Date Of Birth For Beneficiary

[Guest Taxwoman]

Is it mandatory to have the date of birth for a designated beneficiary of an IRA?

I know it is recommended- but the IRA owner does not know the DOB of the individual and wants to designate him as the beneficiary without his knowledge ( for personal reasons)

There is no reason to know the date of birth of a non-spouse beneficiary until the account holder dies.
