二个注册者提供了虚假号码，或者任一申请人弄虚作假，而您不知道哪个号码是准确的。
您仍然可能会遇到公司发行的手机的问题。一家公司有一批分发给人们的电话。人们辞职并被雇用，这些电话号码仍然是公司的域名，但会分配给随后注册您的服务的人员。
希望这有助于为您提供解决问题的一些起点。
Back when I worked for a marketing client, our business was based on determining whether two people were the same - "our records show Bob Smith. Is the Robert Smith who responded the same as Bob Smith?"
Our data could be segmented into name, method of contact (address, phone, email) and relationship (Alonzo works for Square Tires Inc). Once the data had been scrubbed/standardized, we would then compare that entity to possible matches in the system. Matching on a single segment was insufficient to categorize as a match. We required two different segment matches for an entity to be matched to another. This was important as matching phone and address might yield different members of the same household. Depending on your criteria, that might be sufficient but generally it is not.
With all that said, I don't think you have enough information to make a semi-authoritative guess as to whether phone number 1234567 is the original user or a person who has had their phone number reassigned. I would attempt to capture more personally identifiable information about the entity registering the phone number. The registration of an existing phone number with different PII would not cause the original holder of the number to become invalidated, it merely signifies that a new user has come onboard. Until you get enough information back about the original holder of that number having a new method of contact, you should probably retain the association to the phone number. It could be the case the second registrant supplied a bogus number or either applicant fat-fingered their number and you wouldn't know which was accurate.
You can still run into issues with say corporate issued mobile phones. A company has a pool of phones they distribute to folks. People quit and get hired and those phone numbers remain the domain of the company but are assigned to people that then register for your service.
Hope this helps give you some starting points for solving the problem.
