The insurance company only provides whether the insurance policy is valid, signed and undated.
Hello! According to the format of practical writing, all styles need to be signed and dated. If there is no date, then the contract is incomplete and invalid in this sense. If the format of the year, month and day is indicated on the contract, and the agent does not ask you to write it, or the agent writes it for you, it will not affect the validity of the contract.
