Help I screwed up

[Tremaine Kwasikpui]

So I have a tenant that moved into my property in March. Went through zillow with the application process. Tenant has 723 credit score. 3 times the rent etc. They paid prorated last in April. 

now no communication and no rent. I am working with eviction company to get the ball rolling. Now here is how I screwed up. 

Company needs her birthdate. I did not get the ID or social. Are there and credible sources where i can get the birthdate. I have previous addresses and middle name. Any help but non judgement welcome and appreciated

How did you find out credit score? Company that gave you credit score might be able to give you birth date.

Internet searches might help, too
