The Board's procedures for adjudicating and processing applications and claims for unemployment benefits filed pursuant to this part will include both pre-payment and post-payment procedures for verifying the validity of such applications and claims. Such procedures shall be designed with a view to obtaining substantial evidence as to the days of unemployment of the employees who register in accordance with this part. The verification procedures shall include, but are not limited to:
(a) Pre-payment contacts with railroad employers, utilizing data processing techniques to the extent feasible so as not to delay unduly the payment of valid claims; and
(b) Computer matching programs with state agencies or other entities that may have relevant data concerning non-railroad employment and benefit payments under state unemployment compensation laws.
